Things are looking bleak for the proposed LightSquared LTE network according to a story in PC World.

A key federal agency involved in testing the proposed LightSquared LTE network has concluded that there is no practical way to solve interference between that network and GPS, possibly dealing a crippling blow to the startup carrier’s hopes for a terrestrial mobile network.

That agency is the National Space-Based Positioning, Navigation and Timing Executive Committee (PNT ExComm). Now that’s a mouthful. The agencies that make up this one have unanimously concluded that none of the LightSquared proposals would overcome interference with GPS.

Here’s an excerpt from the letter to the FCC:

Earlier this week we published results of our ZimmPoll that showed a majority think the LightSquared proposal would be good for ag/rural America. However, most of those positive responses all came at nearly the same time.

Over the past year, the National Corn Growers Association has monitored issues surrounding the wireless broadband company LightSquared. While the Federal Communications Commission considers approval of LightSquared’s proposed terrestrial based broadband network, NCGA remains concerned about the effects it would have on precision farming. GPS technology has become an important tool for farmers as they improve their efficiency in seed, fertilizer and fuel usage.

“Strong and speedy Internet access is important to our growers, so NCGA supports the expansion of broadband in rural America,” said Ethan Mathews, manager of Public Policy and Regulatory Affairs for NCGA said. “However it must not come at the expense of high-precision GPS.”

Although LightSquared states that solutions to the interference problem have been developed by several independent companies, the company has yet to provide access to either the test results or the devices. Further, the FCC and the National Telecommunications and Information Administration are continuing their evaluation of theGPS interference issue. NCGA will look to the FCC and NTIA to ensure the issue has been resolved without loss to accuracy and performance.

In addition, NCGA will continue to work closely with John Deere, the American Farm Bureau Federation, the National Association of Wheat Growers and the American Soybean Association to ensure the GPS technology remains available to our farmers.

The American Farm Bureau Federation (AFBF) says the Federal Communications Commission (FCC) and an independent technical company must complete comprehensive and rigorous testing on all proposed technical fixes to ensure there is no interference between broadband and GPS signals that could be created by a broadband network being developed by LightSquared.

“It is critical that costs for resolving this issue are not passed along to farmers and ranchers through higher GPS or equipment costs,” AFBF President Bob Stallman said during a House Small Business Committee hearing on Wednesday. “LightSquared should cover the expense of all technical fixes related to the interference issue to ensure the cost is not passed along to farmers and ranchers.”

Many farmers rely on GPS for precision agriculture. This includes using GPS for accurate mapping of field boundaries, roads and irrigation systems; for precision planting; and for targeting the application of fertilizer and chemicals that combat weeds and crop diseases. GPS also allows farmers to work in their fields despite low-visibility conditions such as rain, dust, fog and darkness.

“While the deployment of broadband services is important for economic development, better education and improved health services in rural America, the use of precision agriculture is vital to America’s farmers and ranchers as they continue to feed, fuel and clothe the world,” Stallman said.

AFBF submitted comments to the FCC in July urging the agency to ensure there is no interference with GPS receivers prior to granting LightSquared permission to operate its high-powered base stations.

The latest report from USDA’s Economic Research Service on “Recent Adoption of Precision Agriculture” is about five years behind the times.

The report heralds that agriculture is “On the Doorstep of the Information Age” – using mostly information from 2005-06. According to the report, “recent data from the Agricultural Resource Management Survey (ARMS) show that use of yield monitors, often a first step in using precision technology for grain crop producers, has grown most rapidly, and was used on 40-45 percent of corn and soybean acres in 2005-06.”

The information for the study relies primarily on 2001 and 2005 surveys of corn, 2002 and 2006 surveys of soybeans, and 2004 and 2009 surveys of winter wheat – “the 2010 corn survey results were not yet available when this report was prepared” – which was this year. While there is some interesting data in the report, it is woefully out of date. Just think, if the survey had included questions about the use of smartphones on the farm, it would have been zero, since it was January 2007 before the first iPhone was introduced – and we’re now on the fifth generation. Point being, the adoption of all types of new technology has literally skyrocketed in the last five years.

Be that as it may, the most interesting findings in the report show that precision really does pay for farmers. For example, they found that corn and soybean yields were significantly higher for farmers using yield monitors compared to those who did not. In addition, farmers using yield monitors had lower per-acre fuel expenses. Average fuel expenses were lower, per acre, for farmers using variable-rate technologies for corn and soybean fertilizer application, as were soybean fuel expenses for guidance systems adopters and adopters of GPS mapping and variable-rate fertilizer equipment had higher yields for both corn and soybeans.

With all this new technology, you would think that USDA could find a way to gather, compile and disseminate information a little bit faster.

Yesterday Lightsquared announced a “solution” to concerns over interference with GPS systems from it’s proposed wireless broadband network.

LightSquared™, a wholesale carrier building a nationwide wireless broadband network that will create consumer choice and industry innovation, has signed an agreement with Javad GNSS Inc. to develop a system that will eliminate related interference issues for high-precision GPS devices.

The Javad GNSS system can be adapted to work with high-precision GPS devices including those already in the agriculture, surveying, construction and defense industries. (full release)

I’m not sure how forcing farmers and all kinds of people, especially those defending our country, to purchase new equipment that will have to be installed to keep their current GPS systems working is a real solution to what appears to be a very real problem. I’m all for more and better choices for broadband, especially in rural areas but not at the expense of GPS systems that perform very critical functions. This action seems to be an admission by Lightsquared that the concerns are real. Otherwise, why do this? I asked the Coalition to Save Our GPS for their response and got it right away.

“LightSquared has, as usual, oversimplified and greatly overstated the significance of the claims of a single vendor to have ‘solved’ the interference issue. There have been many vendor claims that have not proven out in rigorous tests and the demanding tests of marketplace acceptance. Moreover, this is not a one-size-fits-all situation and a few prototypes does not a solution make. The estimated 750,000 to 1 million high-precision GPS receivers now in use in the United States vary widely: there are hundreds of different high-precision devices used in performing thousands of different tasks. High-precision GPS supports a wide variety of uses, including agriculture, construction, aviation, surveying and many scientific and safety-of-life applications.

“In any case, this is not an issue that can be solved with a LightSquared press release. As the FCC and NTIA recently recognized, more testing is necessary to evaluate interference impacts under LightSquared’s latest technical proposals. We welcome the participation of Javad in those tests.”

There are Android and iPhone apps for just about everything.  My friend, Jason Webster runs the Practical Farm Research for Beck‘s Hybrids in Downs, Ill.  In addition he farms, too.  Jason fully admits he doesn’t always practice what he used to preach about scouting fields during the growing season.  Because of that – he’s gone to a more sophisticated form of scouting.  One that he utilizes and with full conviction can explain to farmers why they should make the leap to incorporate that technology into their farming operations, too. 

In this month’s Precision Pays Podcast, sponsored by Ag Leader Technology, Jason explains the future of finding problems in our fields.

The American Farm Bureau Federation (AFBF) is calling on the Federal Communications Commission to fully review possible interference to Global Positioning Systems (GPS) that could be created by a broadband network being developed by LightSquared.

“High-speed broadband services have great potential to bring opportunity to rural Americans, but should not jeopardize the Global Positioning System,” said AFBF President Bob Stallman. “Many of our farmer and rancher members rely on GPS for precision agriculture.”

“It is the accuracy of GPS that makes it useful to farmers and ranchers,” noted Stallman. Disruption to GPS could raise on-farm production costs.

AFBF submitted comments to the FCC in July urging the agency to ensure there is no interference with GPS receivers prior to granting LightSquared permission to operate its high-powered cellular base stations.

“Deployment of broadband services is important for economic development as well as improved education and health care services in rural America, but the use of precision agriculture also is vital to America’s farmers and ranchers as they continue to feed, fuel and clothe the world,” Stallman said.

The deadline for comments on the issue to FCC was today.

Kreg Freeman of Colquitt, Georgia is a double winner for his 2010 peanut crop that yielded a whopping 6626 pounds per acre.

Kreg, pictured here with University of Georgia Extension Peanut Agronomist John Beasley accepting his award as the statewide winner in the Georgia Achievement Club this year for the 100-300 acre category, credits a good part of his increase in profitability and yields to precision technology, as much as 500 pounds per acre. “We use GPS and auto steer tractors,” he told me. “What I got paid for the auto steer part of the tractor in one year.”

Kreg was also named as the Farm Press Publications Peanut Profitability Award winner for the Southeast during last week’s 2011 Southern Peanut Growers Conference. That award is based not only on yield, but production efficiency, honoring those growers who produce the highest yields at the lowest cost per acre.

Closing out the InfoAg Conference this year was a session on a very important topic. Titled, “GPS Under Seige: Lightsquared and the Threat to High-End Global Positioning,” this presentation was conducted by Kevin Kobb, Topcon (right) and Doug Schmuland, NovAtel. I spoke with them after their presentation. The threat comes from a plan to allow high-speed internet service to utilize GPS satellites to distribute their signal correction: high-powered, close-proximity transmissions from a network of ground stations that would cause substantial interference with GPS signals. This plan is currently in a comment phase at the FCC.

Kevin and Doug told me it has caused the major GPS producers and distributors to come together to understand the threat and then present that to the public and then work toward a favorable conclusion to the situation. The potential exists for this proposal to affect just about every device relying on GPS satellites. They say that now is the time to act and make your voice heard before the proposal receives a final FCC decision. You can find a lot of information on the website, Coalition To Save Our GPS.

The Coalition to Save Our GPS is growing as new evidence mounts that a proposed communications network would interfere with GPS systems.

A report was released last week by a Federal Communications Commission (FCC) technical working group on the potential for interference to GPS from the proposal by Virginia-based company LightSquared to set up 40,000 wireless broad-band stations across the nation on a frequency that is right next to the one used by GPS.

The FCC reports that the working group “identified significant technical issues” related to potential LightSquared interference in the upper portion of the L-Band, next to the band used by GPS. “The tests demonstrated potentially significant interference between LightSquared operations in the upper portion of the band and various GPS receivers,” the agency said in a public notice announcing a 30 day comment period on the issue.

“The report of the working group demonstrates there is no practical solution to mitigate the interference that would result if the proposal is allowed,” said Ken Golden of John Deere. “It is not acceptable to allow a new network to interfere with these vitally important industries and weaken the strong competitive position of the U.S. in the global economy. Research has shown that losing the use of GPS technology could have a negative impact of $14 billion to $30 billion annually for U.S. farmers.”

The coalition just announced an expansion of its membership last week, including new agriculture industry members such as AGCO, Agricultural Retailers Association, National Agricultural Aviation Association, National Cotton Council of America, National Rural Electric Cooperative Association, North American Equipment Dealers Association, and USA Rice Federation. The coalition reportedly now represents more than 100,000 companies and millions of individuals, either independently or through trade associations – including public safety, aviation, transportation, construction, technology, recreation, shipping, agriculture and consumer manufacturers.

Information on how to comment on the issue to the FCC can be found here. Comments must be received by July 30, 2011.

I love my TomTom.  I really am not sure what I would do without it.  I come from a small town in Central Illinois and I recently made a career move that took me to Indianapolis.  Tom is the best co-pilot a girl from small town USA that moved to the big city could hope to find.  He takes me turn by turn to my destination, coaxes me through wrong turns and rarely is he incorrect.  At this point, I can’t imagine my life without “him“. 

In this edition of the Precision Pays Podcast, sponsored by Ag Leader Technology, we explore GPS technology.  If you’re like me – and rely on your GPS just to navigate the roadways – imagine how heavily some industries (like agriculture, airlines, railways and even the New York City Fire Department) rely on the accuracy and efficacy of GPS in their daily operations.  What would happen if we lost the ability to use it?  This month we sat down with Sid Parks, Manager of Precision Farming with GROWMARK, and learned about the Coalition to Save Our GPS, how we could potentially lose it and why this is something for us to monitor.

A company planning to provide a wireless broadband/satellite network claims to have solved a GPS interference issue, but a new study finds interfering with GPS signals could cost the economy.

Officials with the Virginia-based company LightSquared, which wants to set up 40,000 wireless broad-band stations across the nation on a frequency that is right next to the one used by GPS, have outlined a proposal they say will address the problem of interference.

Early test results indicated that one of LightSquared’s 10MHz blocks of frequencies poses interference to many GPS receivers. This block happens to be the specific set of frequencies that LightSquared planned to use for the initial launch of its nationwide wireless broadband network.

Test results show this lower block of frequencies is largely free of interference issues with the exception of a limited number of high precision GPS receivers that are specifically designed to rely on LightSquared’s spectrum. In its original plan, LightSquared planned to move into this other frequency block as its business grew over the next two to three years.

Agricultural interests are concerned about that exception. A study released by the Coalition to Save Our GPS, which includes several agricultural technology companies, estimates that LightSquared’s plan could result in “direct economic costs of up to $96 billion to U.S. commercial GPS users and manufacturers.” Jim Kirkland, vice president and general counsel of Trimble, says the analysis “also highlights how LightSquared’s recently announced ‘solution’ to the interference problem, which LightSquared admits will not reduce interference for high precision GPS uses, is no solution at all. High precision GPS uses represent nearly $ 10 billion in historical investment by GPS users over the last five years and $30 billion in annual economic benefits.”

“The use of GPS technology is vital to thousands of people who make their living with agricultural and construction equipment. It is simply not acceptable to allow this new network to interfere with these important industries when all indications are that there is no practical solution to mitigate this interference,” said Ken Golden, director of global public relations at John Deere. “In agriculture, the loss of a stable GPS system could have an impact of anywhere from $14 to $30 billion each year. That could significantly erode the strong competitive global position of U.S. farmers in the world agricultural economy.”

Meanwhile, the 2012 agriculture appropriations bill recently passed by the House includes language specifically to register concerns about the LightSquared network and directs the USDA “to ensure the FCC is aware of these concerns.”

Initial reports indicate a proposed high-speed wireless broadband network would interfere with global positioning systems around the country, including those used for precision farming.

Virginia-based company LightSquared wants to set up 40,000 wireless broad-band stations across the nation on a frequency that is right next to the one used by GPS. After concerns were voiced about possible interference, the Federal Communications Commission had the company investigate the possibility and report back to them. Preliminary findings from that report released yesterday indicate there may indeed be a problem. Company officials acknowledge that the tests show the technology could interfere with other signals at certain frequencies and power levels but they believe adjustments could be made to address that. LightSquared has been given another two weeks to present final findings to the FCC.

Opposition to the plan has become organized in the form of the Coalition to Save Our GPS, which consists of a wide variety of industries and companies, including agricultural interests and technology providers such as New Holland, Deere, GROWMARK, Leica Geosystems and Trimble Navigation.

Look up in the sky! It’s a bird! It’s a plane! No, it’s a Multi-Rotor Remote Sensing System!

Somehow Multi-Rotor Remote Sensing System (MRRSS) just doesn’t have quite the same ring as Superman, but these tiny remote-controlled, camera-equipped drones could give some farmers super powers to see their crops from a bird’s eye view. University researchers from Arkansas, Florida and Ohio are currently studying the applications of the system which consists of a six- to eight-rotor, remotely controlled helicopter that provides a stable platform for the off-the-shelf digital camera that sends back video and stills to the ground crew. The system includes image recognition software that can teach itself to recognize individual trees or plants and count them. With different sensors, the machine could potentially detect disease, irrigation or fertilizer issues, predict crop yields and more.

The idea for the system came from Reza Ehsani, Assistant Professor and Precision Agriculture Specialist with the University of Florida’s Citrus Research and Education Center. It’s powered by a lithium ion polymer battery and a basic unit costs from $7,000 to $10,000. Ehsani says it would be a great tool for citrus growers to use to combat citrus greening.

Arkansas researchers are interested in how the system could help row crop farmers and the project in that state is being funded partially by the state soybean board. In Oregon, nurseries and tree farms have the most interest.
