Many of us mindlessly shop for food, fuel, clothing, home goods and more without thinking much about where it all comes from, forgetting that in most cases it all started on a farm. Most people are unaware that a key component of agriculture production, besides the soil beneath our feet, is the use of critical technologies such as GPS and other GNSS contstellations. When fully leveraged, technology can be a part of the solution to many of the challenges farmers face today and be a tool in feeding a growing global population.
With technology at their fingertips, farmers across the globe can enhance their productivity through precision agriculture — a practice that uses GNSS technology to maximize agricultural outputs, while reducing farmer inputs and improving sustainability. Precision agriculture is used to till, plant and harvest crops such as corn, soybeans, cotton, peanuts, wheat, tubers and alfalfa. For example, techniques including yield mapping for fertilizer application have been used on fields across the country for more than three decades.
Social and Economic Benefits of Precision Agriculture
According to the U.S. Department of Agriculture (USDA), total U.S. farm output tripled from 1948 to 2021 largely due to advancements in technology — even as farm labor, land and other inputs declined. Farmers needed 8 million fewer acres to produce the same wheat yields in 2018 as in 1990, according to an American Farm Bureau Federation report.
A closer look at four crops commonly tilled, planted and harvested using precision agriculture techniques highlight technology’s economic benefits:
- Sweet Corn: The United States is the largest producer of sweet corn at roughly 315 million tons per year, accounting for 34% of global production. There are more than 316,000 U.S. corn farms, 95% of which are family-owned. In 2021, Florida was the largest producer of sweet corn, followed by California, Washington and Michigan. The United States exports 69 million tons of sweet corn annually, yielding a value totaling $9.2 billion. China is the largest buyer of U.S. sweet corn, purchasing 31% of all U.S. exports.
- Peanuts: In 2023, the United States produced roughly $1.6 billion in peanuts, led by Georgia — with 55% of total U.S. peanut production — followed by Texas (10%), Alabama (10%), and Florida (9%). In 2023, the United States exported more than $889.5 million worth of peanuts, with Mexico and Canada as top destinations. With new techniques to adjust digger conveyor speeds, yield continues to improve.
- Cotton: The United States produces roughly 15 million bales of cotton each year, contributing to a $21 billion industry. Texas boasts the highest number of planted acres with 40% of the U.S. supply (6 million bales), followed by Georgia at about 2.5 million bales. The United States is the world’s leading exporter of cotton, totaling 35% of the total global supply. Farmers are increasingly using autosteer technology to help grow and harvest cotton — with the adoption of precision agriculture equipment jumping from 46% in 2008 to 86% in 2023, according to a survey conducted by Cotton Grower.
- Wheat: The United States produces roughly 7% of the global wheat supply — accounting for roughly $12.7 billion — with Kansas, North Dakota, Montana, Texas and Oklahoma producing the most wheat across the country.
Precision agriculture also helps farmers work toward important conservation goals. Auto guidance capabilities and seeding sensors increase tractor and seeding efficiencies, reducing herbicide use by 9% and fossil fuel use by 6%. These small but important changes contribute to a wider effort to employ more sustainable agriculture practices, with precision agriculture and GPS technology sitting front and center.
Through it all, GNSS remains at the forefront of a strong, efficient agriculture system. Whether it’s auto-steering tractor technology or strengthened hydrology practices, new precision agriculture technologies are released every year. If broader adoption of precision agriculture technologies continues, the United States can increase its national crop production by 6%, bolstering the agriculture economy even further.

GPS and GPSIA in the Field
GPS Innovation Alliance (GPSIA) members Deere & Company and Trimble are at the forefront of advancing precision agriculture techniques globally, creating more opportunities for farmers to boost their productivity and reduce crop loss with innovative GPS and GNSS technologies.
Deere & Company offers several receivers that use GNSS technology to plant crops with accuracy down to the centimeter and coupled with the sensors and computer vision, allow farmers to plant at quicker speeds without damaging crops — including its fully autonomous 8R tractor unveiled in 2022. While Deere & Company had been developing new GNSS receivers for years, a critical partnership with NASA’s Jet Propulsion Laboratory (JPL) in 2004 was groundbreaking. Deere & Company modified its GNSS receivers to tap into the agency’s network of ground stations and incorporated JPL’s software. The innovation allowed them to introduce autonomous tractors worldwide, revolutionizing precision agriculture and leading to a wider acceptance of autonomous tractor technology.
Trimble has brought innovative solutions to precision agriculture since the company first began producing its agricultural GPS receivers in 1997. Since then, the company has unveiled state-of-the-art technologies to support farmers, including RTX technology which uses precise point positioning (PPP) to allow farmers to plant seeds and farm with sub-inch GNSS accuracy. Trimble also has announced several partnerships that strengthen the company’s precision agriculture capabilities from CNH and CLAAS (2011) to Horsch (2021) to AGCO (2023).
In 2022, Trimble deepened its partnership with agricultural machinery manufacturer CLAAS to integrate Trimble’s GPS PILOT system and SAT 900 GNSS receiver with CLAAS’ CEMIS 1200 display, providing farmers greater accuracy when tilling, seeding, spraying, or harvesting their fields. In April 2024, Trimble created a joint venture with AGCO to accelerate the pace of innovation and increase farmer’s access to precision agriculture technology.
Critical Role of Broadband in Precision Agriculture
Reliable broadband connectivity goes hand-in-hand with GNSS technologies and allows full use of agriculture technology and its resulting benefits. According to the USDA, more than 20% of rural households and farms do not have reliable access to broadband, limiting access to new technologies that would enhance efficiency and help farmers grow their businesses.
Industry leaders are working to ensure that farms across the country can reliably access the Internet. For example, Deere & Company, in partnership with SpaceX, is working to close the connectivity gap among farmers with satellite communications (SATCOM) services. Later this year, Deere & Company will begin to offer Starlink satellite communications technology to farmers across the United States and Brazil.
Beyond industry investment, the USDA’s Rural Development Broadband ReConnect Program provides grants and loans to strengthen broadband infrastructure and equipment in eligible rural areas. In addition, the National Telecommunications and Information Administration is overseeing the $42.5 billion Broadband Equity, Access, and Deployment program, intended to expand high-speed Internet access for communities across the country with little to no Internet connectivity. Establishing tech-neutral policies within these and similar programs as well as focusing on delivering coverage to uncovered agriculture lands to the last acre is key to improving efficient agriculture production.
Precision Ag on the Hill
Precision agriculture is also making its way into policy conversations at all levels of government as awareness around agriculture technology and its benefits are realized.
The 2018 Farm Bill established the Task Force for Reviewing the Connectivity and Technology Needs of Precision Agriculture in the United States (“Precision Ag Connectivity Task Force”) within the Federal Communications Commission. The Task Force is currently completing its third and final term this year and will have produced three comprehensive reports with related recommendations for policymakers.
The 2018 Farm Bill expired on Sept. 30, 2023, but was extended for one year to allow the U.S. Congress additional time to come to agreement on the next five-year reauthorization bill. The Farm Bill presents a key bipartisan legislative opportunity to include incentives for agriculture technology adoption. Lawmakers should consider previously introduced standalone legislation, including the PRECISE Act and the PAL Act, to accomplish this goal. Together, these bills would expand existing USDA programs to include precision agriculture technologies and create a new loan program.
Small family farms account for roughly 88% of all farms in the United States but make up less than 20% of all U.S. agricultural products sold. To increase yields and better compete with large-scale farms, farmers are increasingly turning to precision agriculture technologies — though availability remains a challenge. Understanding these statistics, efforts to promote equal access to precision agriculture enjoy bipartisan support from both chambers of Congress.
Reflection
GNSS technology’s role in precision agriculture continues to save farmers time and money, while simultaneously providing conservation-oriented solutions for farmers, consumers and the planet. GPSIA members Deere & Company and Trimble have contributed innovative solutions to precision agriculture technology for decades, enhancing efficiencies through groundbreaking partnerships and expanding opportunities for farmers to use the technology. These innovations, coupled with recent rural broadband expansion efforts, ensure farmers can access the most cutting-edge technology and continue to innovate. The focus on precision agriculture on Capitol Hill is an important reminder of the wider implications of GNSS in our everyday lives and how GNSS systems fit into the U.S. agriculture industry. GPSIA is proud to support its members as they continue to promote the use of innovative GNSS technologies in agriculture.
