Why Precision Agriculture? 

The agricultural industry faces a convergence of pressures that make precision technology not just an advantage, but a necessity. Three interconnected trends are reshaping farming worldwide.

Food Production in a Growing World with Less Land

The world population is projected to reach nearly 10 billion by 2050. Global agricultural land use has already peaked and is now declining, while global agricultural production continues to rise. This decoupling of land use from output is only possible through smarter, more precise farming. Precision positioning is a key enabler of this efficiency.

Precision Farming for a Shrinking and Aging Workforce

The agricultural workforce is facing a structural crisis. According to the International Labour Organization, agriculture accounted for 43% of global employment in 1991. By 2023, that share had fallen to just 26%.

At the same time, the number of farms is in decline and farmers are aging. The global average age of a farmer is now 55 years (World Economic Forum). In the EU, the average age is 57 with only 12% of farmers under the age of 40 (European Commission, 2025).

Autonomous and semi-autonomous farming machines powered by precise GNSS directly address this workforce gap. They enable machines to work precisely, while humans focus on higher-value tasks.

Overcoming the Challenge of Agricultural Sustainability

Global agriculture relies on millions of tons of chemical fertilizers, pesticides, and growth regulators annually to sustain output. The costs are high: Runoff and water pollution, soil degradation, human health risks, and the direct financial costs. Precision technology addresses this trade-off directly. Precise sprayers and drones apply inputs where and when needed, preventing over-application.

精准农业的用例

Understanding GPS and RTK Technology for Precision Agriculture

Standard GNSS positioning delivers 1–2 m horizontal accuracy and 2–4 m vertical accuracy. This is sufficient for asset tracking and basic telematics, but not for precision agriculture. Achieving centimeter-level positioning requires understanding and correcting the sources of error in the satellite signal path.

Sources of GNSS Error

GNSS signals travel through the ionosphere and troposphere on their way from satellite to receiver. Each layer introduces measurement errors. They combine with other sources of error, such as satellite orbit and clock errors, multipath reflections, and receiver noise. Total positioning errors can range from sub-meter to tens of meters in challenging environments.

Correction Technologies: RTK, PPP-RTK, and PPP-AR

Three main correction approaches exist, each offering a different balance of accuracy, convergence time, and required infrastructure:

• RTK (Real-Time Kinematic): Corrects global satellite errors and delivers 1–2 cm accuracy in under 10 seconds. Requires a dense network of local reference stations. Ideal for high-demand applications like construction, surveying, and precision agriculture.
• PPP-RTK (Precise Point Positioning Real-Time Kinematic): Corrects global and regional errors including ionospheric and tropospheric delay. Achieves 3–6 cm accuracy in under 30 seconds. More flexible infrastructure requirements. Suitable for mobile outdoor robotics, automotive, precision agriculture, and UAVs.
• PPP-AR (Precise Point Positioning with Ambiguity Resolution): Global corrections with no local infrastructure needed. Achieves <10 cm accuracy in approximately 2 minutes. Ideal for remote-area applications and global precision agriculture deployments.

The All-Band Advantage

Modern GNSS receivers support all signal bands (L1/L2/L5/L6) and give access to all satellite constellations. This enables faster convergence to centimeter-level accuracy, and more reliable signals.
