Precision agriculture relies on autonomous farm machinery with high-precision navigation to optimize seeding, fertilizing, and harvesting. A European agricultural machinery manufacturer developing autonomous tractors and planters faced challenges with positioning accuracy and environmental durability, leading them to partner with Tengxiang Electronics—a national high-tech enterprise specializing in GNSS antenna solutions.

Client Background

The client is a leading manufacturer of agricultural machinery in Europe, supplying equipment to farms across the continent. Their autonomous planters required a high-precision GNSS RTK antenna to achieve centimeter-level seeding accuracy, with resistance to extreme farm environments.

Core Pain Points

1. Positioning Inaccuracy: Traditional antennas failed to achieve consistent centimeter-level precision, leading to uneven seeding and wasted resources.

2. Environmental Vulnerability: Farm environments (mud, rain, extreme temperatures) damaged standard antennas, causing frequent equipment downtime.

3. High Power Consumption: Existing antennas consumed excessive energy, shortening the machinerys battery life and operational time.

4. Mounting Challenges: The antenna needed to be mounted on the machinerys roof without being damaged by crops or debris.

Tengxiangs Custom Solution

Drawing on our expertise in high-precision GNSS antennas and extreme environment adaptation, Tengxiang developed a tailored RTK antenna solution:

1. High-Precision Positioning: Integrated multi-satellite (GPS/BeiDou/GLONASS/Galileo) compatibility and advanced RTK technology, achieving 2cm seeding precision.

2. Extreme Environment Protection: Equipped the antenna with IP67 waterproof and dustproof rating, resistant to temperatures ranging from -40℃ to 70℃. The casing was made of impact-resistant material to withstand debris and crop contact.

3. Low Power Optimization: Adopted energy-efficient components and standby mode technology, reducing working current to less than 5mA—extending the machinerys battery life by 20%.

4. Custom Mounting Design: Developed a low-profile, aerodynamic mounting bracket to secure the antenna on the machinerys roof, minimizing crop damage and wind resistance.

Implementation & Testing

Tengxiangs R&D team collaborated with the clients engineering department to optimize the antenna for their autonomous planters. Field tests were conducted in corn and wheat fields across Germany and France, verifying the antennas positioning accuracy and durability.

The antenna also underwent rigorous laboratory tests, including vibration, impact, thermal shock, and salt spray resistance—all meeting European agricultural machinery standards.

Project Outcomes

Precision Agriculture: The 2cm positioning accuracy enabled uniform seeding, reducing seed waste by 15% and increasing crop yield by 10%.

Durability: Zero antenna failures were reported during 12 months of field use, even in heavy rain, dust, and extreme temperatures.

Extended Operational Time: Low power consumption extended the machinerys battery life by 20%, allowing for all-day farm operations.

Market Expansion: The antenna was integrated into 3 of the clients autonomous machinery models, exported to 5 European countries.
