Ground-based correction data service for satellite positioning

Subject of audit:

This certification mark is awarded to a ground-based correction data service for satellite positioning allowing real-time positioning up to an accuracy of ±2cm. Verification subjects are real-time positioning accuracy, availability and quality of the service for in-motion farming applications.

Examination based on:

The certification mark is awarded within the framework of voluntary testing and certification. The statistical evaluation of the dynamic trials is based on:

  • ISO 5725-2:1994 - Accuracy (trueness and precision) of measurement methods and results - Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method

The verification of the service is conducted very similar to PPP80013. Testing focuses on:

  • Validation and verificaton of the (management) concepts for
    • System Design
    • User Management
    • Data Processing
    • Data Security
    • Trouble-shooting and fault rectification
  • Analysis of availability and operational reliability
  • Measurement of performance and accuracy in accordance to ISO 5725-2
    • By using a test course reflecting the requirements in agriculture (slow speeds, cornering and turning manoeuvres) and a high-precision reference measurement system (GPS positioning system + RTK base station + high precision inertial sensors)
    • Statistical evaluation
  • Service Quality
    • Response time to customer inquiries
    • Technical Expertise

Test mark affirms:

1. Precision farming:
Precision farming (PF) refers to site-specific and targeted management of farming areas. Precision farming is designed to consider the differences in soil and yield potential within a field. The machinery and equipment needed for precision farming in a field generally use (sensor-controlled) navigation systems and GNSS receivers as well as special equipment for demand-oriented site-specific application of growth regulators. Certification of the system to be tested verifies that PF satisfies the requirements regarding availability, reliability and accuracy of the correction data.

2. Guidance Systems:
Guidance systems are DGNSS-based equipment enabling users to drive equally spaced straight (parallel) tracks, curves or circles. They help to prevent skips and overlap and thus reduce material consumption. A guidance system makes high demands on the precision and reliability of a DGNSS system.

3. 2 cm Dynamic Accuracy:
Refers to the accuracy shown by the system to be tested in comparison to the reference system (GNSS positioning system + RTK base). This accuracy is an important criterion for precision farming and guidance systems.
