Foreword

GB/T 39517 "Agricultural Tractor and Machinery Agricultural Positioning and Navigation System Test Regulations" is divided into the following two parts.

---Part 1.Dynamic test of satellite positioning device;

---Part 2.Testing of the satellite automatic navigation system in straight and horizontal operation.

This part is Part 2 of GB/T 39517.

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

The translation method used in this section is equivalent to ISO 12188-2.2012 "Agricultural Tractor and Machinery Agricultural Positioning and Navigation System Test Regulations"

The second part of the process. the test of the satellite automatic navigation system in the straight and horizontal operation state.

This part was proposed by China Machinery Industry Federation.

This part is under the jurisdiction of the National Agricultural Machinery Standardization Technical Committee (SAC/TC201).
