Standard addresses testing of satellite positioning devices.
Press Release Summary:
ASABE announced publication of international standard that provides procedure for evaluating and reporting accuracy of navigation data determined using positioning devices that are based on GPS, GLONASS, Galileo, or similar global navigation satellite systems. Because satellite positioning devices have become more common in agricultural applications, ISO 12188 focuses on performance of positioning devices while they are subject to motions typical of ground-based agricultural field operations.

New Standard Announced for Testing Satellite-Based Positioning Devices
ST JOSEPH, MICHIGAN - The American Society of Agricultural and Biological Engineers (ASABE) announces the publication of an international standard that provides a procedure for evaluating and reporting the accuracy of navigation data determined using positioning devices that are based on GPS, GLONASS, Galileo or similar global navigation satellite systems.
ISO 12188-1: 2010, "Tractors and machinery for agriculture and forestry -- Test procedures for positioning and guidance systems in agriculture -- Part 1: Dynamic testing of satellite-based positioning devices," was recently published in English and French for international use.
Because satellite positioning devices have become more common in agricultural applications, a need emerged for a standard that would meet the specific needs of agricultural equipment. These devices are not only used as position sensors, but are also part of more complex navigation systems for a variety of agricultural machines.
Previously, the only existing standards for satellite-based, positioning-device performance specification focused on the static accuracy of the device. There was no standard that adequately specified methods for testing or reporting the accuracy of the receivers while they are in motion. This new part of ISO 12188 fills this void by providing a framework for testing receivers that are subject to the type of motion typically experienced by receivers used in agricultural field operations. It provides an implementable methodology for conducting the tests while still providing a means to equitably compare the performance of different satellite-based positioning devices.
This new standard focuses on the performance of the positioning devices while they are subject to motions typical of ground-based agricultural field operations. Specific common performance parameters that can be used to quantify and compare the dynamic performance of different positioning devices are then utilized to document the outcome of the testing.
ASABE is the accredited administrator for the US technical advisory group to the ISO committee on Tractors and Machinery for Agriculture and Forestry (TC23), and seven of its subcommittees. Committee membership is open and typically comprises individuals with an academic or commercial interest in the subject matter. Participation in standards development benefits commerce as well as the public by ensuring issues such as consumer safety and evolving technology are addressed in a thorough and timely manner and by reducing trade barriers that can occur in the absence of standardization.

ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 225 standards of its own currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial, or other governmental requirements. Standards documents are developed by consensus in accordance with procedures approved by the American National Standards Institute.
