Each member body interested in a subject for which a technical committee has been established has the right to be rep

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards ar

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internationa
14、l Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

17、nformation for the dynamic testing of satellite based positioning devices or complex navigation systems (automatic steering systems) used in agriculture. The dynamic testing relies on metering geographic positioning quality when tested devices and systems are in motion resembling their use in agricu

Potential users include developers and manufacturers of agricultural equipment and positioning or navigation components as well as farmers or other end users.

20、e ISO 12188 specifies the process for evaluating and reporting the performance of agricultural vehicles equipped with automated guidance systems (AGS) based on a global navigation satellite system (GNSS) when operating in an automatic steering mode.The main performance criterion is the lateral devia
21、tion of a representative point on the vehicle from a desired trajectory for that point. This performance criterion integrates the uncertainties associated with the performance of all components of the vehicle guidance system including the positioning device(s), automated steering components, and veh
22、icle mechanisms and dynamics.This part of ISO 12188 focuses on steady-state tracking performance of the automated guidance system while travelling on straight paths over a level surface.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1 General te
