Optics and optical instruments — Field procedures for testing geodetic and surveying instruments — Part 11: GNSS instruments

Description

This document specifies a field procedure for the verification that a given Global Navigation Satellite System (GNSS)-based system and measurement procedure meets a required measurement uncertainty at the location and time of interest.

The field procedure uses three-dimensional coordinates which are compared to reference coordinates. It is designed to be applicable to the technically versatile geodetic and surveying GNSS systems on the market and can be used for any kind of GNSS-based applications to determine coordinates. It is independent of the technology used in the GNSS measuring instrument, the satellite data streams, and any correction data used.

The procedure is applicable to GNSS instruments under operating condition in the field in such a way that the main parameters affecting the determination of coordinates are included in the result of the test. This document defines several delimitation criteria, which allows for versatile applicability. As a result, the verification procedure can be regularly performed in the field with limited economic impact.

Abstract

This document specifies a field procedure for the verification that a given Global Navigation Satellite System (GNSS)-based system and measurement procedure meets a required measurement uncertainty at the location and time of interest.

The field procedure uses three-dimensional coordinates which are compared to reference coordinates. It is designed to be applicable to the technically versatile geodetic and surveying GNSS systems on the market and can be used for any kind of GNSS-based applications to determine coordinates. It is independent of the technology used in the GNSS measuring instrument, the satellite data streams, and any correction data used.

The procedure is applicable to GNSS instruments under operating condition in the field in such a way that the main parameters affecting the determination of coordinates are included in the result of the test. This document defines several delimitation criteria, which allows for versatile applicability. As a result, the verification procedure can be regularly performed in the field with limited economic impact.
