Procedure for GNSS equipment verification in static positioning

GNSS static positioning is the premier method for numerous surveying applications requiring high precision. Many countries have developed national guidelines to specify the minimum requirements for the best practise and statistical evaluation for static GNSS surveying, but there is still missing a uniform standard that can be adopted by the surveyors to assess their equipment prior to any surveying task. This paper aims to describe a guideline that promotes uniform procedures for equipment verification and data assessment in order to achieve the highest level of integrity for routine surveying applications. The guideline refers to field practise and statistical evaluation of the measured data using the local and the global tests. The former is an evaluation procedure performed on individual survey measurements, e.g. baseline, in order to assess the quality of a measurement and its assumed uncertainty at a statistical level. The latter is an evaluation procedure performed to assess the quality of the survey, such as a network, as a hole. Results from a number of field tests are given using different types of geodetic receivers.
