Locations generated by localisation systems based on Global Navigation Satellite System (GNSS) need to be evaluated for certification purposes. This paper describes the basis of a certification methodology for GNSS receivers by means of reliability evaluation. The proposed reliability evaluation of GNSS receiver is based on the appropriate precision levels of collected locations. The precision levels are determined through a throughout accuracy evaluation which provides the standard deviation (σ) of the locations in advance. Then reliability is assured by the comparison between nσ and the reliability requirements for the corresponding application. Three separated evaluations constitute the presented process: evaluation of reliability for static GNSS receiver location data; evaluation of the reliability for dynamic GNSS receiver location data and evaluation of the receiver’s acquisition time from cold start, warm start and hot start. The reliability report is derived from these evaluations results. This process is attested in order to obtain the certification. The presented certification approach allows further development on GNSS receiver’s quality functions for certification.
