Abstract. The article considers an integrated approach to flight testing of on-board radio navigation and landing equipment, which is determined by the widespread usage of information and measurement systems, automation of processing flight test data combining methods and means of processing and analyzing various equipment into a unified technological cycle. The application of GNSS-based trajectory measurement tools for the characteristics evaluation of on-board equipment is described. Examples of error estimates for the on-board equipment of the ILS, VOR/DME, and a low-altitude radio altimeter are given.

Keywords: flight tests, radio navigation and landing equipment, Doppler navigation system, radio altimeter, error estimation, trajectory measurement, global navigation satellite system
