satellite navigation systems - Opis:
- The use of satellite navigation by aerial craft becomes more and more common. Practically every newly produced plane or helicopter has GPS receiver installed on board. This system becomes widely used because it is simple and highly reliable. To improve the Required Performance Navigation Parameters (RNP), namely, the accuracy, availability, continuity, and integrity of aircraft navigation, the integrated GPS and GLONASS techniques can be used. Users are especially interested in integrated GPS/GLONASS receivers. The appearance of new ASHTECH GG24 receiver on the market has made it possible to estimate the possibility of utilisation of this type of receivers in aircraft navigation. The main goal of performed flight trials was the use of those receivers in satellite-based approaches and landings. The authors of the report carried out an experiment aiming at data collection during flight and approach to landing of plane TS11 Iskra. The airport of Deblin was chosen as the test area. The precise trajectory of the aircraft was calculated in the global WGS'84 system of co-ordinates for subsequent positions during flight, at one-second intervals, with the use of RTK techniques in "post-processing" mode. The RTK positions were compared with DGPS/DGLONASS real-time positions and next, the estimation of real-time differential accuracy was done. The preliminary results of the accuracy analysis are given in the paper.
