The Global Navigation Satellite System (GNSS) includes constellations of GPS, Galileo, Beidou and GLONASS systems. It provides continuous radio navigation signals with global coverage of the Earth surface and space volume around it. The availability of navigation satellite signals and estimation of positioning accuracy for space volume located higher than 3000 km is proposed to analyze with the help of simulation. The developed in MatLab model is based on algorithms published in Interface Control Document corresponding satellite system and uses current common GNSS almanac converted in Yuma-format. The simulation scenario optionally takes in account the variety of geometrical restrictions caused by form or transmitting antenna pattern and shadowing of satellites signals by planet profile. Availability of GNSS satellites is simulated for points ranged from ground level up to 36000 km that corresponds to height of geostationary satellites. Results of simulation presented in 3D graphical view and table form. The future scope of research proposes to include calculation of signal level in receiving point as one more critical parameter for user equipment.
