PDOP parameters improvement using multi-GNSS and signal re-transmission at lunar distances

Popis výsledku v původním jazyce

Precise navigation for satellites of any kind is the key to future cost-effective Lunar missions. The usability of Global Navigation Satellite Systems (GNSS) for such high-altitude applications is still challenging due to reduced signal power levels, satellites visibility or signal processing complexity with all that resulting in a low position, velocity and time (PVT) accuracy, which is typically expressed by geometric dilution of precision (GDOP) parameters. This paper proposes a navigation method based on re-transmission combined with multi-GNSS concept, specifically signal reception from GPS, Galileo, Glonass, BeiDou and SBAS satellites’ antenna pattern main-lobes and side-lobes. Those signals are re-transmitted from the user satellite at the Lunar distance to the Earth, where all the signal processing is assumed to be performed. Based on the results from the tests of the of modelled scenario, the method presents an improvement of the position dilution of precision (PDOP, a subset of GDOP) parameters for the missions at the Lunar distance.
