GNSS Performance Research for MEO, GEO, and HEONSS and multi-GNSS choice for most of the six space users while a Beidou-only receiver performs the best for GEO1 satellite which is fixed above the Asia-Pacific area. It can be concluded that for the space users below 50,000 km, it is possible to attain an average PDOP of below 20 with a receiver s

A Study on the Orbit Accuracy Variation Characteristics and Yaw-Attitude Modes of Beidou Navigation 16 and adopt a modified yaw-attitude mode during its eclipse season, and found that the orbit accuracy of BDS IGSO-6 satellite is better than 0.25 m, no obvious orbit accuracy decrease can be observed, which is inconsistent with that of previous IGSO satellites. However, the performances of precise

Design of Deorbit Parameters for BEIDOU MEO and IGSO Satellites Based on Long-Term Eccentricity Evolin the BEIDOU navigation constellation studied. Designing the deorbit parameters to reduce their orbital lifetime or make sure that the perigee of disposal orbit is not below the protected region in 100 years. The simulation results show that the deorbit parameters are reasonable and meet the requir
