The purpose of this paper is to statistically derive and compare reliability results of Earth-orbiting satellites as a function of orbit type, namely geosynchronous orbits (GEO), low Earth orbits (LEO) and medium Earth orbits (MEO). Using an extensive database of satellite launches and failures...

(GPS), the Russian Global Navigation Satellite System (GLONASS) and the European Galileo, the developing Chinese BeiDou satellite navigation system (BDS) consists of not only Medium Earth Orbit (MEO), but also Geostationary Orbit (GEO) as well as Inclined Geosynchronous Orbit (IGSO) satellites. ...

With RAFS or Hydrogen maser on GEO/IGSO and MEO satellites, the time stability better than 1ps and accuracy better than 100 ps can be achieved, at least one order of magnitude is better in the optical region than the radiofrequency region. Groundbreaking work has been done in developing ...
MEO satellites is achieved and then the performance of the PPP AR results is evaluated.Results show that:The convergence time and the time to first fix are both less than 30 min for BDS PPP ambiguity resolution with GEO\\IGSO\\MEO satellites.The positioning error based on six-hour ...

According to this index, the MEO environment from IRENE (AP9/AP9/SPM) is much more severe than the GEO environment (which is in turn much more severe than the LEO environment), and should produce more spacecraft arcing. Indeed, RFI detectors on-board GPS satellites show that the rate of...
