Qianshun Chang,Jing Xu,Weicheng Wangtem (GNSS). The four major GNSSs have been equipped with ISLs or plan to equip in near future. Narrow beam inter-satellite link in a time-division multiple access (TDMA) system have advantages of fast beam switching, flexible networking, high communication speed, and good security. For navigation co

Jian-Feng Cai,Raymond Chan,Benedetta Moriniimprove the diversity of available satellites’ geometric distribution and reduce the correlation of observation data by deploying the Low Earth Orbit (LEO) constellations in addition to the medium and high-orbit satellites. The prerequisite is to get the precise orbit products of all these orbiting

Jan Hubený,Pavel Matula,Petr Matula,Michal Kozubek, the periodic characteristics of satellite clocks are analyzed, and using precise SCB data of BDS/GPS satellite the prediction tests are conducted, and then we build the forecast model considering periodic items. Based on this, the influence of the number of periodic items on the result of SCB pred

The direct and reflected signals will be mixed by omni-directional geodetic GPS antenna and the interference patterns of the both signals are recorded in signal-to-noise ratio (SNR) data. The SNR metrics, which refer to the phase, amplitude a

Bias inconsistencies will lead to adverse effects for pseudo-range-based positioning applications and can also hi
