Název v původním jazyce

A computationally efficient approach for estimating high-rate satellite clock corrections in realtime

Popis výsledku v původním jazyce

Satellite clocks are essential element in providing real-time global precise positioning services. Usually these are estimated using zero-differenced phase and range observations of a global network. A large number of ambiguities need to be estimated, thus current estimating sampling interval limits are usually about 5 seconds. New approach was introduced in this paper for fast and efficient clock estimation in real-time where epoch-differenced phase and zero-differenced range observations are used together to estimate epoch-differenced satellite clocks and initial clock bias for each satellite and receiver. A high efficiency of the new approach demonstrated that there is no more problem to estimate clocks every second using the network of one hundredstations, while the quality of estimated clocks are comparable to the that of standard zero-difference technique.
