Study of inter-system biases(ISB) is essential for the data processing of multi-constellation precise point positioning(PPP). When establishing BDS/GPS short-term ISB models, as equal-weight least square(LS) fails in taking the different weights of f

Carrying out the calibrate by placing the ball on the sea has some disadvantages, such as high cost, low efficiency, etc. Based on this point, a maritime calibration method based on fixed-wing UAV is proposed. Firstly, choosing the appropriate UAV mo

Receiver antenna phase center bias is a source of error must be considered in precise orbit determination using GPS. And PCV generally need multi-day observations data for joint estimation, so the estimation methods and its efficiency are particularl

In the traditional time transfer algorithms of precise point positioning, the receiver clock offset is estimated epoch by epoch as independent white noise and the short-term correlation between the epoch of the atomic clock offset is ignored. In orde

Multi-days orbit of BeiDou satellites is gotten by the routine method of stacking observation data at present, which limits calculation efficiency. And moreover, the dynamic model of BeiDou satellites is not perfect because of the short running time,

Ionospheric delay correction is the core issue of LEO satellite single-frequency precise orbit determination. At present, "the method of ionosphere scale factor" is mainly adopted in the LEO satellite ionospheric delay correction, but the method does
