In recent years, the further establishment of the Global Navigation Satellite System (GNSS) has provided good data support for the study of GNSS spatial environmental science. The ionospheric features can be studied by calculating th

Based on this, this paper puts forward a dynamic scheduling strategy of dual-frequency message with fixed time sequence, which makes full use of dual-frequency ranging error change identifier (DFRECI) to repre

In the case of limited constellation scale, it is difficult to achieve more than four-fold coverage, thus the traditional multi-satellite ranging and
