This is the 33th annual review of the application of atomic spectrometry to the chemical
analysis of environmental samples. This update refers to papers published approximately …

Multipath is one of the critical constraints in millimeter-level BeiDou navigation satellite
system (BDS) positioning. Since multipath hemispherical map (MHM) can be conducted in …

The latest generation of GPS satellites, termed Block IIF, provides a new L5 signal. Multi-
frequency signals open new prospects for precise positioning and fast ambiguity resolution …

Significant time-varying inter-frequency clock biases (IFCBs) within GPS observations
prevent the application of the legacy L1/L2 ionosphere-free clock products on L5 signals …

Since 2015, China has successfully launched five experimental BeiDou global navigation
system (BDS-3) satellites for expanding the regional system to global coverage. An initial …

The time-varying biases within carrier phase observations will be integrated with satellite
clock offset parameters in the precise clock estimation. The inconsistency among signal …

The carrier-phase (CP) technique based on the Global Navigation Satellite System (GNSS)
has proved to be a useful spatial tool for remote and precise time transfer. In order to …

Multipath is one of the major source of errors in precise Global Navigation Satellite System
positioning. With the emergence of new navigation systems, such as Galileo, upgraded …

The pseudorange observation of the BeiDou satellite navigation system (BDS) reveals some
special errors. Except for the elevation-dependent code bias variations, we present receiver …
