float solution,ambiguity-fixing PPP,real-time PPP and multi-GNSS PPP were intensively analyzed and discussed.Typical PPP applications were summarized and demonstrated.Finally,we illustrated the prospect of PPP and pointed out problems to be solved for PPP development and applications in the coming ...
Subcarrier modulated signals are widely used in the new generation of Global Navigation Satellite Systems (GNSS) to improve spectral compatibility and ranging accuracy. The unique structure of subcarrier modulated signals poses an ambiguity threat to acquisition and tracking, rendering traditional GNSS sig...
Stable and reliable high-precision satellite orbit products are the prerequisites for the positioning services with high performance. In general, the positioning accuracy depends strongly on the quality of satellite orbit and clock products, especially f

GNNS-R measures multiple points over the ocean to estimate the OSW speed, and its geometry is not like a swath, individual point, or limited to the nadir direction [91]. In contrast to traditional OSW speed retrieval methods, GNSS-R has better spatiotemporal sampling due to the global ...
