Real-Time Precise Point Positioning Using Single Frequency Data

  title={Real-Time Precise Point Positioning Using Single Frequency Data},
  author={Kongzhe Chen and Y. Gao},
Precise Point Positioning (PPP) has begun to receive increased interests within the GPS community for a number of reasons: simplified operation, cost-effective and no base stations required. PPP with dual-frequency receivers and precise GPS products have demonstrated centimeter to decimeter positioning accuracy (Zumberge et al., 1997; Kouba and Heroux, 2001, Gao and Shen, 2002). Using real-time GPS products, the accuracy is also obtainable in real-time (Chen, 2004). This paper investigates PPP… Expand
