Relative Positioning with RTK Filtering and PPP FILLING THE GAPS

Analysing the Zenith Tropospheric Delay Estimates in On-line Precise Point Positioning (PPP) Services and PPP Software Packages

As Global Navigation Satellite System (GNSS) signals travel through the troposphere, a tropospheric delay occurs due to a change in the refractive index of the medium. The Precise Point Positioning (PPP) technique can achieve centimeter/millimeter positioning accuracy with only one GNSS receiver. The Zenith Tropospheric Delay (ZTD) is estimated alongside with the position unknowns in PPP. Estim...

Survey on Resource Positioning

In the last decade, positioning has become a steadily growing research topic. The increase in use and availability of wireless networks has allowed for an ever growing exchange of information and increased communication capabilities. Mobile applications offer resource positioning, which can help in different areas of society. These applications can be used to track people with special needs or ...

Distribution of Rational Points: A Survey

Real-time Kinematic Positioning of INS Tightly Aided Multi-GNSS Ionospheric Constrained PPP

Real-time Precise Point Positioning (PPP) technique is being widely applied for providing precise positioning services with the significant improvement on satellite precise products accuracy. With the rapid development of the multi-constellation Global Navigation Satellite Systems (multi-GNSS), currently, about 80 navigation satellites are operational in orbit. Obviously, PPP performance is dra...
