TL;DR: This work presents an ambiguity resolution algorithm that improves solution accuracy for single receiver point-positioning users and constrain (rather than fix) linear combinations of local phase biases to improve compatibility with global phase bias estimates.

TL;DR: In this paper, the authors describe a system that was developed at the Jet Propulsion Laboratory and used to process the GPS/MET data and compared to analyses from the European Center for Medium-range Weather Forecast (ECMWF).

TL;DR: In this paper, radio occultation measurements using Global Positioning System satellite transmitters and an orbiting receiver have provided a globally distributed set of high-resolution atmospheric profiles, suggesting that the technique may make a significant contribution to global change and weather prediction programs.

TL;DR: A reduced dynamic filtering strategy that exploits the unique geometric strength of the Global Positioning System to minimize the effects of force model errors has yielded orbit solutions for TOPEX/POSEIDON which appear accurate to better than 3 cm (1 σ) in the radial component.

TL;DR: In this article, baseline lengths and geocentric radii have been determined from GPS data without the use of fiducial sites and the geodetic information can be obtained by examining the structure of the polyhedron and its change with time.
