TLDR
The next generation of positioning models for positioning and data processing will depend on the design of the satellite itself, as well as on the satellite orbits it is placed in.Citations

Characterization of between-receiver GPS-Galileo inter-system biases and their effect on mixed ambiguity resolution
Dennis Odijk,Peter Teunissen +1 more
TL;DR: The mixed GPS + Galileo model that is based on “inter-system” double differencing, that is, differences the Galileo phase and code observations relative to those corresponding to the reference or pivot satellite of GPS, is derived.

On the estimability of parameters in undifferenced, uncombined GNSS network and PPP-RTK user models by means of S-system theory
Dennis Odijk,Baocheng Zhang,Amir Khodabandeh,Robert Odolinski,Robert Odolinski,Peter Teunissen,Peter Teunissen +6 more
TL;DR: In this article, the authors present a method for PPP-RTK that is based on the undifferenced, uncombined GNSS observation equations, thereby keeping all parameters in the model, including the essential ambiguity parameters, which have the integer property which is clearly following from the interpretation of satellite phase biases from the network.

Physical applications of GPS geodesy: a review.
TL;DR: The relevant concepts of geodetic theory, data analysis, and physical modeling for a myriad of processes at multiple spatial and temporal scales are reviewed, including the extensive global infrastructure that has been built to support GPS geodesy consisting of thousands of continuously operating stations.

Integer Least-squares Theory for the GNSS Compass
Peter Teunissen,Peter Teunissen +1 more
TL;DR: In this paper, a nonlinear baseline constraint is fully integrated into the ambiguity objective function, thereby receiving a proper weighting in its minimization and providing guidance for the integer search, and different search strategies are developed to compute exact and approximate solutions of the nonlinear constrained ILS problem.

Geodetic imaging with airborne LiDAR: the Earth's surface revealed
TL;DR: This paper traces nearly a half century of advances in geodetic science made possible by space age technology, such as the invention of short-p Pulse-length high-pulse-rate lasers, solid state inertial measurement units, chip-based high speed electronics and the GPS satellite navigation system, that today make it possible to map hundreds of square kilometers of terrain in hours.
