Mitigating systematic errors for single frequency GPS receivers employing a penalized least squares methodology
Among the positioning systems that compose GNSS (Global Navigation Satellite System), GPS has the capability of providing low, medium and high precision positioning data. However, GPS observables may be subject to many ...

GPS Diffractive Reflectometry: Footprint of a Coherent Radio Reflection Inferred From the Sensitivity Kernel of Multipath SNR
(Ieee-inst Electrical Electronics Engineers Inc, 2016-10-01)
The validation of remote sensing environmental estimates requires knowledge of their spatial extent and resolution. Here, we consider coherent radio reflections routinely observed in ground-based global positioning system ...
Using cubic splines to mitigate systematic errors in GPS relative positioning
Systematic errors can have a significant effect on GPS observable. In medium and long baselines the major systematic error source are the ionosphere and troposphere refraction and the GPS satellites orbit errors. But, in ...
Improving the GNSS positioning stochastic model in the presence of ionospheric scintillation
Ionospheric scintillations are caused by time-varying electron density irregularities in the ionosphere, occurring more often at equatorial and high latitudes. This paper focuses exclusively on experiments undertaken in ...
GPS ambiguity resolution and validation under multipath effects: Improvements using wavelets
Integer carrier phase ambiguity resolution is the key to rapid and high-precision global navigation satellite system (GNSS) positioning and navigation. As important as the integer ambiguity estimation, it is the validation ...
