Book
Global Positioning System: Theory and Applications, Volume II
TL;DR: Volume I: GPS Fundamentals Introduction and Heritage and History of NAVSTAR, the Global Positioning System Overview of the GPS Operation and Design GPS Signal Structure and Theoretical Performance GPS Navigation Data Satellite Constellation and Geometric Dilution.
Journal ArticleDOI
Autonomous GPS Integrity Monitoring Using the Pseudorange Residual
TL;DR: This paper describes a method for autonomous GPS satellite failure detection and isolation (D/I) and presents results of applying the algorithm to measurement sets containing a biased measurement.
Journal ArticleDOI
Modified sidereal filtering: Implications for high‐rate GPS positioning
TL;DR: In this article, the GPS orbital repeat period was investigated and it was determined that it varies for each satellite and differs significantly from the generally assumed sidereal period, and the calculated orbit repeat period significantly reduced low frequency (0.001-0.04 Hz) errors in 1-Hz GPS position estimates.
Journal ArticleDOI
Using GPS multipath to measure soil moisture fluctuations: initial results
TL;DR: In this paper, a methodology is described that uses existing networks of continuously operating GPS receivers to measure soil moisture fluctuations, where incoming signals are reflected off and attenuated by the ground before reception by the GPS receiver.
Journal ArticleDOI
Initial results of land-reflected GPS bistatic radar measurements in SMEX02
TL;DR: In this article, a prototype GPS bistatic radar participated in airborne measurements during the Soil Moisture Experiment 2002 (SMEX02) and was mounted on the NCAR C-130 aircraft to make co-located measurements with other instruments.
