The Multipath Invariance Approach for Code Multipath Mitigation
Multipath Invariance Approach Code Multipath Mitigation
2015/6/29
The concept of multipath invariance asserts that there exist properties and/or regions of the code correlation function that do not change as a function of the multipath amplitude, delay, phase and ph...
Adaptive Carrier Smoothing Using Code and Carrier Divergence
Adaptive Carrier Smoothing Carrier Divergence
2015/6/25
This paper investigates an adaptive carrier smoothing for a single frequency GPS user. Using a Hatch filter in a single frequency receiver reduces multipath and receiver noise but introduces an induce...
Sensitivity of Code Tracking Methods to PRN Differences
Sensitivity Tracking Methods PRN Differences
2015/6/25
Many of the future GNSS ranging codes produce correlation functions that have two or more prominent sidelobes immediately adjacent to the primary peak. These more complex code modulations have inspire...
Measuring Code-Phase Differences due to Inter-Satellite Hardware Differences
Measuring Code-Phase Differences due Inter-Satellite Hardware Differences
2015/6/24
This paper focuses on the hardware demonstration of pseudorange domain errors from nominal signal deformation, as seen at the output of actual hardware receivers.
Joint L-/C-Band Code and Carrier Phase Linear Combinations for Galileo
Joint L-/C-Band Code Carrier Phase Linear Combinations Galileo
2009/9/3
Linear code combinations have been considered for suppressing the ionospheric error. In the L-band, this leads to an increased noise floor. In a combined L- and C-band (5010–5030 MHz) approach, ...
