Phase-Difference Ambiguity Resolution for a Single-Frequency Signal [PDF]
IEEE Signal Processing Letters, 2008 In this letter, we propose a novel method to disambiguate the phase-difference of a single-frequency signal observed between a pair of spatially separated sensors, with inter-sensor spacing exceeding half the wavelength (lambda/2) of the signal. We mathematically prove that, in a noiseless case, the true phase-difference can unambiguously be estimated ...

BeiDou System (BDS) Triple-Frequency Ambiguity Resolution without Code Measurements
Remote Sensing, 2018 Phase and code measurements achieve ambiguity resolution in medium- or long-baseline computation. However, the code multipath effect on Global Navigation Satellite Systems (GNSS) phase and code measurements is a main source of error for ambiguity ...

A phase ambiguity resolution technique for TCM
MILCOM 92 Conference Record, 2003 The authors present the simulation model, performance evaluation, and hardware implementation of a technique to resolve phase ambiguity in trellis-coded modulation (TCM) where the popular Viterbi algorithm is utilized. While this approach has been used with BPSK (binary phase shift keying) and QPSK (quadrature phase shift keying), its application to ...

Single-Differenced Ambiguity Resolution for Orbit Determination of the Haiyang-2B
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 In ambiguity resolution, the Hatch–Melbourne–Wübbena code and carrier phase combination is usually used to fix the wide-lane (WL) ambiguity, and thus, the quality of the code observations directly affects the fixing success rate ...

Theory of carrier phase ambiguity resolution [PDF]
Wuhan University Journal of Natural Sciences, 2003 Carrier phase ambiguity resolution is the key to high precision Global Navigation Satellite System (GNSS) positioning and navigation. It applies to a great variety of current and future models of GPS, modernized GPS and Galileo. A proper handling of carrier phase ambiguity resolution requires a proper understanding of the underlying theory of integer ...

Fast Phase-Only Positioning with Triple-Frequency GPS
Sensors, 2018 In this contribution, we study the phase-only ambiguity resolution and positioning performance of GPS for short baselines. It is well known that instantaneous (single-epoch) ambiguity resolution is possible when both phase and code (pseudorange) data are
