Multi-Stage Satellite Phase and Code Bias Estimation
Precise point positioning with satellite navigation signals requires knowledge of satellite code and phase biases. In this paper, a new multi-stage method is proposed for estimating of these biases using measurements from a geodetic network. The method first subtracts all available a priori knowledge on orbits, satellite clocks and multipath from the measurements to reduce their dynamics. Secon...
متن کاملGPS and BeiDou Differential Code Bias Estimation Using Fengyun-3C Satellite Onboard GNSS Observations
Differential code biases (DCBs) are important parameters in GNSS (Global Navigation Satellite System) applications such as positioning as well as ionosphere remote sensing. In comparison to the conventional approach, which utilizes ground-based observations and parameterizes global ionosphere maps together with DCBs, a method is presented for GPS and BeiDou system (BDS) satellite DCB estimation...
متن کاملDifferential Code Bias Estimation using Multi-GNSS Observations and Global Ionopshere Maps
Measurements of Global Navigation Satellite System (GNSS) receivers are affected by systematic offsets related to group and phase delays of the signal generation and processing chain. The resulting code and phase biases depend on the transmission frequency and the employed signal modulation. Within this study differential code biases (DCBs) of legacy and modernized GNSS signals are derived from...
متن کاملIterative Code-Aided ML Phase Estimation and Phase Ambiguity Resolution
As many coded systems operate at very low signal-to-noise ratios, synchronization becomes a very difficult task. In many cases, conventional algorithms will either require long training sequences or result in large BER degradations. By exploiting code properties, these problems can be avoided. In this contribution we present several iterative maximum-likelihood (ML) algorithms for joint carrier...
متن کاملBias Transmission and Variance Reduction in Two-Stage Estimation
In this paper, we study the transmission of an asymptotic bias in two-stage regressions with non-iid errors and random regressors in which the possible endogeneity of some explanatory variables is treated via first-stage predictive equations. In particular, we characterise the transmission of an asymptotic bias in the first-stage estimates to the secondstage estimates. As an example, we fully d...
