Abstract The weighted total least-squares (WTLS) estimate is sensitive to outliers and will be strongly disturbed if there are outliers in the observations and coefficient matrix of the partial errors-in-variables (EIV) model. The L 1 norm minimization method is a robust technique to resist the...
Abstract Precise point positioning (PPP) can achieve high-accuracy point solution using un-differenced code and carrier phase observations. Many PPP models have a higher measurement noise and multipath effects, resulting in a long time to obtain sub-decimeter to centimeter positioning accuracy...
Abstract In this paper, the magnetic model NGDC-720-V3 is used to investigate the distribution of crustal magnetic anomaly and the depth of Curie surface in west Himalayan syntaxis and its adjacent area. The Curie surface is compared with regional heat flow, the Moho, and seismicity. The results...
Abstract Extensive studies on signal noise analysis of Global Navigation Satellite Systems (GNSS) receivers are mainly based on zero and/or short baselines where a pair of receivers is required. This paper develops a new signal noise assessment method for a standalone GNSS receiver. In this new...
Abstract A new method is proposed to connect the orthometric height datum of island far from mainland with measurements of both ship-borne gravimetry and GNSS along the ship route connecting these datums. The methodology of route height datum connection is based on the astronomical leveling...
