Contributions of thermal expansion of monuments and nearby bedrock to observed GPS height changes
Long‐term continuous Global Positioning System (GPS) observations have become an important tool for studying the various geodynamic processes. To fully study the geodynamic processes at GPS stations,…
Effects of Sensor Errors on the Performance of Map Matching
Analysis of various factors that may affect the quality of map matching based on extensive tests in Hong Kong finds that a deep understand of the accuracy of sensor errors on mismatching is important.
Evaluation Procedure for Coordinate Transformation
A simple procedure is proposed to evaluate the performance of a transformation, based on several predefined quality indicators, such as precision, invertability, uniqueness, conformality, and extensibility, for the transformation between different reference frames.

A Simplified Map-Matching Algorithm for In-Vehicle Navigation Unit
A simplified map-matching algorithm is proposed for an in-vehicle navigation unit, as the processing power of in-Vehicle processor is limited and results reveal this map- matching algorithm can improve the performance of the vehicle navigation unit significantly.
A New Indoor Positioning System Architecture Using GPS Signals
A new pseudolite-based indoor positioning system architecture that can receive real-world GPS signals, repeat each satellite signal and transmit those using indoor transmitting antennas and no hardware-level modification on the receiver is required.
Beidou satellite maneuver thrust force estimation for precise orbit determination
Beidou satellites, especially geostationary earth orbit (GEO) and inclined geosynchronous orbit (IGSO) satellites, need to be frequently maneuvered to keep them in position due to various…
