Current Research:

Steve is currently investigating and developing a reliable quality control system that can be adapted to an integrated navigation system for Spatial Information Collection. His research involves simulated and experimental studies of the GPS, GLONASS and Galileo satellite navigation systems, Inertial Navigation Systems (INS) and augmentation.

Research areas:

a. GPS/GLONASS/Galileo Receiver Autonomous Integrity Monitoring (RAIM).
b. GNSS/INS Integrity Monitoring.
