Abstract:
A low power GNSS receiver capable of real time kinematic position corrections is integrated with a low cost Iridium satellite communications transceiver to produce precise position measurements and report the results both as absolute displacement and as an alarm exceeding a threshold of motion. Messages for state of health are monitored for alarm and display. Statistical methods used to improve the measurement results will be shown. Satellite ephemeris algorithms are used to optimize power and precision. We anticipate applications that would benefit from long term autonomous displacement measurements.
