Analysis of Trimble Mini-T GPS Receiver

摘要

This report summarizes the function, capability, and I/O of the Trimble Mini-T GPS receiver (officially known as the Trimble Mini-T GPS Disciplined Clock Module; P/N 57303-05). The primary objective of this report is to document the intricacies of the Mini-T beyond the scope of its user manual, for the purpose of future integration of the Mini-T into larger, GPS- based systems. A detailed analysis on the input and output of the Mini-T was performed, down to the bit-level, and the basic Mini-T communication packets were dissected. Details and suggestions on how to write custom software or design hardware to communicate with the Mini-T are also provided, as well as a discussion on using an FPGA to communicate with the receiver.
