Evaluation of Low-cost GNSS Single Frequency Receiver Using Satrack Software

Satrack is an evaluation software, providing system integrators and end users with a quick and simple way to interface with ALLYSTAR GNSS chipsets, modules and boards. It supports easy Satellite communication, geographical information, logging data receiving, GNSS messages analysing, satellite tracking and graphical representation of signalling. Satrack is designed to communicate with ALLYSTAR’s Cynosure GNSS receiver via serial port or USB port. It provides general GNSS functions as well as real time and playback evaluation tools. The tested modes of operations are Static and Dynamic. The data required for evaluation were obtained from low-cost Global Navigation Satellite System (GNSS) receiver. The low-cost receivers used were Allystar TAU1302. Information including raw carrier phase measurements are provided by this receiver. Centimetre-level precision of positioning can be achieved by this receiver.
