GPS Single-Satellite Manufacturing Test Simulator

This simulator is ideally suited for verifying the operational integrity of installed GPS systems. The software architecture easily allows the user to configure all primary GPS parameters, and it is equally suited for manual or automated use. While in manual mode, an intuitive interface allows the user to set parameters and save them in a file that can subsequently be modified in a text editor as necessary.

Navigation data is formatted from a web-accessible Broadcasted Ephemeris file, while Coarse Acquisition (C/A) codes are generated internally. Frames are modulated in GPS-compliant Binary Phase-Shift Keying (BPSK).

With this toolkit, you can select your satellite vehicle and navigation data with power and Doppler controls.
