The LabMate is a low cost C/A P L₁ / L₂ system that generates a real-time static or dynamic user position derived from a composite 10 channel RF output.  The user can either enter any initial position and time, or read the real-time system clock to start the simulation which can then run indefinitely. The system is designed for the user who desires a continual position fix such as a factory certification or maintenance depot.  Importation of Yuma Almanac data and real-time collection and recording of receiver under test data is built-in. Built-in data recorders are provided for most receiver varieties such as Conexant, Garmin, Motorola, Trimble, Sirf, Rockwell, and others. The system can be upgraded to the LabPro via a software change.
