For the very latest specifications visit www.aeroflex.com An innovative approach for verifying the operational integrity of installed Global Positioning Satellite (GPS) systems Avionics GPS-101 GPS Satellite Simulator • Verify operational integrity of GPS receivers quickly • Selectable Satellite Vehicle (SV) and Navigation (NAV) Data • Adjustable RF levels from -85 dBm to -145 dBm in 1 dB steps • Doppler control allows the operator to select a positive or negative carrier frequency shift of approximately 4 kHz • Stored GPS Almanac with real time clock • Direct connect to receiver or via antenna coupler • Battery operated portability Aeroflex is a leader in the design, manufacture and marketing of Avionics test systems. The IFR GPS-101 Global Positioning Simulator provides accurate and repeatable testing of Global Positioning Satellite (GPS) receivers. The GPS-101 achieves this testing capability by simulating a Global Positioning Satellite and generating a specific Satellite Vehicle (SV) and Navigation (NAV) data pattern. Coupled with remotely loaded GPS almanac information and RF levels/frequency control, the GPS-101 provides a portable test solution for verifying the operational integrity of GPS systems. The GPS-101 verifies the operational integrity of: • An integrated GPS receiver - antenna system (e.g. a hand held unit) with built-in test modes accessible by transmitting special satellite (SV) numbers and navigational (NAV) data word that will cause an indication or received signal strength. • An installed GPS receiver with remote antenna system. • Any GPS receiver or installation capable of indicating that a single satellite with appropriate navigation data was detected. Operation The GPS-101 provides dedicated front panel keys for all primary functions. Selected parameters are displayed on a wide viewing angle, high contrast, backlit LCD display. MODE KEYS RF LVL The RF level can be adjusted from -85 to -145 dBm in 1 dB steps via slew wheel control to verify GPS. DPLR The doppler control allows the operator to select a positive or negative carrier frequency shift of approximately 4 kHz to verify receiver acquisition and lock performance. SV Selects the satellite vehicle to be simulated (1 through 37). The almanac data is utilized to display an asterisk alongside the selected satellite vehicle if the satellite is unhealthy or not available. RF CONT The RF control selects the modulating source for the 1575.42 MHz
