“Optima–B” GPS satellite navigation system terminal spoofing jammer

GPS spoofing signals transmitter “Optima-B” (hereinafter, the “Optima-B”) is designed to generate and emit, in real time, signals with characteristics and parameters identical to characteristics and parameters of the signals generated by GPS satellites at an assigned navigation receivers location.

The spoofing signals can be correctly recognized by the navigation receivers, which will result in false determination of the object cur-rent coordinates.

Technical specifications

Operation frequencies, MHz
L1 (1575.42) and L2 (1227.6)
The L1 is used to generate navigation signals with range finding C/А- code
per IS GPS-200E
The L2 is used to generate navigation signals with range finding C/A- code
per IS GPS-200E
Output power in each spoofing signal generating channel, minimum, mW
Coordinate system used
Time scale used
Number of satellites (spoofing channels in the signal)
up to 12
Output power tuning range, minimum, dB:

• for automatic tuning based on target range information
• for preset attenuator value
