Overview
T3900A of TRANSCOM is equipped with two independent channels of signal output. The two channels can be respectively used to simulate the real-time Beidou/GPS/GLONASS system signals and generate simulation and digital modulation signals. Therefore, a solution with integration of real-time simulation of navigation signals and generation of suppressing interference signals and professional deception interference signals is provided for navigation product manufacturers, which can reduce the costs of research, development and production and improve the efficiency of testing and verification.
T3900A has the functions of constellation simulation, trajectory simulation, environment simulation, anomaly simulation and interactive simulation control, and can be used to simulate the satellite signal environment received by the receiver, based on the test scenes. The following items are defined in the test scenes: receiver location at the given time of simulation, motion state, satellite/ constellation parameters and parameters of ionosphere and troposphere, multi-path, shade, interference and other kinds of environmental impact.
T3900A has the functions of constellation simulation, trajectory simulation, environment simulation, anomaly simulation, interference modulation and interactive simulation control. It can not only be used to simulate the Beidou satellite signal environment received by the receiver, based on the test scenes, but also can simulate challenging true scenes, including weak signal conditions, strong interference conditions and highly dynamic and multi-path interference, so as to test the receiver performance in the extreme environment. The simulator can also be used to simulate the anomaly of the satellite navigation system to test the receiver performance in the wrong environment and provide powerful support for research, development and production of receivers.
T3900A has a wide range of frequency coverage and power regulation and can be used to simulate various kinds of suppressing and deception interference, continuous wave signals, frequency sweep signals, analog/digital modulation signals, broadband noise and custom interference. The interference mode of suppression first and then deception can be perfectly fitted with actual field interference applications, and plays an important role in the interference test, unattended monitoring, major activity guarantee, electronic countermeasure, etc.
