SAT SIM - Satellite Simulator
SAT SIM – Satellite Channel Simulator
An advanced SDR based, Satellite channel simulator, providing multiple function for ground terminal testing. The SASSIM main functions are:
Satellite Channel Simulator
RF Recorder and RF player
Programmable Noise Generator
Digital IF front end
An advanced, Software Defined Radio (SDR) for real time simulation of a satellite channel, operating in the following frequency bands:
S-band (up to 2200 MHz)
Provides one or two channels, with 100MHz (500MHz upgrade) of bandwidth.
50MHZ per channel in dual channel mode
100MHz (500 MHz upgrade) per channel in single channel mode
The real time simulation of a satellite channel transfer function includes:
Provides long samples of an RF channel recording capabilities, with 100MHz bandwidth, for long durations up to a few minutes (and can be extended by ordering optional larger storage)
Provides digital noise generation, with 40dB control range, with single channel bandwidth of 5 MHz up to 100MHz(500 MHz upgrade).
The system basic interfaces are in the L-band and S-band
The system further provides one Ku/L+S or and L+S /Ku converter, enabling interfacing the system in the Ku band.
The SATSIM can be operated in Static or Dynamic modes:
Constant Delay generation, attenuation, noise and frequency offset.
The system is periodically configured with the parameters (normally once per second) and generates a continuous modification of the channel transfer functions, including increasing and decreasing of the propagation path, thus automatically modifying the attenuation, noise and doppler.
In this mode the system can accept instead of the channel transfer function parameters, a location of a satellite, earth station and target platform.
Test equipment for satellite modems, systems and terminals.
Recording and playout of signals for analysis or for validations test of systems.
Digital IF front end for system virtualization.
