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
Product Highlights
An advanced, Software Defined Radio (SDR) for real time simulation of a satellite channel, operating in the following frequency bands:
-
L-band
-
S-band (up to 2200 MHz)
-
Ku band
-
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:
-
Delay
-
Doppler
-
Noise
-
Attenuation
-
-
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:
Static Mode
-
Constant Delay generation, attenuation, noise and frequency offset.
Dynamic Mode
-
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.
Main Applications
-
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.
