AYECKA 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

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
