SVTB001
SVTB is a Software Defined Radio (SDR) simulator for testing of satellite telecommand signals against interferences and higher level attacks. It simulates both the uplink stations and the attacker’s position. It allows the setting of fully flexible scenarios by means of an interface with AGI STK and via definition of telecommand signal and modulation. For security assessment, the software can simulate attacks both at signal (jamming) and data level (smart jamming).
SIGNAL DECEPTION
Generation of pseudorange ramps on deception signals with configurable attenuation, Doppler and carrier phase offsets. Simulation syncronized attack
TELECOMMAND SIGNAL SIMULATION
- Simulation of the most widely used satellite telecommand signals:
- Direct Sequence Spread Spectrum.
- PCM/PSK/PM.
- PCM/PSK/FM.
JAMMING
- Fully flexible generator of jamming threats.
- AM period and duty cycle.
- FM frequency central shift, variation amplitude and variation rate.
- Bandwidth of wide band shaping component
NMA - Navigation Message Authentication.
SIMULATION SCENARIO
- Interface with AGI STK for simulation scenario.
- Scenario generation accordingly to AGI STK data.
OPERATION MODE
- Fully software simulation including the integrated Telecommand software receiver.
- RF simulation mode interfacing SVTB using National Instrument external hardware generating both reference signal and interference, assessing the performance of a real Telecommand satellite receiver.
- RF simulation mode SVTB using National Instrument external hardware generating only the jamming signal, assessing the performance of the overall Telecommand system.
SATELLITE ANTENNA AND FRONTEND
- Detailed and fully flexible frontend model.
- Settable satellite antenna pattern.
- Detailed computation of the antenna gain given the positions transceivers.
