Quad-Band (C, X, Ku, Ka-Band) Satellite Simulation System
Quad Band - X, C, Ku, Ka-Band, Phase Noise 10 dB (typical) better than IESS 308/309
Quad-Band Simulator
Digisat Quad-Band Satellite Simulator System- With the Wideband Global SATCOM (WGS) becoming operational, Digisat has expanded its Satellite Simulator product line beyond Tri-band, now including both Quad-band and Ka-band capabilities. Designed for use as a training test-bed, Digisat Satellite simulators can be used by operations personnel to setup and operate satellite earth terminals in the field under realistic operating conditions without the need for an actual satellite.
Signal Acquiring
Use of Digisat simulators in lieu of a satellite permits signal acquisition by the earth terminal, antenna pointing, uplink power adjustment, signal reception, link closure and communications systems adjustment to establish acceptable bit error rates with very low satellite terminal transmit power.
Key Features
- Simulates C-Band, Ku-Band, Ka-Band and X-Band satellites
- Permits earth station set-up without actual satellite available
- Ruggedized/ weatherproof enclosures for outdoor deployment
- Typical operation range is 50-1000 ft (actual range is determined by antenna size and power
- Low-phase noise for digital data
- Wireless remote control (availablewith Quad-Band Simulator)
- Lightweight
- Easy to operate
