Tri-Band Satellite Simulator

Tri-Band Model No. TSS-CXK

A training test-bed and evaluation tool for satellite earth terminals

Designed for use as a training test-bed. The TSS-CXK Tri-band satellite simulator is used by operations personnel to set-up and operate flyaway tri-band satellite earth terminals in the field under realistic operating conditions without the need for an actual satellite. Use of the Narda simulator, in lieu of a satellite, permits signal acquisition by the earth terminal, antenna pointing, uplink power adjustment, signal reception, link closure and communications system adjustment to establish, acceptable bit error rates, with very low satellite terminal transmit power.

The Narda Satellite Networks satellite simulator is a broad band RF-to-RF converter that translates an input uplink frequency band to an output down link frequency band, simulating the satellite up and down link. Superior transmission characteristics and low phase noise accommodates digital data that would normally be transmitted via DSCS (X-Band) or Commercial (C-Band and Ku-Band) satellites.

The TSS-CXK Satellite Simulator contains built in wideband input and output horn antennas. The nominal TSS-CXK conversion gain, including antenna gains, is adjustable from -10 dB to -40 dB. Assuming a 2.4 meter earth terminal under test, with a range in the order of 300 feet between the terminal and the TSS-CXK, a received C/KT in the order of 75 dB-Hz can be achieved with a terminal carrier power in the order of only a few milliwatts (exact levels depend on the frequency of operation, and the specific terminal parameters). Operation is simple with the simulator located approximately 300 feet from the antenna horns pointed towards the terminal.
