CPI Antenna Control System model 990A

Condition:New OEM
Manufacturer:CPI, Inc.

CPI Antenna Control System model 990A

The CPI Antenna Control System model 990A can be used with almost any full motion antenna for precision satellite, spacecraft, or celestial tracking applications. The system comprises an Antenna Control Unit (ACU), Tracking Receiver Unit (TRU) and a Power Drive Unit (PDU) which are linked via dedicated Ethernet connections. This provides flexibility in locating the key system components, allows for variable separation distances and provides immunity to electrical ground plane transients.

Tracking Accuracy – Optrack

Optrack; Normally better than 5% of the receive beamwidth in winds of 30mph gusting to 45mph, satellite inclination of up to 15° and signal scintillation of up to 2dB.

Monopulse; For dynamic targets, normally better than 3% of the receive beamwidth for 30mph gust- ing winds. Minimum scintillation sensitivity.

Antenna Pointing Accuracy

Normally better than 0.010° RMS in winds of 30mph gusting to 45mph as measured at the axis position transducer. The ACU-bias correction Model will significantly supress systematic errors affecting RF beam spatial accuracy.
