CPI Antenna Control System Model 123T-1

Overview

For over 50 years, CPI Satcom & Antenna Technologies Inc. (CPI SAT) experienced engineering staff has been developing high-precision, economical satellite tracking and control systems. The Model 123T-1 Antenna Control System provides precision satellite tracking for mobile, transportable and flyaway antennas. The Antenna Control Unit (ACU) is the operator interface point for the system, and features operator-friendly function menus. The Power Drive Unit (PDU) provides all motor and antenna connections.

Internal Tracking Receiver Option

The Model 250 receiver is available with L-Band or 70 MHz input. L-Band frequency range is 950-2150 MHz and the tracking C/No is 40 dB-Hz.

Tracking Accuracy - Optrack

Optrack provides high performance tracking of stable or inclined orbit satellites with an adaptive self-learning ephemeris modeling mode. The Control System accuracy (excluding non-repeatable mechanical errors) is normally better than 5% RMS (0.03 dB) of the receive beamwidth in winds of 30 mph gusting to 45 mph, satellite inclination of up to 15°, and signal scintillation of up to 2 dB.

Pointing Accuracy

Normally better than 0.07° RMS (0.05° optional) in winds of 30 mph gusting to 45 mph. This includes all drive train errors, but excludes structural errors between the transducers and RF beam.
