GD Satcom Model 930A Antenna Control System

SATCOM Technologies’ Model 990 Control Systems 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. The Model 990 Control Systems can be used with almost any full motion antenna for precision satellite, spacecraft, or celestial tracking applications.

  • Tracking, Pointing, and Acquisition modes
  • Single drive per axis, multiple axes
  • AZ/EL, X-Y, HA/Dec, and AZ/EL/Tilt pedestals
  • GEO, LEO, TT&C, RADAR, or Celestial applications
  • Single or Multi-Band operation
  • Wide dynamic range and fine control resolution

For over 50 years General Dynamics SATCOM Technologies’ experienced engineering staff has been developing high-precision, economical satellite tracking and control systems.

As the world’s leading manufacturer of satellite and groundbased products and services, our systems are designed using cutting edge technology. Our control systems can be used with almost any antenna and support a wide range of applications. The systems feature an easy-to-use, modern Ethernet interface, and are software upgradeable to protect your investment. All control systems come with an end-to-end warranty and are supported 24/7/365 days a year by our technical customer support team.

System

Our latest Antenna Control System, the Model 930A, offers economical satellite tracking and control. It is ideally suited for single AC fixed antennas and includes an Antenna Control Unit (ACU), Internal Tracking Receiver (TRU) and a Power Drive Unit (PDU). The Model 930A is our replacement for our long-standing Model 7134 Antenna Controller and is backwards compatible with our reliable Model 7150 Power Drive Units.

Tracking Accuracy - Enhanced Memory Track

Normally better than 10% of the receive beamwidth in winds of 30 mph gusting to 45 mph, satellite inclination of up to 5º.

Pointing Accuracy

Normally better than 10º of the receive beamwidth, RMS in winds of 30 mph gusting to 45 mph. This includes all drive train errors, but excludes structural errors between the position transducers and RF beam.

Features

  • Tracking, Pointing, and Acquisition modes
  • Ideal for single AC motor (per axis) antennas
  • Stable to 5° inclined GEO targets

Antenna Control Unit

The Antenna Control Unit (ACU) is the primary control and monitor interface point for the entire system, featuring a friendly touch screen windowed interface.

Multi-Speed Inverter PDU

The Power Drive Unit (PDU) provides digital control to the AC drive motors. It also provides controlled acceleration and deceleration profile & speed regulation range of up to 15:1 with conventional inverter rated AC motor (antenna system dependant).

The inverter PDU’s are free-standing, housed in an NEMA 4 (IP66 equivalent) aluminum enclosure and contains the electrical/mechanical components necessary to move the antenna. The PDU has an optional thermostat controlled, internal heater for cold weather operations.

A lockable handle secures the access door while the system is operating.
