System

SATCOM Technologies’ Model 950A Control System is comprised of an Antenna Control Unit (ACU), Tracking Receiver Unit (TRU) and a Power Drive Unit (PDU) which are linked via dedicated Ethernet connections. This configuration provides flexibility in locating the key system components, allows for variable separation distances, and providesimmunity to electrical ground plane transients.

The Model 950A isIntelsat- Standard A Compliant for great tracking performance, offers extensive modesfor pointing, acquisition and tracking and itssoftware is field-upgradable via a simple USB interface. In addition, the Model 950A is CE compliant for EU applications and features a touch-screen, large angle color display for modern user interfaces.

 

Tracking Accuracy – Optrack

Normally better than 5% of the receive beamwidth in winds of 30 mph gusting to 45 mph, satellite inclination of up to 15º and signalscintillation of up to 2 dB.

 

Monopulse Tracking
The monopulse option provides high performance and new life to existing antennas at an economical price point.

 

Pointing Accuracy

Normally better than 0.05º RMS in winds of 30 mph gusting to 45 mph. Thisincludes all drive train errors, but excludesstructural errors between the position transducers and RF beam.

  • Tracking, Pointing, and Acquisition modes
  • Ideal for single AC motor (per axis) antennas
  • Single, Dual, or Multi-speed antenna motor drives
  • Stable to highly inclined GEO targets
  • Flexible receiver options
  • Designed to minimize site cabling
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.

  • Optrack, which provides high performance tracking of stable or inclined orbit satellites with an adaptive,
  • Self-learning ephemeris modeling mode
  • Easy touch screen operation
  • Informative display with full text color readouts
  • Extensive diagnostic monitoring and test capabilities
  • Antenna and satellite simulators
  • Supervisory Control Link Ethernet; TCP/IP
  • Fully software field upgradable
Portable Maintenance Unit

The Portable Maintenance Unit (PMU) provides manually commanded, bi-directional control of all axes.

  • Hand held ruggedized unit with a 10-ft pendant cable and 40-ft extension cable for convenient local operation at the antenna
  • Backup means of moving antenna and is ACU independent
  • Four line, 20 character display for axis positions, tracking signal strength, and scrolling status messages
  • Modes include position jog and Hi/Lo speed
  • Optional weather proof access junction boxes at convienient antenna locations
  • Enable/Disable per axis

  • Rack mount Tracking Receiver
  • Extended low temperature operation
  • Extended Warranty
  • PDU configurable for various motor sizes and polarization controls.
  • E-Stops in panel mount or J-Box
Multi-Speed Inverter PDU

The Power Drive Unit (PDU) provides all digital control to the AC drive motors and contains the hardware/firmware logic to close the position and tracking loops with high resolution. 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 contains an internal fan for ambient air circulation and “hot spot” avoidance and an optional thermostat controlled, internal heater for cold weather operations. Single speed contactor configurations are also supported.

A lockable handle secures the access door while the system is operating. A Lockout, Tagout power disconnect is provided on the cabinet exterior. Mounted in the enclosure is a panel assembly consisting of the Antenna Control Board (ACB) logic, power supply, inverter drives, and various ancillary devices. Status interlocks and position signals report to the ACB and, while in constant communication with the ACU, the ACB transmits information and receives commands to control movement of any antenna axes.

Communication within the system via Ethernet between ACU, TRU, and PDU by a dedicated controller. A second Ethernet controller and port provides independent connection to M&C or customer WAN.

System design minimizes cable installation cost and complexity, and allows for flexible site layout.
