Antenna And Control Systems
The latest antenna control system offers economical satellite tracking and control of earth station antenna. It is ideally suited for single AC fixed antennas and includes an Antenna Control Unit (ACU) and Outdoor Drive Unit (ODU).
• Precision Satellite Tracking and Control
• Ethernet Interface
• Full Software Upgradeability
The Antenna Control Unit (ACU) is the primary control and monitor interface point for the entire system, featuring a user-friendly interface.
• Three-axis antenna position display
• Three-axis antenna control facility
• (Ethernet; TCP/IP or RS-232/422).
• Step/Auto tracking features.
Beacon Tracking Recievers
Novella SatComs tracking receivers have been designed to track and measure pilots or beacons of all known commercial and military satellites. They are particularly suited to track satellite beacons (frequency and power stable signals generated on board satellites, used for telemetry and control) in earth stations using large antennae requiring good boresight alignment and stable uplink power.
Uplink Power Control
Novella manufactures the UPC3000 uplink power controllers, with an embedded beacon receiver module based in Novella’s established compact tracking receiver engine, to adjust transmitted power of an uplink station in accordance with beacon downlink loss at the same location.
These are very simple units with up to ten separate IF / gain amplifiers whose gains are adjusted by the DC output voltage provided by the beacon receiver as a measure of beacon level.
This is a very simple way of increasing the transmitted power to compensate for uplink fade which is assumed to be approximately the same as the downlink fade. Maximum depth of fade correction may be selected from 2 to 10dB, and it prevents saturation of the HPA.
