Andrew Antenna StepTrack Antenna Controller APC300 (USED)

Brand: Andrew (ASC Signal)
Part number: APC300

Built-In Design Features. The Andrew APC300 controller incorporates a system self-test feature, a PC computer utilities
package and both local and remote fault reporting.

Multiple Control Functions. The Andrew steptrack control unit is capable of antenna positioning, performing steptrack, Smartrack® and program-tracking control functions via an internal microprocessor. enables both manual or automatic tracking of selected satellites by earth station antennas used in satellite communications.

Extremely Accurate Positioning. Antenna positioning resolution of 0.01° (± LSB) in both azimuth and elevation axes.

Ease of Operation. Convenient keypad data entry/recall, comprehensive 32 character alphanumeric display and easily accessible from panel mode selection.

Dual-Band Steptrack Operation. The APC300 antenna control system is operational in both the C- and Ku-Bands.

Continuous Status Display. The earth station controller provides a continuous display of the current system status.

Universal Power Supply. Auto-sense/select power supply enables worldwide operation.

Why Use a Steptrack System?

The apparent stability of a geosynchronous satellite is defined by its “stationkeeping window”. This “window” represents the
East-West (E-W) and North-South (N-S) travel limits that apply to a satellite. Most domestic geosynchronous satellites are maintained in a stationkeeping window of 0.1 degree.

As a satellite approaches the end of its fuel supply, the satellite owner may seek to extend its useful life by shutting off the North-South stationkeeping, permitting a controlled excursion in the satellite orbit to preserve stationkeeping fuel. An inclined orbit satellite will have its N-S movement or “eccentricity” increase from the predetermined value at the center of the stationkeeping window.

With the satellite in an inclined orbit, earth stations are required to have a more sophisticated tracking system to transmit or  receive a signal from the satellite. Earth station owners able to track these inclined orbit satellites may take advantage of significantly lower satellite transponder prices. As a satellite moves away from its “stationary” position, the earth station antenna must anticipate or detect the change and re-orient itself to receive the new maximum signal.
