RCI RC1500 Tracking/Remote Controlled Antenna Controller For Single Axis Antennas

RCI RC1500 Tracking/Remote Controlled Antenna Controller For Single Axis Antennas

The Research Concepts, Inc. RC1500 is a single axis satellite antenna controller which is designed to interface to antennas powered by 36 volt DC actuators with built-in limit switches and pulse type position sensors.  The RC1500 was designed to provide years of reliable operation
through the use of a heavy duty solid-state drive network coupled with a novel microcontroller-based fault monitoring system. The 5 amp rated drive output capability is adequate for either moving feed trackers or full-size linear actuators and the Adapti-Drive digital servo speed control optimizes antenna movement for today’s demanding Ku-band applications. Additional features like an RS-422 communications port for PC control and a very userfriendly, menu scheme make the RC1500 a unique and highly adaptable piece of equipment. Overall, the RC1500 is well
equipped to handle the demanding requirements for cost sensitive domestic and international inclined-orbit satellite tracking.

RC1500 Tracking Algorithms

The RC1500 provides tracking for inclined orbit satellites via Step Track, Search, and Memory Track algorithms. An analog voltage (in the range of 0 to 10 volts) proportional to signal strength is required for peaking the satellite. This voltage is usually provided by a receiver or modem AGC output but can also be generated by a beacon receiver.

Setup of the tracking system is straight forward. From the controller’s CONFIG mode the user enters the following information …

Antenna Size,

Antenna Latitude and Longitude,

Maximum Tracking Error in tenths of dB,

Elevation Constant (the number of elevation position counts per degree of antenna elevation movement),

AGC Polarity (positive polarity implies that a stronger satellite signal produces a greater AGC voltage),

AGC Threshold (an AGC level above the threshold implies that a satellite signal is present).

When a track is initiated on a satellite the user is prompted for: the satellite�s longitude, the satellite�s current inclination, and the satellite�s frequency band(s) – C, Ku, C/Ku, L, X, Ka.

From this information the controller is able to automatically determine the optimum tracking parameters …

Step Track step size.

Interval between Step Track peaking operations.

Frequency of Memory Track antenna alignment operations.
