RC2000 Dual Axis Controllers
The RC2000 family consists of the RC2000A and the RC2000C Satellite Antenna Controllers. The RC2000C supports inclined orbit satellite tracking. The RC2000A and RC2000C are based on the same platform. An RC2000A can be converted into an RC2000C by upgrading the controllers software (stored in EPROM memory) and inserting/replacing a couple of ICs on the controllers digital board.
The following features are common to both the RC2000A and RC2000C ...
The RC2000C provides tracking for inclined orbit satellites via Step Track, Search, and Memory Track algorithms. Three versions of the RC2000C are available: the RC2000C AZ/EL for use with elevation over azimuth type antenna mounts, the RC2000C POLAR for use with polar mounts which employ either a motorized declination or latitude angle adjustment, and the RC2000C EL/AZ for use with azimuth over elevation type antenna mounts. 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 controllers CONFIG mode the user enters the following information ...
When a track is initiated on a satellite the user is prompted for: the satellites longitude, the satellites current inclination, and the satellites frequency band(s) - C, Ku, C/Ku, L, X, Ka.
From this information the controller is able to automatically determine the optimum tracking parameters ...
