Chapter 1 INTRODUCTION

1.1 The RC2000 Antenna Controller Family

The RC2000 antenna controller family consists of the RC2000A, RC2000B POLAR, RC2000B AZ/EL,

RC2000C POLAR, RC2000C AZ/EL and RC2000C EL/AZ dual axis antenna controllers. All of the

various models are designed to work with 36-volt actuators and pulse type position sensors.

The RC2000A is a general-purpose dual axis antenna controller without the capability to track inclined

orbit satellites. The RC2000A does have the ability to be controlled via an RS-422 serial interface. An

IBM PC program, referred to as AUTOPILOT, is available to control the RC2000A and Standard Agile

Omni satellite receivers. An optional daughter board, designated RC2KPOL, allows the RC2000A to

control a rotating feed powered by a 24 volt DC motor that employs a potentiometer for position

feedback.

The RC2000B antenna controllers will track inclined orbit satellites, but do not have the ability to be

controlled via the onboard RS-422 serial interface. The RC2000B POLAR antenna controller is

designed to work with polar mount antennas. Two types of polar mounts are supported, elevation track

and declination track. With the elevation track polar mount, the elevation (or latitude) angle

adjustment is motorized. For the declination track polar mount, the mount declination angle adjustment

is motorized. The RC2000B AZ/EL antenna controller is designed to work with elevation over azimuth

type mounts. The RC2000B does not support the RC2KPOL daughter board.

The RC2000C controllers combine the serial communication and rotating feed support (provided by the

optional RC2KPOL daughter board) capabilities of the RC2000A with the inclined orbit satellite tracking

capabilities of the RC2000B. The RC2000C POLAR supports polar mounts with motorized elevation or

declination adjustments. The RC2000C AZ/EL is designed to interface with antennas that employ

elevation over azimuth type mounts. The RC2000C EL works with azimuth over elevation mounts.

Here is a brief listing of the capabilities of the RC2000 family of antenna controllers:

1. The controller utilizes a solid-state drive system capable of providing 8 amps to the antenna

actuators. The drive system has built-in over-current sensing, with mechanical relay backup to

disconnect the drive from the actuators in the event of a fault. It is possible with the RC2000 to

control antennas not powered by 36 volt DC actuators. See the white paper entitled “Controlling

Antennas Powered by AC or Large DC Motors with the RC1000 or RC2000 Antenna Controllers.”

This paper can be obtained from our web site at: www.researchconcepts.com.

2. The controller can control polarization via a polarotor type interface. In addition, an AUTO-POL

feature allows the polarization to be controlled via a digital input or contact closure supplied by a

receiver to the antenna controller.

The controller also has an internal expansion port that can accept optional daughter boards. Two

daughter boards are available which can provide polarization control, designated RC2KPOL and

RC2KHPP. The RC2KPOL is designed for use with the Seavey model ESR-124D motorized feed

with potentiometer feedback. The Seavey feed requires 24 volts at 500 milliamps. The RC2KHPP

option is designed for motorized feeds with potentiometer feedback which require 5 to 40 volts DC

at currents up to 3 amps. Version 1.x0 of the RC2000A software supports the RC2KPOL option.

Version 1.x1 of the RC2000A software supports the RC2KHPP option. The RC2KPOL and the

RC2KHPP options are supported in only the RC2000A and RC2000C series. Contact the factory

for versions of the RC2000C software that supports the RC2KHPP.

3. Position sensing feedback can be supplied by any pulse-based sensor, reed switch, Hall effect, or

electro-optical. There is no need for special sensors or actuators. The RC2000 antenna controllers

keep track of both rising and falling pulse edges from the pulse sensor for increased accuracy.

4. In each of the RC2000 controllers, the non-volatile memory can hold position and polarization data

for numerous satellites. The RC2000A can accommodate 50 geostationary satellites. The

RC2000B can accommodate 50 satellites total…5 of which may be in an inclined orbit. The

RC2000C can hold data for 35 satellites total…4 of which may be in an inclined orbit.
