RC3000 Antenna Controller Chapter 1 Introduction 1.0 INTRODUCTION The RC3000 antenna controller is designed for use with elevation over azimuth antennas on mobile satellite uplink vehicles. The RC3000 assists both the technically-oriented and the non-technical operator of a mobile satellite antenna system by automating the process of locating and locking on to a particular satellite. This process can be time-consuming due to several factors. For each shoot, the antenna may be located i

RC3000 Antenna Controller Chapter 1 Introduction 1.3 Theory of Operation The RC3000 performs its functions via digital and analog electronic equipment interfaced to the antenna’s motor drive and position feedback systems. This equipment is controlled through embedded software algorithms run by the RC3000’s microcontroller. This section provides an overview of the equipment, interfaces and major software functions. 1.3.1 Controller Description The following figure is a block diagram s

RC3000 Antenna Controller Chapter 1 Introduction 1.3.3 Operational Overview The RC3000 allows easy antenna operation via its menu based user interface. The screen displayed to the user is based on the current controller mode. Controller modes are divided into two major groups: operational and programming (see mode map in section 3.1.1). The operational modes provide for the normal operation of the antenna. The programming group provides for initial configuration of the controller an

RC3000 Antenna Controller Chapter 1 Introduction Programming Group Functions The programming group modes provide for initial configuration of the controller and also provide screens to aid in maintenance and troubleshooting of the controller. Configuration mode screens allow the user to customize and calibrate the operation of the RC3000 for use with a particular mount. Note that most configuration items will be factory set for correct operation with a particular mount. REF_VOLT:2.50 OF

RC3000 Antenna Controller Chapter 1 Introduction 1.3.4 Antenna Pointing Solution The position (latitude and longitude) of the mount and the longitude of a selected satellite are required to calculate a pointing vector from the mount to the selected satellite. Given the mount’s latitude and longitude and the pointing vector to the satellite, the RC3000 calculates the elevation (with respect to local horizontal) required. Feedback from the inclinometer on the elevation axis will b

RC3000 Antenna Controller Chapter 1 Introduction The azimuth portion of the pointing vector is calculated with respect to local true North. The fluxgate compass is used to determine the heading of the centerline of azimuth travel and the required movement in the azimuth axis is calculated. In the above example a true heading of 135 degrees to the satellite has been calculated. Based on the mount’s latitude, longitude and date, a local magnetic variation (see 1.3.8) of 10 degrees

RC3000 Antenna Controller Chapter 1 Introduction 1.3.5 Timekeeping There are several versions of time (system, sidereal, referenced and GPS) discussed within this manual. System time is maintained by the RC3000’s real time clock. The real-time clock is backed up by battery so that system time is available as soon as the RC3000 powers up. The system time is used to calculate sidereal time for maintaining track tables. Since satellite’s do not experience time shifts (such as from Stand

RC3000 Antenna Controller Chapter 1 Introduction In the azimuth axis, movement in one direction is disabled when clockwise and counterclockwise limit switches are activated. There is also typically a region in the center of azimuth travel indicating that the azimuth axis is in a position that will allow for moving the elevation axis down to the stow position. In the elevation axis, there are typically three limit switches. The UP switch prevents further movement up. The “DOWN” switch de
