RC3000 Antenna Controller Chapter 1 Introduction 5 1.3 Theory of Operation The RC3000 performs its functions via digital and anal og 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.
RC3000 Antenna Controller Chapter 1 Introduction 6 - performs communications between the microcontroller and the three (GPS, compass, remote control) serial channels - performs analog to digital conve.
RC3000 Antenna Controller Chapter 1 Introduction 7 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.
RC3000 Antenna Controller Chapter 1 Introduction 8 Programming Group Functions The programming group modes provide for initial confi guration of the controller and also provide screens to aid in maintenance and troubleshooting of the controller.
RC3000 Antenna Controller Chapter 1 Introduction 9 1.3.4 Antenna Pointing Solution The position (latitude and longitude) of the mount and t he longitude of a selected satellite are required to calculate a pointing vector from t he mount to the selected satellite.
RC3000 Antenna Controller Chapter 1 Introduction 10 The azimuth portion of the pointing vector is calculat ed with respect to local true North. The fluxgate compass is used to determine the heading of the center line of azimuth travel and the required movement in the azimuth axis is calculated.
RC3000 Antenna Controller Chapter 1 Introduction 11 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 RC 3000 powers up.
RC3000 Antenna Controller Chapter 1 Introduction 12 In the azimuth axis, movement in one direction is disabled when clockwise and counterclockwise limit switches are activated.
RC3000 Antenna Controller Chapter 1 Introduction 13 The Fast/Slow Transition parameter defines how far away from a target position the RC3000 will switch from fast to slow motor speed. The Coast R ange defines where the RC3000 will de-energize the motor drive to allow the mount’s inertia to coast into the target position.
RC3000 Antenna Controller Chapter 1 Introduction 14 1.3.8 Magnetic Variation In order to calculate satellite pointing solutions, the m ount’s orientation with respect to true North must be known. The RC3000 uses the fluxgate compass to measure the local horizontal component of the earth’s magnetic field.
RC3000 Antenna Controller Chapter 1 Introduction 15 1.3.9 System Performance The performance achieved by the RC3000 in locating and tracking satellites is dependent on the mechanical tolerances of the mount, the correctness of the installation and the accuracy of the various sensors.

RC3000 Antenna Controller Chapter 2 Installation 41 2.3 Initial Configuration Whereas Final Calibration (section 2.4) requires an open area with an unobstructed view of satellites, initial configuration may be done in any area ( possibly a shop environment) where the antenna may be moved throughout its entire range of travel.
RC3000 Antenna Controller Chapter 2 Installation 42 Azimuth/Elevation/Polarization Calibration . The next three steps calibrate the mount’s elevation, azimuth and polarization axes.
RC3000 Antenna Controller Chapter 2 Installation 43 2.3.2 Elevation Calibration Steps to perform elevation calibration will be descri bed starting with the elevation axis in the stowed position. STEP 1.- STOW Limit Confirmation With the elevation axis in the stowed position, go to the Limits Ma intenance screen (3.
RC3000 Antenna Controller Chapter 2 Installation 44 STEP 3a. – Inclinometer Reference Voltage To perform this step, raise the antenna until the reflecto r is in the reference position appropriate for this mount (see Appendix B). For the majority of mounts, the reference position corresponds to having the reflector’s face vertical.
RC3000 Antenna Controller Chapter 2 Installation 45 STEP 4. Elevation Scale Factor Calibration This step is performed to characterize the out put signal from the elevation inclinometer.
RC3000 Antenna Controller Chapter 2 Installation 46 NOTE: an alternate method for calculating the output signal from the inclinometer is to use the data supplied by the inclinometer manufacturer for each individual inclinometer and multiply by the gain (0.
RC3000 Antenna Controller Chapter 2 Installation 47 2.3.3 Azimuth Calibration Steps to perform azimuth calibration will be described st arting with the azimuth axis in the stowed position and the elevation axis above the DOWN limit. Movement in the azimuth axis is not allowed until the elevation DOWN limit switch is inactive.
RC3000 Antenna Controller Chapter 2 Installation 48 STEP 2. Initial Movement. The next step is to move the azimuth axis to conf irm drive and sensor polarit y. Azimuth clockwise and counterclockwise is defined as seen by an obser ver located above the antenna looking down on the antenna.
RC3000 Antenna Controller Chapter 2 Installation 49 Example: at +90 degree reference position the azim uth voltage is 3.86. At the –90 degree reference position the azimuth voltage is 1.14. The azimuth scale factor is calculated as: 180 degrees / (3.
RC3000 Antenna Controller Chapter 2 Installation 50 2.3.4 Polarization Calibration The following steps will require values to be entered in the POLARIZATION CA LIBRATION configuration screen (see 3.3.1.2.4). REF_V:2.50 OFF: 0.0 CONFIG-POL CCW: 90.0 CW: 90.
RC3000 Antenna Controller Chapter 2 Installation 51 The following diagram shows a typical situation of tw o waveguides that rotate together. Note that the diagram should be considered as if the observer is behind the reflector looking towards the arc of satellites.
RC3000 Antenna Controller Chapter 2 Installation 52 STEP 4. Clockw ise and Counterclockw ise Limits . Discrete Limit Sw itches . Some mounts may mechanize polariz ation clockwise and counterclockwise limits via actual limit switches.
RC3000 Antenna Controller Chapter 2 Installation 53 2.3.5 Fast/Slow Motor Speed The fast and slow output voltages for your particular mount will be set at the factory and typically will not need to be adjusted. On RC3000B models, there is only one fast/slow adjustment potentiometer on the analog board.
RC3000 Antenna Controller Chapter 2 Installation 54 2.4 Final Calibration The final calibration steps tune up the system for performing automatic location of satellites. 2.4.1 Compass Calibration Ferrous metal on the vehicle distorts the earth's magnetic field in the vicinity of the vehicle.
RC3000 Antenna Controller Chapter 2 Installation 55 2.4.2 Azimuth and El evation Alignment This step attempts to discover and compensate for offs ets in azimuth and elevati on position sensing. Offsets may be introduced due to mechani cal tolerances, slight inaccuracies in installation, etc.
RC3000 Antenna Controller Chapter 2 Installation 56 Elevation Alignment It is fairly easy to observe errors in the elevation calibration. If test data shows that the actual elevation angle that a satellite is f ound is consistently above or below the calculated target, then it can be concluded that an elevation offset should be applied.
RC3000 Antenna Controller Chapter 2 Installation 57 2.4.3 Signal Strength Adjustment The RC3000 can sense satellite signal strength via the L-band power detector (2.
RC3000 Antenna Controller Chapter 2 Installation 58 2.4.3.3 Signal Strength Channel Calibration This section describes the calibration procedure for a single channel. If two channels are to be used, the procedure will need to be run for each. The procedur e requires multiple steps and some steps are iterative.
RC3000 Antenna Controller Chapter 2 Installation 59 Adjusting the gain of the AGC channel in step 7 will m odify the offset voltage in step 6. Steps 6 and 7 should be run at least twice and possibly several times until the required adjustments are minimal.
RC3000 Antenna Controller Chapter 2 Installation 60 2.4.4 Pulse Scale Factors The pulse scale factors specify the number of pulse s counted per degrees (in radians) of movement for the azimuth and elevation axis. It is critical that these numbers are accurate since the tracking algorithms use them to determine step sizes (in pulse counts) .
RC3000 Antenna Controller Chapter 2 Installation 61 The azimuth scale factor is obtained by noting the difference in the azimuth pointing solution angles between two satellites and the pulse counts when on the sa tellites. For best results, use satellites that are as far apart as possible and make sure you have positively identified the satellites.
