  • Page 96 One means of using the ref sat process is to use DBS (Direct Broadcast) satellites. They have broad, high power carriers in the high band section of their transmitted signal. The spacing of these satellites (in CONUS) makes it very unlikely that an adjacent satellite will be acquired. DBS type satellites are often used as their high carrier power simplifies acquisition in poor weather conditions as well.

    AAQ Controller Functional Description 7.4.1 Pedestal Base Heading Every AvL antenna system ships with an Electronic Compass that is used to determine an initial heading for the antenna system’s base platform. This information, along with the antenna’s geographic location (latitude and longitude), is essential to determine a pointing solution (antenna pedestal azimuth, elevation, and polarization angles) for the target satellite.

  • Page 156: Sattant

    7.4.2 SATTANT SATTANT is the name AvL has assigned to a novel approach developed to refine the antenna base heading provided by the electronic compass using satellite received signal power, only. Unlike methods employed by other antenna controllers to refine the compass heading, SATTANT does not require a DVB receiver or an extensive, up-to-date satellite location database.

  • Page 157: Reference Satellite Function

    Figure 7.4.2 – SATTANT Process AvL’s SATTANT algorithm takes several factors into consideration when it selects the elevation angle for its satellite acquisition scan and the east / west intercept point. Every effort is made to insure that a reliable heading update is made at the end of this process. It should be emphasized here that the SATTANT process used to improve your heading accuracy is a mathematical process as opposed to the Reference satellite method which takes advantage of knowledge of location and or carrier information to provide more reliable data for acquisition.

    The second type of reference satellite uses a “DvB” carrier on a known satellite location and of a known frequency, bandwidth etc. While this offers a generally lower power carrier than the DBS type, the specifics of the carrier make it very unlikely that an adjacent satellite will be acquired. Use of a Reference Satellite requires the creation of a separate profile for each Reference chosen.

    Pedestal Coordinates - These are the AZ/EL spherical coordinates of the pointing vector, in the pedestal reference system. AZ is measured clockwise (when looking down on the antenna) from the AZ Home Position. The antenna boresight will be parallel to the frame of the antenna at the Home Position.
  • Page 160 Figure 7.4.6 - AAQ Acquisition Scan The required AZ width parameter is substantially influenced by the accuracy of the pedestal heading source used for acquisition purposes. The standard magnetic compass included with all AvL antenna systems is a moderately accurate device. However, like any magnetic compass, its reading is subject to significant errors when the antenna system is located close to large ferrous objects like metal framed buildings and large commercial vehicles or the electromagnetic fields generated by underground utility cables.

    When one of these signal sources is selected for acquisition, the AAQ will move directly to the “AZ Line Scan” starting point based on the pointing solution for the target satellite and initiate a raster scan. The AZ line scan is stopped immediately upon target satellite signal detection (modem/receiver lock indication) and the AAQ shifts directly into peaking mode.
  • Page 165 Figure 7.4.10 – Cross Scan Example As noted in the figure, the axes of the cross scan (two orthogonal line scans) align with the antenna’s Ped-AZ and Ped-EL axes. After the first line scan is completed, the AAQ commands the antenna to the scan angle corresponding to maximum received signal level.

  • Page 166: Fine Peaking

    7.4.11 Fine Peaking Optimal pointing of the antenna at the target satellite is usually achieved by a Ped-AZ and Ped-EL step scan technique. A series of small, equal changes in antenna pointing are made in one direction (Ped-AZ). After each small step, the received satellite signal is measured and compared to the level recorded at the end of the previous step.

  • Page 167: Linear Polarization Optimization

    7.4.12 Linear Polarization Optimization It is critical that the linearly polarized satellite ground antenna align its polarization vector closely with that of the satellite. Any mismatch between satellite and terminal antennas will reduce signal power on the forward and return links. Even a small misalignment of the polarization vector will significantly increase cross-polarized interference and further degrade the communications link between satellite and terminal.

    The popularity of satellite services using inclined geosynchronous satellites is growing and becoming a more frequent exception to the stationary rule. These satellites typically start their service lives in stationary orbits. As their station keeping fuel supply dwindles, the satellite operator decides to extend the life of the satellite by moving the satellite into an inclined orbit that requires much less fuel to maintain.

  • Page 169: Position Hold

    The AAQ’s TLE Track software module includes a TLE propagator program that takes a user provided TLE set and calculates the antenna Ped-AZ and Ped-EL angles versus time necessary to reliably acquire and accurately track the target satellite. The TLE set for a particular satellite will be updated from time to time based on NORAD tracking data and infrequent maneuvers performed by the satellite operator to maintain the satellite’s inclined orbit.

It is most prevalent at frequencies above 11 GHz.

    With no clear winner, the AAQ is designed to work with all three. Special provisions are made in the design of the AAQ software and available configuration parameter settings to compensate for their short-comings. Scan speeds can be varied to account for variation in response time and the rate at which new measurements are provided.
