6. Setup – Satellite Configuration
If your system will be using iDirect OpenAMIP, you will not need to configure any satellites and can skip this chapter.
The values that these parameters are set to depends on the hardware configuration required for each satellite. Configure each
of the satellites that airtime services will be provided on so that any one of them can be selected, remotely or by the user
onboard. The satellite selection will in turn control the hardware on the antenna pedestal to select the correct TX & RX
hardware and the correct tracking settings.
Sea Tel provides quad-band LNBs as standard on the Series 12 Ku-Band antennas.
1. Access the Satellite Configuration screen.
2. If no satellites have been configured, or
you need to add another, click Add
Satellite.
3. Enter a name for this satellite you are
creating.
4. Enter the Longitude position of this
satellite.
5. Select the satellite that your airtime
services will be provided on.
6. Determining the IF Tracking Frequency (MHz)
The IF Tracking frequency parameter is a value entered into the MXP MHZ Sub-Menu. The value itself
may be provided by your air-time provider and the MHz value will be entered directly in this sub-menu.
Or, the RF downlink frequency of a specific carrier on the desired satellite can be obtained from a satellite
website and calculated by using the formula RF- LO = IF. When you take the Satellite Transponder
Downlink RF value and subtract the LNB’s Local Oscillator (LO) Value, the resultant value will equal the
Intermediate Frequency (IF). It is this IF value that will be entered into the MXP for tracking purposes.
The MHz and KHz are entered as a single value.
Example: Assuming an LNB LO value of 11.25GHz: We want to track a satellite downlink carrier at
12268.250 MHz.
12268.250 MHz – 11250.000 MHz = 1018.250 MHz IF
7. Enter the entire six digits of the
“megahertz and kilohertz” is simply
entered as one value in the Frequency
field.
8. SAT SKEW
SKEW is used to optimize the polarization of the feed to the desired satellite signal. It is entered when a
known satellite is skewed. Use Polang to peak the polarity.
