COBHAM SAILOR 100 GX User Manual

Calibration
99-145912-A Chapter 6: Configuration 6-15
Configuration
Tracking for satellite elevation above 75 degrees
It is not possible to use a system without heading input from the vessel's
gyro compass with satellites at an elevation of higher than 75 degrees
because the system will not have the required polarization accuracy of
the transmitted signal.
6.2.7 Fixed TX IF principle
The SAILOR 100 GX uses a TX IF gain concept. After calibration it
provides a fixed average gain from the TX-port of the ACU to the input
of the BUC. Advantages of the fixed TX IF gain principle are:
• Average TX IF gain independent of antenna cable length
1
• Compatibility with the GX TX Power control feature
When installing the SAILOR 100 GX you make a cable calibration. At that
point every installation adjusts to the same average TX IF gain regardless
of the ADU cable length. Additionally the SAILOR 100 GX system also
compensates the RX IF gain.
1. You find the maximum allowed cable loss at Prerequisites on page 3-18.
