SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
Description
GNSS Sensor Status
(2) There are no criteria on selecting a navigation solution when having 2 equal preference
valid navigation solutions. Any method of selection is acceptable.
(3) For each navigation solution, the ACD remains with its current label(s) until one of the
following occurs:
(a)
(b)
B.

RF Power Control

(1) The SDU is designed to interface and control multiple RF configurations. These vary in
the following ways:
(a)
(b)
(c)
(d)
(e)
(f)
(2) The RF configuration items are generally ORT specified, but in some cases, such as type
of antenna, they may also be communicated by the Antenna.
(3) The ACD manages the EIRP of each RF carrier to the level associated with the ORT
identified terminal class.
(4) Based on ORT settings the ACD determines Antenna Gain by the antenna gain reports.
(5) In a multichannel SDU, the RF power management algorithm:
(a)
(b)
(c)
(d)
(6) The ACD calculates the back-off to send to the HPA considering the following:
(a)
(b)
(c)
(d)
