The Tracked Baseband Frequency should be a value between -5000 and +5000 for optimal
performance. This frequency value should be relatively stable when locked on to the StarFire™
signal. The StarFire™ Signal C/N0 value should be ~10 for optimal performance, a value of 4 is
considered good while less than 4 is marginal to bad reception.
QuickStart
This function allows the StarFire™ RTG navigation solution to be initialized to an accurately known
ITRF00 position and therefore eliminate lengthy pull-in times. This is typically a position previously
surveyed and converted to ITRF00 prior to initialization. NCT Binary message 0x42 allows an
external controller to initiate a QuickStart based on a known position, and to monitor the progress
and status of the QuickStart operation. Figure 52 shows the QuickStart Initialization window.
Figure 52: RTG QuickStart Initialization
The QuickStart process goes through the following modes:
INMARSAT Americas 41090
INMARSAT EAME 41080
INMARSAT ASPAC 41090
1. Idle: Following power-on and prior to any QuickStart having been requested, the QuickStart
mode is reported as ‘Idle’. Once a QuickStart has been initiated, the ‘Idle’ mode will not be
reported again until one of the following occurs.
a. Power is cycled on the unit.
b. A QuickStart ‘Idle’ has been requested. If a QuickStart has been initiated and is still in
progress, this will cancel it but not reset RTG navigation. This may result in only
partial completion of the operation. If the reported QuickStart mode indicates
