Orbital dynamics free-flight dynamics only (defined in Table 5-9)
Total Channel Acquisition Time (assumes the
customer return service signal is present at the
SN ground terminal at the start time of the
return service support period)
Sum of the following:
1. PN (DG1 only) and carrier acquisition
time
2. Symbol/Decoder synchronization time
or Symbol/Deinterleaver/Decoder
synchronization time (if deinterleaving is
applicable)
