The receiver will not be able to acquire L-band signals reliably unless it has a GPS position and clock solution. When enough GPS satellites are acquired to start navigating, the Lband channel starts providing raw L-band packets and the L-band channel becomes stable and usable. At this point, the command "assignall gpsl1,idle can be issued. The L-Band will continue to operate. Even with the interruption of signal, the L-Band is able to re-acquire and track normally. The Omnistar Acquisition strategy assumes that we have a good GPS solution and that the local TCXO is steered to remove any frequency error.
