GPS Initialization/Verification
Prerequisites
Ensure the following prerequisites have been met before proceeding:
S The primary CSM and HSO (if equipped) has been warmed up for at
least 15 minutes.
S The LMF computer is connected to the MMI port of the primary CSM
as shown in Figure 3-10.
S An MMI communication session has been started (Table 3-10), and
the
CSM> prompt is present in the HyperTerminal window
(Table 3-18).
Follow the steps outlined in Table 3-19 to initialize and verify proper
GPS receiver functioning.
