DRAFT TrimTrac Locator Technical Manual      33 

These two messages are the most common and contain status information such as 
ReportType, WakeupType, Old/New Fix Indicator, Battery Condition, and 
Position Data.  The difference between the REPORT_POS and STATUS_MSG is 
that the REPORT_POS message contains position information. Whereas, the 
STATUS_MSG does not contain any position related information due to, for 
instance, the TrimTrac locator not being able to obtain a GPS fix.
