DRAFT TrimTrac Locator Technical Manual 33
REPORT_POS and STATUS_MSG
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.
