Note that if GPS Fix Rate is set to “1=1Hz GPS” and the TrimTrac 1.5 is unable
to compute a fix when it enters the FIX State, but it was able to compute one or
more fixes since the last time it was in the FIX State, then the TrimTrac 1.5 will
generate a new REP_POSITION message using the most recently available fix
with the Position Age set to “1=Aged” thereby denoting that there had been
motion since the last position fix as shown for Message 02D7 in Table 13.
