4.5 Output Messages (NMEA Format)

4.5.1 $PASHR,POS Navigation Data

The $PASHR,POS sentence provides the position and velocity fix as well as the satellite
tracking status. The following specification describes only those fields supported by the Orion
GPS receiver implementation of the $PASHR,POS message.
If a 3-D navigation fix has been achieved the following sentences is sent out:
Quantity

single comma
Secondary identifier
single comma
Raw/differential position

S/W Config Code
Nominal number of characters (including sentence header and trailer) = 97 + 6 = 103. In
sounding rocket applications a typical message length of 105 characters is achieved.
Notes:
1) Raw/differential position 0 = Position is not differentially corrected
2) Data field is extended by one character for altitudes above 100km.
3) Data field is extended by one character for vertical velocities above 1000m/s.
