Description
-90 to 90
This field is set to the two’s complement value of the latitude, in units of
180/(2^25) degrees, referenced to the WGS-84 reference ellipsoid,
counting positive angles north of the equator and negative angles south
of the equator.
<LONG>
Longitude
-180 to 180
This field is set to the two’s complement value of the longitude,
referenced to the WGS-84 reference ellipsoid, counting positive angles
east of the Greenwich meridian and negative angles west of the
Greenwich meridian.
<LOC_UNCRTNTY_ANG>
Angle of axis with respect to True North for position uncertainty
0 to 84.375
The mobile station shall set this field to the angle of the axis for position
uncertainty, in units of 5.625 degrees, where 0 degrees is true north and
the angle increase toward the east.
