Report Packet 8F-17 - UTM Single Precision Output
This packet reports position in UTM (Universal Transverse Mercator) format. The
UTM coordinate system is typically used for U.S. and international topographical
maps.
The UTM coordinate system lays out a world-wide grid consisting of the following:
• 60 North/South zones in 6° increments, extending eastward from the
International Data Line.
• 10 East/West zones in 8° increments, extending above and below the equator.
Coordinates within these boundaries cover all surface locations from 80° South to 84°
North and encircle the earth. Locations are indicated by offset from the equator and in
the zones east of the International Date Line. These offsets are known as Northing
and Easting, and are expressed in meters. UTM is not usable in polar regions.
