5: Function Reference
F50 GPS Receiver LLA/XYZ Position
Use function F50 to display the current GPS position. Specifically, use function F50 to:
Select the positional coordinate system:
o
LLA (Latitude Longitude Altitude)
o
XYZ (Earth-Centered, Earth-Fixed (ECEF XYZ) coordinates based on
WGS 84). ECEF XYZ is a Cartesian coordinate system, and is some-
times known as a "conventional terrestrial" system. It represents posi-
tions as an X, Y, and Z coordinate. The point (0,0,0) denotes the mass
center of the earth, hence the name Earth-Centered. The z-axis is
defined as being parallel to the earth rotational axes, pointing towards
north. The x-axis intersects the sphere of the earth at the latitude,
longitude.
If LLA is selected, Altitude Mode shows the elevation in meters (WGS 84).
Warning: This GPS receiver is optimized for timing versus position accuracy.
Therefore, position information on this unit is not recommended for
navigation and other critical position applications.
Keypad
When Position Mode is LLA”, the position of the antenna is displayed in degrees, minutes,
and seconds using the following format:
<SIGN><DEG><°><MIN>'<SEC>"
where:
<SIGN>
= N or S for latitude; E or W for longitude; for negative altitude or + for positive altitude.
<DEG>
= two-digit degrees for latitude or three-digit degrees for longitude.
<MIN>
= two-digit minutes.
'
= ASCII character '
<SEC>
= two-digit seconds plus one-digit 10ths of seconds.
"
= ASCII character "
For example:
LATITUDE
N38°23’53.2
