Survey Post Processing

.

Post processing data collection involves two steps. First, you must

open a file and begin logging GPS raw data for post processing.

Second, you must measure the antenna height and enter the antenna
and station ID for each point you occupy. The Post Processing

routine is described, starting on Page R-205

Projection

Survey Projection

.

The Projection Information screen is used to select and solve the

horizontal and vertical projections, which are used to transform GPS

measured WGS84 coordinates (latitude, longitude, height) into local
coordinates (North,East,Elevation). The screen is also used to switch

between mapping plane and localization mode. The buttons available

will vary depending on the current projection mode.

This screen and the screens accessed from it are nearly the same as

those found in the GPS module, which are described on Pages R-211

to R-233. The Solve Localization screens vary slightly and are
described on Page 257.
