F.) Development Data On/Off ID:105 Switch Development Data Messages On/Off
Use this command to enable development debug information if you are having trouble in
attaining commands accepted. Invalid commands will generate debug information that should
enable the user to determine the source of the command rejection. Common input rejection
problems are associated to invalid checksum or parameter out of specified range. Note, this
setting is not preserved across a module reset.

G). Select Datum ID:106 Selection of datum to be used for coordinate transformations
GPS receivers perform initial position and velocity calculations using an earth-centered
earth-fixed (ECEF) coordinate system. Results may be converted to an earth model (geoid)
defined by the selected datum. The default datum is WGS 84 (World Geodetic System 1984)
which provides a worldwide common grid system that may be translated into local coordinate
systems or map Datum. (Local map Datum are a best fit to the local shape of the earth and not
valid worldwide.)
Examples:
Datum select TOKYO_MEAN
