SYMPTOM: GPS and Antenna Heights/Elevations and Total Station Prism
Heights/Elevations change after Re-Boot.
CAUSE: SurvCE and FAST Survey do not store to permanent storage (hard disk) changes in antenna height or prism height,
except in the following scenarios:
The hard save of antenna/prism heights is done when the user exits the program, when they save a configuration from the
instrument icon at the top of the screen, when they say OK to Configure Rover, Configure Base or Equip/Settings (for
TS), when they change jobs and when they enter
Equip/Comm Settings. Prior to release 1.50.007, due out in October, 2004, even Configure Rover did not save the height
information "to disk".
RESOLUTION:
If you re-boot, hard reset or otherwise exit the program by any method other than the normal File, Exit method, recent
changes to the prism height or antenna height may not be saved. On re-entering the program, the x,y position for GPS
work, for example, will very likely be
correct, but elevations may be in error. When using GPS, it is recommended, after a re-boot, that you do the command
Configure Rover to re-establish the correct elevations, and in all cases (GPS and Total Station) it is recommended that
you double-check your antenna or prism heights before proceeding.
