Using SBAS
This is the easiest way of implementing real-time DGPS in
ProMark3.
As the correction data broadcast by SBAS uses the same
transmission channel as GPS, you don’t need any additional
equiment or cable. Receiving correction data will only require
one GPS reception channel in ProMark3. The allocation of
this reception channel will be managed internally so you won’t
have anything special to do except for the following:
• On the ProMark3 workspace screen, double-tap Utilities
and then DGPS Config.
•On the Mode tab, check SBAS by tapping on the button
next to SBAS.
• Tap OK. A message is displayed confirming that SBAS is
used as real-time DGPS source.
• Tap OK again. Close the Utilities folder and then run the
Surveying or Mobile Mapping application.
• Press the NAV key until the Position screen #1 is dis-
played. On this screen (see page 130), if you are not mov-
ing, you will notice that the “WAAS Average” indication is
displayed in the middle of the screen, meaning that the
ProMark3 now delivers DGPS position fixes.
