Differential GPS with Survey
Pro
DGPS requires raw data measured from separate receivers to be
combined into a single range difference. For Real Time Kinematic
(RTK) data collection, the raw data can be broadcast using a radio
link or cell phones and the differential solution is solved in real time.
For Post Processing data collection, the raw data is collected in each
receiver’s internal memory and downloaded to a PC. Then, software
is used to combine the raw data and produce the differential solution.
Survey Pro supports three different modes of differential GPS data
collection: RTK, Post Processing, and Simultaneous RTK and Post
Processing data collection.
Selecting Data Collection Mode
1. Go to Settings from the Job menu.
2. On the Receiver card, select RTK or Post Process in the GPS
Mode drop down box.
3. Tap 2..
Note: This switch controls the display of the Survey menu when in
GPS mode. In RTK mode, the Survey menu contains items to
configure a base and rover receiver for RTK data collection. When in
RTK mode with post processing turned on, you will get simultaneous
post processing data collection every time you occupy a point. In Post
Process mode, the survey menu contains items to configure a static or
a stop and go receiver for post processing data collection.
