RTK Data Collection
Once your horizontal and vertical projections are solved, you are
ready to collect data. The different measure mode settings and data
collection options are described below.

1. Go to Data Collection from the Survey menu. Tap
6HWWLQJV at the
top of the screen.
2. Select the receiver dynamics.
¾
Static on occupy will set the receiver to ‘static’ mode for
point occupations. When in static mode, the receiver
assumes no antenna movement and uses advanced
averaging techniques to compute the most precise position
possible.
¾
Dynamic always will leave the receiver in ‘dynamic’ mode
for point occupations.
3. Select how to Store GPS Raw Data .
¾
Lat, Lng, Ht will store an EP record in the .RAW file for
each point accepted.
¾
EP + Bl,CV will store an EP record, plus the raw base line
(dX,dY, dZ) and variance covariance information in the
.RAW file.
¾
EP + Bl,CV + Rx Raw will store an EP record, plus the raw
base line and variance covariance information in the
.RAW file, and send the station information to the
receiver’s internal file for post processing.
¾
EP + Rx Raw will store an EP record in the .RAW file and
send the station information to the receiver’s internal file
for post processing.
Note: Ashtech users store an Ashtech format .OBN record in a
separate file and do not store BL,CV records in the .RAW file.
