Description
•
Reference set up as static over a point with accu-
rately known coordinates.
•
Rover moves from one point to another. The
receiver remains turned on while moving.
•
Static and moving raw observations are
collected.
•
Post-processing is compulsory.
For detail surveys and measuring many points in
quick succession.
High for baselines up to 30 km.
Very efficient for surveying many points that are
close together.
•
Reference set up as static over a point with accu-
rately known coordinates in WGS 1984.
•
Rover equipment is set up on a pole and moves
from one unknown point to another.
•
A data link, for example a radio or digital cellular
phone, transmits satellite data from the reference
to the rover.
