Precise Surveying - Field Applications & Concepts
time= Observation time because only one point is surveyed.
Occupation time is irrelevant to Continuous Kinematic.
Raw Data Recording Rate: Interval, expressed in seconds, at
which the field equipment records the raw data received from
the GNSS constellation.
Implementation
Rules
1. Two systems are used: one (the base) is operated on a
chosen point while the other (the rover) is used in the
working area for the survey.
The base may be either a user-owned base, in which case
you need to properly locate your base (see Choosing a
Location for the Base on page 46), or a third-party
operated base.
With a third-party base, base data for your observation
times can be downloaded through the Internet (cf. CORS)
for post-processing. Rover data can also be uploaded to a
centralized processing system (cf. OPUS or AutoGIPSY),
which will in return provide centimeter-accurate position
results.
2. Data must be collected simultaneously by the base and
the rover. It is best to use the same raw data recording rate
on both units.
