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.

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
.
