Kinematic "on the fly"

The disadvantage of this method is

that an absolute minimum of 5

satellites on L1 and L2 is needed to

allow a fixing of ambiguities "on the

fly" in post-processing.

Discrete points can also be

measured within a "kinematic on the

fly" measurement chain.

Thus the operation procedure is very

similar to standard Kinematic and

Stop & Go surveying as described in

the previous chapter.

Configuration parameters for

kinematic on fly:

It is important that the logging

parameters are set correctly. The

parameter "Static Init" must be set to

"NO", while logging of static obser-

vations and moving observations

must be set to "YES".

Make sure that the recording rate at

the rover sensor is the same as on

the reference site.

Kinematic on the fly measurements

provide the trajectory of a moving

sensor without the necessity of a

static initialization. The sensor can be

moved from the first observation

epoch onwards.

Accurate results on the centimeter

level can only be obtained if dual-

frequency phase measurements are

available. Thus this method is

restricted to SR520 and SR530

sensors. Single-frequency receivers

like the SR510 sensor cannot be

used for precise kinematic on the fly

measurements.

The advantage of this measurement

method is that the sometimes time-

consuming static initialization is

avoided, thus the productivity in the

field will be higher.
