Spectra Precision Survey Pro v5.1 User Manual

Some routines, such as point stakeout or offset points, cannot be run until
the calibration is properly solved.

Before starting data collection, tap

in the command bar. This directly

opens the

Meas. Mode tab (part of the Job Settings screen) where you can set

the acceptance criteria for different types of point collection:

– On the

Data tab, define the criteria for all the points you will collect

using

Point from the Data Collection screen or from the active survey map.

– On the

Topo tab, define the criteria for all the points you will collect

using

Topo SS from any measurement screen or from the active survey

map. Topo criteria are also used for feature collection.

– On the

Check tab, define the criteria for all the points you will collect

after tapping successively

Control (on the Data Collection screen), then

Check.

– On the

Control tab, define the criteria for all the points you will collect

after tapping successively

Control (on the Data Collection screen), then

Control.

– On the

Stakeout tab, define the criteria for all the points you will collect

through any stakeout routine.

Independently for each type, you can set the following criteria:

–

Solution quality: “Fixed only” or “Code, Float or Fixed”

– Max. tolerated

HRMS and VRMS values

– Max. tolerated

PDOP value

– Minimum number of satellites required (

Min SV).

– Minimum position averaging time, in seconds (

Average for)

– Automatically accept data collection or not when criteria are met.

NOTE: The last two criteria make sense when the receiver is set to static to give
the best averaged position. Since in

Topo SS point collection Survey Pro is

allowed to store a point using the single latest epoch of data, these two criteria
are irrelevant in that case (compare the two screen examples on the left).

If you enabled raw data logging for post processing, the

Post Process tab is

also accessible through which you will set the

RTK autonomous points field

as follows:

–

Allow in PPK Survey: Choose this option to allow Survey Pro to store an
autonomous solution for a data point. This will happen during an RTK
survey in case of intermittent or prolonged data link failure. By doing
this, you will be able, after the survey and through post-processing, to
calculate a precise solution for the point using the data from the GNSS
raw data file (PPK logging file).

–

Do Not Store: No autonomous point will be stored.
