General Options

Process Direction

The direction can be set to Forward, Reverse or Both directions. The forward and reverse solution should provide similar solutions for a static session but in some circumstances, a reverse solution passes when a forward fails, or solutions may differ because of different base satellite selections.

Static Solution Type

See Static Solution Types for information.

Frequency

Defines the type of data used for processing. The following settings are available:

Single frequency

Overrides automatic selection and applies single frequency (L1 only) processing.

Dual frequency

Overrides automatic selection and applies dual frequency processing. L1 / L2 data must be present in all observation files.

Automatic

Chooses between single and dual frequency processing depending on the common data available between the base and remote.

Constellation Usage

GrafNet supports GPS, GLONASS, BeiDou, Galileo and QZSS. By default, all common data will be processed, however individual constellations (other than GPS) can be disabled here.

Elevation Mask

Satellites below this mask angle will be ignored. The default value is 15°. Lowering this value allows more satellites to be used, possibly improving a solution with poor geometry.

Time Range

This option is only available when processing sessions individually.

Interval

Allows you to choose the processing interval. 30 seconds is the default processing interval as processing high rate data does not typically improve static processing results.
