RTK Engine Properties - General Settings

When you add the RTK Engine module, the RTK Engine Properties dialog appears with this tab.

If you select the module in the Tree view after you have added the module, the categories and settings of this tab appear in the Properties view.

Use the General Settings tab to view and edit the RTK Engine properties, such as the processing mode and parameters, and logging settings.

Processing Mode category

This category is only available while adding a new RTK Engine module to the system.

Processing mode: Define whether baselines are processed or absolute coordinates are output as result. The following table lists the selections available and gives more information.

Selection	Description	Characteristics
Baselines	Processes baselines and measures offsets to a reference position. The Baselines Settings category becomes available.	Fast. One station has to be kept fixed.
VRS	Processes a complete network and provides absolute coordinates as output. Needs and uses RTCM 3.1 and later correction data (including Multi-Signal Messages 4…7) received from an Ntrip Caster. The Correction Data Input category becomes available.	Absolute positions The connected mountpoint provides correction data produced by a Trimble Network Processor or RTXNet Processor module that covers a sufficient area. The RTK Engine sends for each station of its network an NMEA stream containing the current corrected position.

Baseline Settings category

Only available, if the processing mode is Baselines. Use the settings of this category to define the baseline parameters.

Use redundant baselines: If set to No, the RTK Engine connects each station once by a baseline to the nearest processed station. With the default selection Yes, the processor takes all possible information in the network into account and connects all stations positioned within the distance limits.

Maximum baseline length: The RTK Engine limits the processing of baselines to maximum distances of 35 km. To improve the time to fix and the position accuracy of results, you can further reduce this maximum baseline length.

Correction Data Input category

Only available, if the processing mode is VRS. Use the settings of this category to specify the connection to an NTRIP caster, providing the correction data. The settings of this category are the NTRIP client connection settings.

Satellite Settings category

Satellite Systems: The RTK Engine can make use of several satellite systems: GPS, GLONASS, BeiDou, and QZSS. By default, the RTK Engine module uses both, the GLONASS and GPS satellites (GPS and GLONASS option is selected). Other options are GPS only (GPS), GPS and QZSS, GPS, QZSS and GLONASS, and GPS, GLONASS, BeiDou, and QZSS.

Logging Settings category

Use logging filter: If set to No, the processing results are written into the database with the highest available data rate. If set to Yes, the additional Logging data rate property will be available, which lets you specify a data rate at which the processing results are stored in the database.

Logging data rate: Only available, if the Use logging filter property is set to Yes. Lets you select a rate at which the processing results are written into the database. If the input data is coming at a higher rate, the written values will be mean values. If it is coming in at a lower rate, the logging data rate is reduced to the incoming data rate. Available data rates are between 20 Hz and 10 minutes (Default: 15 seconds).

Rover position results: If set to Yes (default selection), the RTK Engine module stores its processing results into the database. If set to No, the module's Chart view is not available anymore, since no results are available for display.

Rover integrity support: If set to Yes, the RTK Engine module stores the processing results into the Trimble 4D Control Server RoverIntegrity database. The Rover Integrity module will be able to read the data and to use it for analysis. By default, set to No (no storage). If your system does not support rover integrity, the setting is not available for editing and set to No.
