Creating a profile for GNSS receiver
| 
| 
Click Settings.
Click GNSS & Total stations.
Click Add to create a new profile.
Select GNSS Receiver (GNSS).
Profile page
The Profile page allows to enter the information on the profile type and instrument connected.
Profile name: name to assign to the profile
Mode: the receiver working mode, rover or base.
GNSS Rover: receiver operates as rover.
GNSS Base: receiver operates as base.
Brand: brand of the receiver.
Model: model of the receiver.
Device page
The Device page allows to define how the receiver is connected to the software and search the receiver using the bluetooth.
Device: name of the Bluetooth to connect.
To start a search in case the instrument is not in the list, click Add device.
RTK page
The RTK page allows to specify the type of device to use to send (base) and receive (rover) differential corrections.
None: no RTK connection. Receiver operates in autonomous mode.
Internal radio: use of internal radio of receiver
Internal GPRS (receiver): use of internal GPRS modem of receiver.
External radio: use of an external radio to receiver.
External GPRS (controller): use of the GPRS modem of the device (controller) or the Internet connection of the controller.
PPP (Precise Point Positioning): activates the PPP mode. It requires a Terrastar license and is available only for certain GNSS receivers.
RTK Radio page
In case the RTK has been selected as Internal radio, the software gives the possibility for certain models to configure the internal radio.
In order to accomplish radio regulations active in several countries, the access to some advanced settings (radio frequencies and spacing.) of the radio are protected with a password. Contact your distributor for more information.
The available field could change depending on the GNSS receiver model.
Click Tools to load the configuration saved in the GNSS receiver, or change the parameters in the page.
Channel: radio channel to use for transmitting and receiving. Base and rover must use the same channel and the same frequency. Click on the orange arrow to set the frequencies to use for the different channels.
Protocol: depending on the GNSS receiver model, the selectable options are:
Satel 3AS.
Satel 4-FSK/3AS.
Satel 8FSK.
Satel 16FSK.
Pacific Crest 4-FSK.
Pacific Crest FST.
Pacific Crest GMSK.
TRIMTALK GMSK 450S(P).
TRIMTALK GMSK 450S(T) .
Spacing: spacing parameter.
High Power: radio with high-power. Defines the power transmission.
FEC (Forward Error Correction): improves the reliability of data transfer over the radio by adding additional correction information to the radio messages.If enabled on the base, it must be enabled on the rover, too.
Format: format of corrections. base and rover must use the same data format.
Use Base ID:
For Rover: sets the receiver to receive the corrections only from the base identified by the specified Base ID.
For Base: Sets the name of the base. Base ID Identification of the base.
For GNSS receiver with multi-constellation it is recommended to work with RTCM3 MSM format.
RTK GPRS page
The available options depends on the GNSS receiver used.
In case the RTK has been selected as GPRS, the RTK GPRS page allows to define the NTRIP connection.
Provider: name of the phone provider providing GPRS service. Select a provider to define a new provider or to modify parameters of an existing provider. This field is available in case receiver is configured to work with internal GPRS (SIM card inside the GNSS receiver).
Server:
NTRIP: name of the permanent station service to connect. Define a service or to modify parameters of an existing service.
CSD (Direct call): name of the profile.
Mountpoint: name of mountpoint to use. Type in the name or select from a list. Only if an NTRIP server has been set.
Format Data: format of corrections. Set the same data format sent by permanent station (source).
Network type: type of network corrections to use. Only if an NTRIP server NTRIP has been set. This field is available only for certain models.
Add prefix to reference station: allows to define a prefix before the reference station name. This setting helps to identify the reference station in the points database.
RTCM3.1 messages: when activated, the software can process some of the messages provided by the RTCM3.1 protocol. In particular:
Messages referring to transformation parameters of the coordinate system.
Messages referring to corrections to apply for coordinates calculation
RTCM3.1 mode: RTCM3.1 messages can be used in following modes:
Horizontal & Vertical: correction and calculation of coordinates and of elevations.
Horizontal only: correction and calculation only of coordinates.
Vertical only: correction and calculation only of elevations
For GNSS receiver with multi-constellation it is recommended to work with RTCM3 MSM format.
RTCM3.1 can only be used with CORS network providing these messages.
Parameters page
The available options depends on the GNSS receiver used.
The Parameters page allows to edit the GNSS receiver satellite tracking settings.
Satellites Cut-off angle(°): minimum elevation above the horizon in degrees to consider satellites usable. To increase precision by avoiding satellites too low above the horizon.
Tracking GPS L2C: enables the tracking of GPS L2C signal, available for some GNSS receiver models.
Use GLONASS: enables the use of satellites in the GLONASS constellation.
Use GALILEO: enables the use of satellites in the GALILEO constellation.
Use BEIDOU: enables the use of satellites in the BeiDou constellation.
Use SBAS: available if None is selected as device on the RTK page. Enables the use of geostationary satellites of SBAS. The receiver can receive correction directly from SBAS satellites and improve the quality of the position without any type of RTK connection.
Position update freq.: frequency with which the value of the position is updated. For tracking operations, use a value of 5 times per second.
Hotspot: allows to use the GNSS receiver as internet hotspot, when a SIM card is available in the receiver. Available for some GNSS receiver models.
Antenna page
The Antenna page allows to edit the antenna settings.
Model: type of the antenna of the receiver.
Height: default receiver antenna elevation.
Additional offset: vertical additional offset to be applied.
