Network - Seatools (MROV - SROV) - 31
Description
This driver decodes multiple message received from Seatools via a UDP interface.
The messages this driver decodes are:
ROV Position SROV
ROV Position MROV
Tether length and angles
Frame angles
Docking status and distances
Track offset
Umbilical information
All messages are received in ASCII and have an NMEA-like format.

Database Setup
The various messages are decoded as the following system types:
Message type | System type |
|---|---|
ROV Position MROV | Position Navigation |
ROV Position SROV | Position Navigation |
Tether length and angles | USBL |
Frame angles | Rotation Angle Sensor |
Docking status and distances | USBL |
Track offset | Miscellaneous |
Umbilical information | Miscellaneous & Underwater Sensor |
Depth | Underwater Sensor |
ROV Position MROV, SROV Setup
Create a database with a minimum of three object types to represent the vessel, MROV and SROV.
To decode the position select a Position navigation system on both the MROV and SROV.
On the first wizard page select as driver 'Network - Seatools (MROV - SROV)'.
Enter the port number on which data is transmitted.
The Receiver number is used as slot number to uniquely identify each Position navigation system.
Tether length and angles Setup
To decode the tether arms select a USBL system.
Verify that the correct driver is selected and that the port number is correct.
The values are received in meters, and recalculated to the survey unit of the database.
Make sure the unit on this wizard page is set to Meters.
The slot id's to use are TETH_PS (tether arm port side) TETH_SB (tether arm starboard side).
Frame angles Setup
To decode the angular data select a Rotation Angle sensor.
Verify driver and port number are correct.
All slot id's are predefined.
All values are received in degrees. Verify the unit is correct on this wizard page.
Docking status and distances
The docking status is decoded as a USBL sensor. Follow the steps described in 'Tether length and angles Setup'.
This observation is decoded as USBL Z.
The quality indicator is used to communicate the docking status (0 = undocked, 1 = docked).
Use as slot id DOCK.
Track offset & Umbilical information Setup
These observations are decoded as a Miscellaneous system type.
Verify driver and port number are correct.
All slot id's are predefined.
Depth Setup
Select an underwater sensor to decode the depth.
Verify driver and port number are correct.
The slot id's are predefined for both MROV & SROV. Select ROV Depth as observation type.
Values are received in meters and recalculated to the database survey units.
Verify the selected unit here is Meters.
Slot Id table
Below is a table that can be referred to to determine which slot id should be used to decode which observation.
Message | System | Observation | Slot id | Description |
|---|---|---|---|---|

Online
Verify all data is decoded correctly. Open an Observation Physics display and select the observations you are interested in.
If no data is received it could be due to an incorrect database setup or no data is received on the selected port.
The IO-tester can be used to check if any data is received on the selected UDP port .
If all is well, the output of the observation physics will be similar to the illustration below:
