Drivers Manual

Ulvertech Profiler (OSP Data) (Passive) - 31


Driver to decode depth, sound velocity and/or environmental observations, such as temperature and density, from an Ulvertech SD Profiler Data Telegram, Output (2): Profiler with Bathy Plus (O.S.P.) set to use OSP data or compensation enabled, or to decode sound velocity from an Ulvertech SC1 Profiler Data Telegram.
This driver can be used on the same COM port as an "Ulvertech Profiler" multibeam system driver.

Currently, the driver only works in passive mode, i.e. it will not decode the timetags from the data strings.
Therefore, determining a time latency might be important. Enter such a latency value in the database.

Note: In passive mode, the Ulvertech system must be set up for Continuous Output Profiler Data.

Decoding Notes

The driver does apply a scale factor of 0.01 to all of the decoded values, to convert depth readings in cm to meters, temperature readings in hundreths of a degree to degrees, water density readings in gm/100L to gm/L, and speed of sound readings in cm/sec to m/s.
Make sure to select the proper units in DbSetup, i.e. meters for depths and meters/second for sound velocity values. Scale factors can be left at 1.

  • SC1 Telegrams. The SC1 output only contains a speed of sound value, no depth or environmental readings. The driver automatically finds the field to decode the sound velocity, so no slot number is needed.
  • SD Telegrams. The slot numbers of the generic observations are used to determine which telegram field must be decoded for each observation.
    Enter slot number 8 for temperature, slot number 9 for water density. The driver automatically uses slot number 7 for ROV depth and slot number 10 for sound velocity.

Database Setup

To decode depth and/or sound velocity from the telegram, add a system of type "Underwater Sensor" and select driver "Ulvertech Profiler (OSP Data)".
Add observations of type "ROV Depth" and/or "Sound Velocity". No slot numbers need to be entered. Make sure to select meters (m/s) as observation units.

To decode the temperature and water density from the SD telegrams, add a system of type "Miscellaneous Systems" and select driver "Ulvertech Profiler (OSP Data)".
Add a generic observation for each parameter that is to be decoded. Enter slot number 8 to decode the temperature reading and slot number 9 to decode the water density reading.
These readings can be monitored in an "Observation Physics Display" and exported from a recorded database, using for example the "Analyze" module in the "Raw Database Manager".

Make sure to select the same COM port number and I/O parameters for this bathy system and (one of) the profiler system(s), if a profiler system (to decode the profiler data points) also has been defined.
