TerraVision System Features
[communications][mapping][database][reporting][alarms]
Generic tracking applications rely on surface positioning by GPS fitted to the vessel or vehicle. Though this is the primary VMS component of all TerraVision systems, we also provide other data devices such as radar instruments, tags, alarms and sensors that can be communicated back to the base Control Centre. In many of its projects, TerraVision has designed and integrated the electronic components as well as the software to provide total turnkey solutions.
TerraVision has an extensive set of communications interfaces for long distance data and close telemetry applications. These range from international Inmarsat data transfers including tracking of vessels, to HF, VHF and UHF radio networks, cellular networks and paging links to contact personnel in response to events.
TerraVision supports the following satellite tracking types:
- Thrane Inmarsat C (active/passive)
- Thrane Inmarsat D+
- Stratos Inmarsat C (active/passive)
- Hugles Inmarsat C
- Argos
- Boatracs
TerraVision can be configured for messaging also, taking advantage of data compression / decompression that is available in the SatLink Email software to reduce communications costs. The SatLink Email software already contains appropriate drivers to manage the satellite communications unit and is a useful container for the other requirements of the unit such as email, fish catch reporting, sensor monitoring and standard messaging.
TerraVision not only provides vehicle position information, it incorporates vessel information within a Geographic Information System (GIS) providing spatial and non-spatial querying capabilities. TerraVision uses MapInfo™ as the map display module of the System The mapping display can support numerous digital maps which can be scanned image or vector data. This allows large and small scale maps covering regional and local areas to be viewed at the same time.
Vessel positions are displayed with lines joining consecutive positions. The latest positions of vessels are labeled with the name or license number,whichever was provided in the report.
The TerraVision System uses Oracle™ as it's database. The function of the database is to record and check identification, location, speed, direction, time and GPS status of each vessel. If any vessel's operating behavior should not meet a defined criteria, an event is generated which will trigger any number of alarms.
There are many different criteria built into the database, and these can be customised or combined together for multiple condition alarms
If the system installed has Intranet or Internet access, then it will be able to provide an optional "Patrol Vessel" interrogation system whereby a vessel, base or mothership can request:
- The current position of all vessels.
- The current position of all vessels of a particular class or type.
- The current position of all vessels within a certain distance of the querying vessel.
- The position reports of specific vessels for a given time interval.
- An immediate poll of a vessel.
- Position reports are automatically sent back to the vessel operator.
Alarms are event based - positional information for a given vessel is tested against defined conditions. Alarms can be defined by using alarm criteria incorperated into the TerraVision System database. General examples of the types of alarms available include but are not limited to:
- Date - Includes target times and days at sea.
- Regions - Exclusive or inclusive
- Position - ETA, anchor watch, heading and course
- Speed - Fast/slow
- GPS status - On/off, errors.
There are many more alarm types and several alarms can be combined together for multiple conditions: Such as IF Vessel X is inside region A AND travelling less that Speed Z an alarm will be triggered. Once triggered, an alarm is presented by the following methods:
- Window Alerts - Pop-up window on the chart display
- Sound Alerts - Beeps
- Email - User defined message sent with details of alarm.
- Pager/SMS - Brief text messages sent with details of alarm.
