StratumFive offers a standalone, cost-effective solution for vessel operators to comply with SOLAS Chapter Vregulation 19-1 requirements. The DMR800LRIT is accepted by all major ASPs, National Data Centers and Flag States.




The DMR800LRIT is a pre-programmed, ready to use terminal that operates on the IsatM2M network. It offers a compelling cost advantage in situations where LRIT compliance is urgently required and an alternative for ship operators that do not want to burden the over used Sat C terminals with more requirements.


DMR800LRIT Hardware

DMR800LRIT HardwareThe DMR800LRIT hardware is a single hardware unit with built in GPS receiver and Inmarsat ISAT M2M satellite transceiver. The unit comes complete with power cable minimising installation time to no more than 20 minutes. Once connected to mains, the vessel is automatically activated and opens to conformance testing from your flag’s Authorised Testing ASP’s.


DMR800LRIT Installation and Conformance Test

DMR800LRIT InstallationThe system is deployed pre-programmed and auto activated and will start transmissions automatically when connected to the vessel’s power supply.

  DMR 800 LRIT operates on the IsatM2M communication system, which provides coverage between +/- 75 degrees latitude globally. MarineTrack IsatM2M operates on 5 Inmarsat satellites: AOR-W, A OR-E (15.5˚W) IOR (64˚E), POR (178˚E), PAC-C (142˚W). YES YES
  IT terminal is to transmit the ship’s LRIT information at 6-hour intervals. However, the LRIT Data User may specify a more frequent transmission interval (via the ASP). All such changes are notified by an immediate response with position report that also indicates the new reporting rate. YES YES
  When a ship is undergoing repairs, modifications or conversions in dry-dock or in port, etc, the administration may reduce the frequency of the transmission of LRIT information to once every 24-hour period, or may temporarily stop the transmission of such information. All such changes are notified by an immediate response with position report that also indicates the temporary reporting rate (i.e. 24-hour or off). YES YES

1. Do you have a worldwide service station network?
a. The ISATM2M is a completely self contained and sealed unit, you can not open to inspect, if the unit fails over air diagnostic are performed to confirm failure and unit if failed then replacement will be sent to next port of call, subject to timescales.

2. Hardware warranty?
a. One year.

3. Where is the best location?
a. The DMR800 LRIT is designed in the same way as Sat C and will need a clear view to sky away from any shadow areas of accommodation or funnel. It is advised to place in a similar place as existing GMDSS or SSAS locations.

4. Do we need a technician to attend to install unit?
a. The DMR800 LRIT is design with a single IP60 heat wrapped bonnet connection at the terminal end connect to standard 20m two core cable. It has been designed for ship crew to install with ease in limited time.

5. Where do we have to connect the power into?
a. It is advised to connect to emergency radio station power to ensure limited power interruption during service. The termination connect should have the ability of being turned on or off as per the LRIT requirements.

6. We are a tanker company and do not wish to perform hot work to fit the unit?
a. The DMR800 LRIT is manufactured with performed fitting bracket.

7. Do you have stock?
a. We have stock available at all times even for bulk orders.

8. What is the weight of the dispatched unit?

a. The unit is guaranteed to pass if sited correctly and will be exchanged if failed as per our warranty policy.

11. Does the unit come complete with a conformance test?
a. No, because tests can fail if the unit has not been correctly sited or installed. The conformance test has to be carried out by the flag state’s appointed ASP.

12. Who pays for the reports?
a. The flag state not the ship owner.

13. After the test what happens?
a. The unit will be transferred to your Flag State Data Centre Administrator and will commence reporting as per LRIT requirements.

14. Do we have to enter any details into the unit?
a. No, the unit comes preinstalled with all LRIT firmware, each unit comes with a unique ID number that must be kept and produced when performing the conformance test.
15. Does the DMR800LRIT come pre-activated?
a. Yes, as soon as power in enabled to the unit a preloaded activation message will be send to confirm initialization. Once received the owner must then contact the flag ASP to conduct a conformance test.
