LRIT Conformance
Long Range Identification and Tracking (DMR-800LRIT)

DMR-800LRIT comply with international Long Range Identification and Tracking (LRIT) regulations with the DMR terminal’s field-proven pedigree in ship security and vessel monitoring at low cost.

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.

LRIT regulations mandate that passenger ships, cargo ships of 300 gross tonnage or more and mobile offshore drilling units report identity, position and timestamp at both regular and configurable intervals, with compliance by December 31st, 2008.

While many field-installed Global Maritime Distress Safety System (GMDSS) terminals are capable of supporting LRIT, most will require retrofitting or a supplemental unit in order to comply with the LRIT regulation.

As a recognized Communications Service Provider (CSP), SkyWave provides reliable global coverage over the Inmarsat satellite constellation. The DMR-800LRIT terminal operates on SkyWave IsatM2M, a service based on enhancements to Inmarsat D+ and optimized for position and status reporting. It offers a compelling cost advantage in situations where existing GMDSS equipment requires upgrades or replacement.

Key features
  • Enhanced low elevation performance for operation at sea.
  • Seamless global coverage.
  • Extended operating temperature.
  • Discrete input feed.
  • Over-the-air programming.
  • Embedded Data Log.
  • Fully compliant with International Maritime Organization (IMO) requirements for Safety of Life At Sea (SOLAS) V/19-1 (Long Range Identification and Tracking).
  • Low cost alternative to retrofitting if your existing terminal is not LRIT compliant, save up to 50% on up-front costs.
  • Stand-alone operation, easy to install and does not require a crew interface, making compliance quick and painless.
  • Seamless transfer between Flags. SkyWave’s Versa automated provisioning system permits automated transfers between ASPs
  • Easy to install requiring only a power and ground connection with no complicated installation tools.
Plus all the features and benefits of the DMR-800L, including:
  • Enhanced low-elevation performance for operation at sea. The only IsatM2M terminal type-approved by Inmarsat to minus 20 degree elevation angle.
  • Global coverage using the IsatM2M network and automated ocean region switching.
  • Extended operating temperature range allows reliable deployment in some of the world’s most demanding environments.
  • Over-the-air programming enables remote reconfiguration of reporting frequency in full compliance with LRIT.
