Official Service Provider to the United States Coast Guard

CLS America is the 24/7/365 customer service Help Desk for LRIT Compliance.


Call:  1(240)492-1943


Starting on January 1, 2009, under the International Convention for the Safety of Life at Sea (SOLAS), all passenger ships, high speed craft, mobile offshore drilling units and cargo ships of 300 gross tonnage and upwards regulated by the 160 Contracting Governments of the International Maritime Organization (IMO) must be tracked with a Long-Range Identification and Tracking system.


To comply with this regulation, these craft must be fitted with Long Range Identification and Tracking (LRIT) equipment programmed to transmit the identity of the ship and its location. The LRIT communication capabilities of the on board equipment will have to be certified by an ASP (Application Service Provider) recognized by the Administration, or by an authorized LRIT Testing ASP.


Contracting Governments must implement a national LRIT Data Centre or join a Regional/Cooperative LRIT Data Centre, to which ships will report their positions four times per day. In addition, these centres shall be capable of communicating amongst themselves and exchanging position reports upon request. Contracting governments will also be able to track any ship within a 1,000 nautical mile zone of its coastline, no matter what flag it is flying.


CLS offers a complete range of LRIT products and services, from implementing LRIT data centers to providing satellite data (Application Service Provider) and may also furnish LRIT compliant terminals. CLS has operated satellite systems for vessel tracking for over 20 years, thus offering you the best possible accompaniment in LRIT implementation.
