LRIT – Long Range Identification and Tracking

2. Sustav praćenja i identifikacije brodova velikog dometa – LRIT
LRIT (Long Range Identification and Tracking of ships – LRIT) sustavom omogućena je identifikacija i praćenje brodova na globalnoj razini u sigurnosne svrhe.Sustav uspostavljen Brodovi su dužni odašiljati podatke ovlaštenim tijelima – državama zastava. Uz zahtjeve rezolucije A.694(17), brodski uređaj za odašiljanje LRIT podataka mora ispunjavati i zahtjeve definirane u rezoluciji MSC.263(84):
automatski i samostalno odašiljati brodske podatke Podatkovnim centrima u vremenskim intervalima od 6 sati ili na zahtjev;
pružati mogućnost daljinskog odašiljanja podataka, bez obzira gdje se brod nalazi, kako bi se LRIT podaci mogli primati u promjenjivim intervalima, u rasponu od 15 minuta do 6 sati;
odašiljati podatke upravljanim (unaprijed zakazanim), odnosno pozivanim (na zahtjev) načinom rada;
mora biti izravno spojen sa brodskom GNSS opremom, ili mora imati svoj izvor određivanja pozicije.

3. LRIT
Prema SOLAS konvenciji od , svi putnički brodovi, HSC brodovi, mobilni odobalni objekti i teretni brodovi veći od 300 GT trebaju biti opremljeni LRIT sustavom koji je reguliran od strane IMO-a
Brodovi opremljeni LRIT sustavom imaju sposobnost odašiljanja identifikacijskih podataka i podataka o lokaciji broda
LRIT sustav mora biti certificiran od strane ASP-a (Application Service Provider) priznat od administrativne strane LRIT testing ASP
Vlade potpisnice LRIT projekta dužne su implementirati nacionalni LRIT podatkovni centar ili se pridružiti regionalnom LRIT podatkovnom centru za određeno područje s ciljem osiguranja razmjene podataka s brodova četiri puta dnevno
LRIT sustav također omogućuje obalnim državama potpisnicama ovog projekta da identificiraju svaki brod na 1000 M udaljenosti od obale, neovisno o državnoj pripadnosti broda

4. Sustav praćenja i identifikacije brodova velikog dometa - LRIT
LRIT sustav za jednosmjernu komunikaciju koristi postojeće satelitske sustave (Inmarsat i Iridium). U svakoj poruci, brodski LRIT uređaj odašilje identifikacijske podatke: (IMO broj i MMSI broj), geografsku poziciju broda te datum i vrijeme određivanja pozicije. Pozicija može biti određena pomoću integriranog GNSS prijamnika. Određena/odaslana pozicija temelji se na geografskim koordinatama u skladu sa WGS-84 geodetskim sustavom, a vremenska oznaka odaslane pozicije odnosi se na koordinirano svjetsko vrijeme (UTC). Jednom godišnje mora se izvršiti potpuno testiranje sustava, uključujući dostavu poruka administraciji, ovisno o državi zastave broda.

8. LRIT
Svaka država potpisnica dužna je osnovati nacionalni LRIT podatkovni centar ili se pridružiti regionalnom LRIT centru, isto tako država je dužna odrediti ASP (Application Service Provider) koji će upravljati komunikacijama između brodova
Podatkovni centar (Data Centre) prikuplja podatke brodova svih zastava i unosi ih u međunarodni LRIT sustav putem baze podataka za međunarodnu razmjenu (International Data Exchange) koristeći određene LRIT protokole
Nacionalni centri imaju mogućnost komunikacije sa ostalim centrima i razmjene potrebnih podataka, te imaju mogućnost identifikacije svih brodova do 1000 M udaljenosti od obale neovisno o zastavi broda

12. LRIT – conformance testing
In order to comply with the LRIT regulation, the LRIT communication capabilities of the onboard equipment will have to be certified by an ASP (Application Service Provider) recognized by the Administration, or an authorized LRIT Testing ASP. These Testing ASPs can issue Conformance Test Reports (CTR) for the terminals that pass the test.
Each terminal must be tested by an authorized Testing ASP to attest its LRIT conformance.
