Detailed description

Hannaður fyrir atvinnu- og skemmtiferðaskipanir, Lars Thrane LT-1000 er eining fyrir staðsetningarupplýsingar (NRU) og hágæðar GPS áttaviti. Þessi þétti eining inniheldur 12 nákvæmar nemar, meðal annars segulmæla, hröðunarvaka, GNSS móttaka, loftþrýstingsmæli og hitamæli. Með notkun samruna nema og Kalman síun veitir LT-1000 rauntímaupplýsingar um sannar áttir, segulátt, frávik, misgengi, hroll, stefnubreytingu, staðsetningu, gervihnattaupplýsingar, botnhraða, botnstefnu, tíma og dagsetningu, loftþrýsting og hitastig, allt með háa nákvæmni og upplausn.

Nákvæmni og tengingarhæfni

LT-1000 er með 72-rasa GNSS móttöku, samhæfða GPS, GLONASS og BeiDou, með SBAS stuðning til að bæta nákvæmni staðsetningar með SBAS. Nákvæmni kyrrstöðu áttar er minni en 0,5° (rms) og hreyfistöðu minni en 1,5° (rms) við hroll/stefnubreytingu innan ±45° og snúningstíðni ≤ 45°/s. Tenging er tryggð með einni 8-stifta snúru sem styður NMEA 0183 (4800 eða 38400 baud) og NMEA 2000 samhliða, sem einfaldar innleiðslu í tilvistandi stýrikerfi. NMEA 2000 endahnútur er stillanlegur með DIP-rofa.

Uppsetning og endingarþol

Einingin er hönnuð fyrir einfaldlega uppsetningu á 1 tommu mastri eða þaksuppsetningu, með eina snúru fyrir aflgjöf (9-40 VDC) og gögn, og aflneyslu minni en 1W. Hönnunin uppfyllir kröfur sjávarumhverfis, með IP46 vatnsheldni og starfræna hitastigsviðkvæmni frá -40°C til +55°C. Hún er vottuð samkvæmt stöðlum CE, IEC 60945, IEC 60950, EN 300440-2, FCC, IC, RCM, RoHS, NMEA 0183 og NMEA 2000. Sérhver eining er stillt í verksmiðju. Tvær stillingar eru fáanlegar fyrir frávikstillingu: staðlaður "8-tala" eða aðlögunarhæf stilling sem bætir frammistöðu með tímanum. Þrátt fyrir að þessi vara hafi náð lokastigi fer framhaldandi tæknilegur stuðningur fram.

« Analyse technique du compas GPS Lars Thrane LT-1000 et son intégration système »

Le Lars Thrane LT-1000 se positionne comme une solution de référence pour les navires nécessitant une unité de navigation précise et polyvalente. Sa force réside dans son architecture multi-capteurs (12 au total) combinée à la fusion de données et au filtrage de Kalman. Cette approche permet de fournir non seulement un cap fiable, mais aussi des informations cruciales sur le roulis, le tangage, la position GNSS multi-constellations (GPS, GLONASS, BeiDou) et des données environnementales comme la pression et la température. Cette richesse d'informations est essentielle pour les systèmes de pilotage automatique avancés, les superpositions radar précises et les applications AIS.

D'un point de vue installation, le LT-1000 est remarquable par sa simplicité grâce à son unique câble de communication et d'alimentation et ses options de montage sur mât ou sur toit. La calibration de déviation adaptative est un atout majeur, particulièrement pour les navires où la réalisation d'une figure en 8 est complexe ou impossible. Il est recommandé d'assurer une installation par un professionnel qualifié pour optimiser les performances et respecter la distance de sécurité de 0,3 m par rapport aux compas magnétiques. Sa faible consommation (Bien que le LT-1000 soit un produit en fin de vie commerciale, il continue de bénéficier d'un support, ce qui garantit sa viabilité à court et moyen terme. C'est un choix pertinent pour ceux qui recherchent une unité fiable et éprouvée offrant un large éventail de données de navigation dans un format compact et économe en énergie, sans nécessairement exiger les toutes dernières innovations logicielles ou intégrations de plateformes propriétaires des modèles de nouvelle génération.

The LT-1000 operates with an input voltage of 9 to 40 VDC.

What are the mounting options available for the LT-1000?

The LT-1000 is designed for easy installation and offers two mounting options:

1" mast mount.Roof mount.

Is a single cable used for power and data?

Yes, the LT-1000 uses a single 8-pin cable for power supply (9-40 VDC) and NMEA 0183 and NMEA 2000 data transmission, simplifying installation.

What is the safe distance from a magnetic compass for the LT-1000?

The safe distance from a standard or helm magnetic compass is 0.3 metre (1 foot). It is important to respect this distance to avoid any interference with a magnetic compass.

Are there any precautions to take during installation to avoid interference?

Yes, to ensure optimal performance, it is recommended to:

Mount the unit on a rigid structure with minimal exposure to vibrations and shocks. Install it in an area where the ambient temperature is between -40°C and +55°C. Position it as far as possible from magnetic disturbances (such as speakers) and power cables.

How is deviation calibration performed on the LT-1000?

The LT-1000 offers two options for deviation calibration:

Standard deviation calibration (using an '8' pattern). This is the default setting.
Adaptive calibration.
These procedures are required to ensure reliable heading output.
