IRIDIUM
iridium constellation has 66 satellites orbiting the Earth. Using the cross-link technology, satellites contact each other without the need of a LES. The Iridium network has a pole-to-pole coverage as a result of the enormous number of satellites in operation, the Low-Earth-Orbit trajectory allows for lower latency values for all kind of traffic and provide faster satellite communications.
A wide range of products are available that will benefit from the Iridium Satellite constellation, the most common being the Iridium Pilot terminals that can be used for both voice and data communications. The handset terminals also have a variety of accessories that allows the users experience global coverage in a more effective way.
Description
Iridium satellite communication systems are highly reliable maritime L-band solutions that operate as a roaming constellation in Low Earth Orbit (LEO)—unlike traditional geostationary (GEO) satellites centered around the equator—providing uninterrupted 100% global coverage (True Global) including the poles. Especially with Iridium Certus technology, thanks to their frequency structure unaffected by harsh weather conditions and low latency, they provide vessels with global-scale voice communication, emergency messaging, and reliable backup data connectivity.
Advantages
- 100% Global Coverage (True Global): Offers uninterrupted access in every geography, including polar regions, without any risk of going out of coverage anywhere in the world.
- Weather-Resistant Structure (No Rain Fade): Thanks to the L-band frequency spectrum, it does not compromise signal quality even under adverse meteorological conditions such as heavy rain, snow, or storms.
- Low Latency: Thanks to Low Earth Orbit (LEO) satellites, it offers much lower signal latency compared to traditional GEO systems, providing an advantage in real-time applications.
- Compact Hardware and Easy Installation: Thanks to small and lightweight antenna structures, it easily integrates into any vessel superstructure without requiring large radome areas.
Key Features
- L-Band Frequency Technology: A reliable spectrum structure that ensures satellite signals are minimally affected by superstructures, obstacles, or bad weather conditions.
- Multiple Simultaneous Line Support: The ability to run both high-quality voice (VoIP/phone) channels and IP data flow simultaneously through a single terminal.
- GMDSS and Safety Integration: A life-saving emergency and safety messaging infrastructure that fully complies with Global Maritime Distress and Safety System (GMDSS) requirements.
- Low Power Consumption: An energy-efficient hardware design that allows vessels to be continuously powered for long periods even using emergency battery systems.
