CLS is the unique provider of LEO satellite terminal, manufactured in France, and it comes with a Type-Approval certificate issued by the Bureau Veritas. The LEO is made of a transceiver unit (including a GPS receiver and an Iridium satellite modem) and a junction box for connection to the mains. The terminal is specially designed to operate in harsh marine environments with its IP67 dome. It can be configured with SSAS buttons fully compliant with the SOLAS regulation. The LEO fully compatible with LRIT regulation requirement can be remotely configured.

The LEO satellite terminal tracks your fleet and vessel through Iridium’s satellite constellation that covers the whole globe from the North Pole to the South Pole. We predict that tracking will be further enhanced with the addition of Iridium’s new generation of NEXT satellites.

The LEO terminal has an internal battery that can last for up to 10 days when sending 1 position/hour. The terminal is also tamperproof with a tampering detector if transceiver is dismounted, tamperproof screws and tampering detector that generates a warning message when the dome is opened. As for the Ship Security Alert System (SSAS), CLS operation center provides 24/7 emergency calls to disseminate alerts according to the chain of command whenever the LEO terminal is being tampered with.

The LEO terminal can be configured to provide position data at 1 hour, 30mins, 15min and 5mins interval, depending on your needs. We recommend you to have a 1hour interval to reduce costs while being able to track your ship simultaneously.
