Iridium Certus Cobham Sailor 4300

Compact, Powerful, and Easy to Install

Compact and incredibly easy to install, Cobham’s SAILOR 4300 Iridium Connected terminal is a pinnacle of L-band satcom performance and reliability. It ensures that your link to the Iridium network is always available so you can operate safer, smarter, and more efficiently through the power of always available communication and digitally connected applications.

Iridium Certus is a new portfolio of global satellite services powered by Iridium NEXT, a ground-breaking second-generation L-band global satellite constellation established to deliver an uncompromising solution for the future of global maritime communications. The SAILOR 4300 is a Broadband Core Transceiver (BCX) type terminal with speeds offered over the Iridium NEXT satellite network that are suitable for data-heavy applications including; videoconferencing, multi-user Internet/VPN, IoT and telemedicine, alongside regular usage including email, electronic forms/reporting and crew communication.

Seemless Integration

While delivering high-speed, global connectivity as a standalone terminal, SAILOR 4300 has also been designed for seamless integration with onboard communication networks, making it an ideal solution for VSAT service providers to provide a cost-effective, high-speed secondary/back-up communications channel. SAILOR 4300 provides this capability using a specially designed, easy to configure VSAT integrator 'smart box'.

Next Generation

SAILOR 4300 utilizes the Iridium network to provide your on-board link through high bandwidth IP connectivity and three high-quality voice lines for global calling wherever you are.

Operational Continuity

SAILOR 4300 is designed to withstand the harshest maritime environments. Reliability is high and lifecycle costs are inherently low – it is built to such high quality that there is no scheduled service interval and no maintenance for at least 10 years after installation. But should something go wrong, you have the support and knowledge of Cobham SATCOM’s unique Global Service Network to get you back online wherever you are.

*ETF =
Early Termination Fee
*DSG = Dynamic Sharing Group's enable users to pool their monthly plans together, sharing allowances. This is subject to terms and conditions. A DSG requires application via Apollo Satellite and Iridium and therefore advance notice is required for set-up. DSG's require 5 SIMS minimum. If a DSG is set up prior to 5 SIMs being added to it, there is a 3 month grace period before you are charged for the 5 minimum SIMs. DSG are subject to a 12 month minimum duration period. Should SIMs leave the DSG within the initial 12 month period, the minimum of 5 SIMs will continue to be charged. DSG plans are limited to one migration per month.

Feature Name Cost
Message Delivery Point $350 Per Year
Mobile Termination (Annual Charge) $70.00 Per Year
Mobile Terminated SBD (MT-SBD) messages are sent to the Iridium Gateway via the Internet from a host computer system. The maximum length of a MO-SBD message is 1960 bytes. The maximum length of a MT-SBD message is 1890 bytes. Global network transmit latency for delivery of messages ranges from 5 seconds for messages of 70 bytes to approximately 20 seconds for maximum length messages. (Additional latency may occur across the Internet)
Mobile Termination Activation $280
Include Geo-Data FREE
Geo-Data is the last known location (latitude and longitude) of the device. When this option is enabled Geo-Data is included in the message content. By default it is enabled for all the delivery destinations. The SBD GEO data determined by the Iridium satellite network can be included with the message if you are not sending GPS data in the SBD message already. (accurate to about 15 miles)
Ring Alerts FREE
The Iridium Gateway will send a 'Ring Alert' to the Transceiver when a Mobile Terminated SBD (MT-SBD) message has been queued at the Iridium SBD Gateway. Your mobile application can then decide whether to retrieve the MT-SBD data message at that time or later.
MO ACK - Mobile Originated Acknowledgement FREE
MO ACK setting is used in conjunction with a Direct IP Delivery Destination. The default setting is off. When checked on, the Gateway expects to receive an acknowledgement from the receiving server that it has received the message. If the Gateway does not receive an acknowledgement, it will attempt to re-deliver the message for 12 hours. No other messages will be delivered to the receiving server until the first message is acknowledged.
