Iridium 9603N Transceiver

With the smallest form factor of any commercial satellite transceiver available today, the Iridium 9603 is ideal for space-constrained applications including monitoring, tracking and alarm systems.

One-fourth the volume and half the footprint of its predecessor, the Iridium 9602, the Iridium 9603 combines the global coverage of the Iridium satellite constellation with the low latency of the Iridium Short Burst Data service to provide highly reliable satellite communications from pole to pole.

Applications of the Iridium 9603N Transceiver

When you send or receive small packets of data (hundreds of bytes) in difficult geographic areas, Iridium SBD may solve your problem. It uses the Iridium satellite network, which has truly global coverage, and provides a vital means of communication for M2M applications.

It is ideal for remote weather stations, ocean drifters and buoys, monitoring of oil pipelines, controlling and reporting on equipment in the middle of nowhere. For basic telemetry and command/control applications where mobile signals don’t go, it’s ideal.

Iridium SBD is designed to move small packets of data, a few hundred bytes, from the middle of nowhere. If you’re looking to send photos, videos or large files, Iridium SBD is not for you!

We are SBD specialists. Whether you have existing Iridium equipment you’re looking to get airtime for, or you need help and advice on the best way to solve your particular problem, we’re here to help. Get in touch today – we’re friendly, knowledgeable, and we won’t baffle you with technology.
