Iridium SBD transceiver 9603

  • Product description: Iridium Satellite SBD modem


One-fourth the volume and half the footprint of the Iridium 9602, the innovative Iridium 9603 transceiver 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.

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. It is also highly affordable, costing just slightly more than the previous-generation Iridium 9602.

Delivering two-way communications on a remarkable scale, the Iridium 9603 transceiver further expands the Iridium connected user base worldwide.
