The new Iridium 9603 is the latest transceiver available from Iridium. The 9603 offers the smallest form factor of any commercial satellite transceiver available today and is also one-forth the volume and half the footprint of the Iridium 9602.

The 9603 allows the user to take advantage of Iridium global network and also gives the capability of two way communications.

The Iridium 9603 is a revolution in scale, the compact transceiver is the worlds smallest commercially available two-way satellite data modem. It is designed especially for those who need to create smaller devices but still want to take advantage of having global coverage.
