With the smallest form factor of any commercial satellite transceiver available today, Iridium 9603 is ideal for spaceconstrained uses, including fixed, mobile and battery powered applications. One-fourth the volume and half the footprint of its predecessor, Iridium 9603 combines the global coverage of the Iridium satellite constellation with the low latency of the Iridium Short Burst Data (SBD) service to provide highly reliable satellite communications from pole to pole.
