Iridium Certus 9770 beyond-line-of-sight connectivity product

Iridium Certus 9770 is a compact satellite communication module from Iridium for beyond-line-of-sight connectivity over the Iridium low-Earth-orbit network. It is a Certus 100 class module with a midband IP data link and two voice lines, intended for mobile and remote applications where cellular or radio coverage is not available.

For uncrewed aircraft and other mobile platforms, a satellite link of this kind provides command, telemetry and data transfer well beyond radio range, with global coverage and low latency from the low-orbit constellation. Iridium also names SCADA, remote asset management and IoT deployments among its uses, so the module suits vehicles and remote equipment that exchange moderate volumes of data.

The link figures define the data budget. The module supports IP data at up to 88 Kbps on receive and up to 22 Kbps on transmit, so uplink-heavy tasks such as video are outside its capacity while telemetry, status messages, commands and small payload data fit comfortably. It operates in the 1616 to 1626.5 MHz band and works with the Iridium Certus 100 service, which supports two voice lines in addition to data. The module uses an external passive omni-directional antenna, so no tracking mechanism is needed on the vehicle.

Mechanical and electrical details for installation: the module weighs 185 g and measures 140 x 60 x 16 mm. Input voltage is 12 VDC plus or minus 2.5 V, which gives a range of 9.5 to 14.5 V. Operating temperature is -40 to +70 degrees C, and the vibration standard is SAE J1455, which addresses the shock and vibration seen in mobile equipment.

Regulatory compliance is listed as CE, IC, FCC Part 25, ANATEL, Mexico, ICASA and ITU. Integrators should check which approvals apply to their operating region and to the complete terminal with its antenna.

Typical applications are long-range uncrewed aircraft command and telemetry backup, remote sensors and equipment, and mobile assets that need a global data and voice channel at low power and small size.
