RockBLOCK APNT gives you a straightforward way to add Iridium® PNT to a new or existing system without having to design your own carrier board around the Iridium PNT ASIC.

For development, you can power it over USB-C and connect to a virtual COM port. For embedded integration, there’s serial plus exposed SPI, I²C, UART and GPIO.

Iridium PNT provides an independent source of positioning and precise timing using signals from the Iridium Low Earth Orbit satellite network. Those signals are around 1,000 times stronger than standard GPS/GNSS signals, which makes them useful in systems where GNSS may be unavailable, degraded, jammed or spoofed.

For UAVs, USVs and other autonomous or remotely operated platforms, that gives you another PNT source to work with alongside the rest of your navigation stack.

RockBLOCK APNT is receive-only and does not include a GPS/GNSS receiver.

RockBLOCK APNT is currently available for inquiry only. Production is expected from late September 2026. The product shown is pre-production and specifications are subject to change.
