Astronode S
Product description
The Astronode S is a satellite communication module, connecting your IoT devices to Astrocast’s network. It enables the monitoring and control of devices with bidirectional satellite communication and up to 10 years lifetime off a single battery. The module features an SMT castellated pads form factor for trouble-free integration and soldering onto a PCB.
Low power
The Astronode S features a very low peak power consumption. This offers a more predictable battery lifetime as transmission power does not depend on the local network structure or regional RF band regulations.
Low cost
The use of L-band allows for smaller antennas, lower-cost RF components and better propagation than other bands. This reduces both size and cost of IoT applications.
Hazardous locations
The Astronode S is suitable for integration into devices intended to be ATEX/IECEx certified. The module works at low power, and without current pulses, it is also free of any built-in voltage step-up converters.
Bidirectional communication
The module, with its integrated proprietary chipset, handles worldwide direct-to- satellite communication over the L-band within the 1-2GHz spectrum. The encrypted communication enables acknowledgements, asset commands and the deployment of security patches. Both the satellite and ground station networks ensure maximum reliability thanks to a redundant setup.
