Reliable connection thanks to acknowledged messages from and to your IoT assets.


Compact system size and affordable data plans enable a cost-effective global communication service.


Optimized hardware, communication protocol and network for low energy operation and longest battery life.



  • State-of-the-art nanosatellites, 5 kg class, Swiss made ​
  • LEO, sun-synchronous and equatorial orbits
  • Redundancy of critical satellite components​
  • Extra capacity in orbit, guaranteeing service reliability​
  • Propulsion and deorbiting capabilities to avoid debris in space
  • Controlled lifetime to keep the best performance in orbit​ and allow new features to be added to the network​


  • Proprietary low-power L-band chipset
  • Chip is integrated into the Astronode S module
  • Ease of integration (solder-down)​
  • Fully optimized for direct-to-satellite IoT applications
  • Can be used with different antennas, depending on the application​s
Meet the Astronode S


  • Optimized for LEO satellites network​
  • Bidirectional​ communication enabling acknowledgments, asset commands, deployment of security patches and software updates
  • Unicast/multicast capabilities​, one-to-one connection versus one-to-many​


  • L-band is the radio spectrum from 1 to 2 gigahertz (GHz)​, it is the most efficient spectrum for satellite M2M/IoT.
  • L-band radios have superior performance characteristics for IoT such as​ smaller antenna​, lower-cost RF components​, better propagation (no rain fade, lower power requirements)​, and fewer interference risks than other bands.
  • Astrocast is the only NewSpace LEO IoT network with access to L-band spectrum.
  • Long-term access to spectrum is guaranteed.


  • Bidirectional communication​
  • Low latency with full constellation (<15 min)
  • Over-the-air updates (OTAs)​
  • Multilevel AES 256-bit encryption
  • Azure compliant API (pull mode) for easy integration​
  • Customer Web Portal with data access​
  • Near real-time usage reporting ​
  • Pro-active support and monthly reporting
