Swarm vs. Iridium For Satellite IoT

Using Satellite for IoT If you are involved in building Internet of Things solutions for industry, you are probably familiar with radio technologies that connect IoT sensors to the Internet: WiFi, cellular, LoRa, etc. What about satellite connectivity? Wifi or...

Iridium Satellite Signal Monitoring

Project source code at GitHub: iridium-signal-strength-monitor In a previous article, I wrote all about Iridium satellite communication for IoT projects using an Iridium modem and simple Arduino technology. However, when trying to send a message to a satellite...

Automated Weather Satellite Ground Station

UPDATE: All NOAA APT satellites (NOAA-18, NOAA-19, NOAA-15) were decommissioned in 2025. NOAA-15 was decommissioned and stopped transmitting imagery at 15:28 UTC on August 19. You can see my very last received images on my site. Project source code at GitHub:...

Iridium Satellite Communication with Arduino

Note: Rock7 Communications is now Ground Control When deploying a microcontroller-based IoT solution or just doing experiments gathering data in the field, you often need a way to get the data back to your home base or to the cloud somehow. You’ve probably used...
