Video: TinyGS, the Open Source Global Satellite Network with Jeffrey Roe EI7IRB


If you were to ask a member of the public about the subject of 'radio', they'll probably answer that it was some old technology that existed in the past and is now nearly dead. The reality is that it's hiding in plain sight. 

Think WiFi, Bluetooth, mobile phones, Satellite TV, Starlink, parking sensors, etc, we're surrounded by 'radio' technology. It's just that 'radio' has evolved and is increasingly in a digital format.

More and more devices now have microprocessors embedded and they are communicating with other devices using the concept of the 'internet of things'. One of the systems for doing this is LoRa (Long Range Low Power).

This concept has been developed so that radio signals from experimental satellites in low earth orbit can be received by hobbyists all around the world and then the data is fed back by the internet to the control station. One of the frequencies used for this is at 433 MHz in the radio amateur 70cms band.

TinyGS is one such network and is described as follows... "TinyGS is an open network of Ground Stations distributed around the world to receive and operate LoRa satellites, weather probes and other flying objects, using cheap and versatile modules."

Jeffrey, EI7IRB recently gave a presentation titled "TinyGS, the Open Source Global Satellite Network" to the Mid-Ulster Amateur Radio Club and they now have it up on their YouTube channel.

The video starts at about 7 mins, you can skip back to the start of you want to watch the introduction.
