LPWAN Sensor in Space

LPWAN Sensor in Space
The company, the university and the students behind this project were Sensum IoT, a small but fast moving start-up based in Tauranga, in collaboration with students from Toi-Ohomai Institute of Technology and students from Earth to Sky Calculus (the latter ran the project sponsored by Sensum and provided the real time tracking platform). Sensum supplied the SENSUM SenGeo, a Sigfox ready GPS tracker, which was attached with a camera to a weather balloon.

The weather balloon was launched from Kawhia, NZ on June 24th 2018. It reached 35km altitude with 24km recorded before GPS military restrictions jammed the signal (see red section in attached picture). It landed 230km away, in Galatea, 2h 20′ later.

The messages (GPS & altitude info) transmitted by the SenGeo device were received by up to 78 ground Sigfox basestations in New Zealand, from Whangarei (300km north of Kawhia) to one off Christchurch (800km south of Kawhia)! This is definitely a world record in terms of altitude for a Sigfox device, and possibly another record for the number of base stations picking up the messages.
