Built by university students and research organisations from 23 countries around the world, the QB50 constellation aims to study the lower thermosphere 200-380 km above the Earth.

There are 28 QB50 CubeSats on the ISS awaiting deployment and it is understood that 11 will be deployed in this first phase. The beacons should be activated about 30 minutes after deployment.

The QB50 CubeSats have downlinks between 435.8 and 438 MHz and reports from radio amateurs are most welcome. Beacon data received can be uploaded to a dedicated QB50 webpage at

Two of the ISS QB50 CubeSats, ON01FR 437.020 MHz and ON05FR 436.880 MHz, carry V/U FM transponders. The uplink frequency for both is 145.860 MHz with 210.7 Hz CTCSS, see http://site.amsat-f.org/2017/05/12/qb50-document-de-description-des-telemesures-des-satellites-on01fr-on05fr/
