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.
11 QB50 CubeSats were deployed in the first phase and a further 17 will be deployed in the second phase. The beacons should be activated about 30 minutes after deployment.
The QB50 CubeSats have downlinks between 435.7 and 438 MHz and reports from radio amateurs are most welcome. Beacon data received can be uploaded to a dedicated QB50 webpage at

LilacSat-2 (ON02CN), which deploys at 0815 GMT on Tuesday, May 23, is carrying a FM to Codec2-BPSK Digital Voice transponder, an APRS digipeater and camera. Further information at

Two of the ISS QB50 CubeSats deployed in the first phase, 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/
