CAS-2T a technical verification satellite for CAMSAT CAS-2 series amateur radio satellite launched at 23:42 UT November 9, 2016 on a CZ-11 rocket. The 2U CubeSat, developed by students from Fengtai District, Xicheng and Haidian District secondary schools, carries a ham radio 145/435 MHz FM transponder.

CAS-2T and another satellite with an amateur radio payload, KS-1Q (436.500 MHz), are attached to the final stage of the CZ-11 rocket. The final stage was originally expected to be in orbit for up to 30 days before re-entering the Earth’s atmosphere but reports indicate the orbit is 504 x 1030 km which could give an orbital lifetime of years.

The CAS-2T FM transponder does not appear to be fully functioning, see the report of Daniel Estévez EA4GPZ / M0HXM at http://destevez.net/2016/11/some-measurements-of-cas-2t-on-orbit-25/

KS-1Q like CAS-2T is also attached to the final stage of the CZ-11. It is reported to be a 1U CubeSat with a technology and launch vehicle monitoring payload.
