The BeeSat-3 (Berlin Experimental and Educational Satellites) picosatellite, developed by students at the Technische Universität Berlin, is also part of the payload on BION-M1. The microsatellite, which weights one kilogram and is 10 by 10 by 10 centimetres in size is designed to spend a year in a circular orbit at an altitude of 575 kilometres, verifying the newly developed HiSPiCO S-Band Transmitter (Highly Integrated S-Band transmitter for PICO- and NANO-satellites) designed for microsatellites.
