The TIsat-1 (TI is the abbreviation for the canton of Ticino ) is an amateur radio satellite that was developed and operated by students at the Swiss University of Applied Sciences SUPSI .

It is a Cubesat - small satellite with which the space suitability of various materials and components is checked: Both electrically conductive wires, which are made of various materials and have different diameters, and nylon threads are exposed to the atomic oxygen of the thin high atmosphere , who attacks these materials. A fault-tolerant, miniaturized on-board computer with three processors is also being tested.

TISat transmits on a frequency of 437.305 MHz (both radio beacon and telemetry ) in Morse telegraphy under the amateur radio call sign HB9DE.

The satellite was launched on July 12, 2010 from the Satish Dhawan Space Center on a PSLV rocket as a secondary payload to the Indian Earth observation satellite Cartosat-2B . The radio station HB9SRC of the amateur radio club of the SUPSI is the ground station of TIsat.
