The ISTSat-1 is a Portuguese nanosatellite developed by students and researchers of the Instituto Superior Técnico (University of Lisbon), that was launched into orbit on 9 July 2024, aboard the Ariane 6 maiden flight. The project is part of the European Space Agency's "Fly Your Satellite!" programme. It is the third Portuguese satellite in space, after the PoSAT-1 and the AEROS MH-1, and the first to have been entirely designed and built in Portugal.

The ISTSat-1 is a CubeSat developed to optimise and complement aircraft surveillance systems by demonstrating the Automatic Dependent Surveillance-Broadcast (ADS-B) aircraft detection technology in orbit. Its mission lifetime is expected to be 12 months.
