NAPA 1 or RTAF-SAT 1 (Royal Thai Air Force Satellite) is an earth observation nanosatellite built for the Royal Thai Air Force.

The Royal Thai Air Force contracted in July 2018 with ISIS of Netherlands for the delivery of an earth observation 6U CubeSat in orbit.

The main payload is a Gecko Imager, from the South African company SCS, capable of imaging in the RGB-band with an approximately 39 m ground sampling distance from the typical Low Earth Orbit. There is also a secondary payload, which is a demonstration model of the TriScape 100 Imager from developer Simera Sense, with a target ground sampling distance down to 5m from the typical Low Earth Orbit.

A second satellite, NAPA 2, is slightly modified. Besides the two imagers, it also carries an optical LED beacon. It was planned for late 2020 to fly on a Soyuz Fregat but has been moved to a launch via the ION-SCV 003 deployer on a Falcon-9 v1.2 (Block 5) in June 2021.
