The PTD 2 (Pathfinder Technology Demonstrator) is a 6U CubeSat technology demonstration mission to demonstrate an improved attitude determination and control system that was developed under the Tipping Point Program.

Each PTD mission consists of a 6-unit (6U) CubeSat weighing approximately 12 kilograms and measuring 30 cm × 25 cm × 10 cm. Each PTD spacecraft will also be equipped with deployable solar arrays that provide an average of 44 watts of power while in orbit.

Development and demonstration of radiation tolerant, improved pointing accuracy attitude determination and control system will enable future deep space and long duration missions. The HyperXACT design will provide 5X improvement in reliability and pointing over the many state of the art systems whilst maintainig the 1/2 U form factor.

It was selected in 2018 by NASA's CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program.
