Over 25 years of flight heritage
FreeFlyer is flying today's most exciting mission
Leverage the power and flexibility of FreeFlyer Astrodynamics Software in your next mission. FreeFlyer provides complete astrodynamics functionality for missions of any size, any scale, any orbit regime, ITAR-free. With heritage on over 250 missions, customizable interfaces, and easy integration into modern ground systems architectures, FreeFlyer supports the full lifecycle of your mission. FreeFlyer has been independently verified and validated, and delivers flight-tested, proven accuracy. FreeFlyer is used for spacecraft analysis and operations by NASA, NOAA, USAF, USSF, NRO, and commercial and international space missions.
