Space Applications
Global positioning satellites (GPS) navigation systems have the ability to sense space vehicle trajectory, attitude, time, and relative ranging between vehicles and can be efficiently built into a single package. Significant savings in space vehicle operations may be achieved through GPS autonomous spacecraft guidance systems. 

Earth Applications
Current custom manufacturing process and technology for microsatellites could translate into low-cost commercial mass-production capabilities of microsatellites  and  complementary GPS navigation equipment.
