The NASA's Space Technology 3 mission (ST-3) will demonstrate, among others, the newly developed Autonomous Formation Flyer (AFF) technology.
Technology is currently available to support real-time on-board knowledge of the position of a low earth orbitor at the 5-15 meter level using the civilian broadcast GPS signal with sophisticated models and filtering techniques onboard the spacecraft.
This paper proposes an implementation of AFF that borrows technology from the Global Positioning System (GPS), using measurements of both r-f carrier phase and a ranging code.
