Abstract:
1. A method for relative navigation and guidance of a vehicle comprising: obtaining, by a global navigation satellite system (GNSS) receiver, coordinates of a vector connecting two points in space using carrier phase measurements from a global navigation satellite system; setting the vector as an intended path of the vehicle; storing first carrier phase signals from the GNSS receiver received at a first position of the vehicle; receiving second carrier phase signals from the GNSS receiver at a second position of the vehicle; determining, by a processor, a current position of the vehicle relative to the intended path from the one or more second carrier phase signals received at the second position and the one or more first carrier phase signals received at the first position; and computing, by a processor, a distance between the current position of the vehicle and the intended path of the vehicle.
