An improved satellite aided vehicle avoidance system (SAVAS) is described. The exact range from a protected vehicle to an intruding vehicle with mutual-collision heading and velocity is derived without signal transmission by the protected vehicle or use of synchronized time reference devices. Additional steps of measuring time-to-collision from the delay and Doppler measurements, establishing ordered time-slots from the form of the satellite signal may be included. measuring time-to-collision from the delay and Doppler measurements, establishing ordered time-slots from the form of the satellite signal may be included.
