Title
(EN) DETERMINING VELOCITY USING A REFLECTED POSITIONING SIGNAL
(FR) DÉTERMINATION DE VITESSE À L'AIDE D'UN SIGNAL DE POSITIONNEMENT RÉFLÉCHI
Abstract
(EN)
Examples for determining velocity using a reflected positioning signal are presented herein. An example may involve a receiver receiving signals from satellites and identifying a particular signal that reflected off a reflecting plane prior to reaching the receiver. The receiver may then determine a reflected satellite position for a satellite that transmitted the particular signal. The reflected satellite position may be determined by reflecting a position of the satellite about the reflecting plane. The receiver may then determine a direction vector to the reflected satellite position for the satellite and determine its velocity using the determined direction vector.

L'invention concerne des exemples de détermination de vitesse à l'aide d'un signal de positionnement réfléchi. Un exemple peut impliquer un récepteur recevant des signaux provenant de satellites et identifiant un signal particulier qui est réfléchi par un plan réfléchissant avant d'atteindre le récepteur. Le récepteur peut ensuite déterminer une position de satellite réfléchie pour un satellite qui a transmis le signal particulier. La position du satellite réfléchie peut être déterminée par réflexion d'une position du satellite autour du plan de réflexion. Le récepteur peut ensuite déterminer un vecteur de direction vers la position de satellite réfléchie pour le satellite et déterminer sa vitesse à l'aide du vecteur de direction déterminé.
