METHOD FOR POSITION FINDING RELATIVE TO AN ANCHOR NETWORK USING UNIDIRECTIONAL COMMUNICATION

Abstract: the application relates to the position finding of an active or passive radio node against a network of at least two anchors, the object of the present invention is to make such methods simpler, more reliable, more flexible and/or faster. this can be achieved in particular by dispensing with time synchronization between the anchors and the radio node, while the anchors are time-synchronized with one another. in addition, the necessary communication can be further reduced by unidirectional ranging. a unidirectional transmission with frequency change from the radio node to at least two anchors or from at least two anchors to the radio node is sufficient. by contrast with the known unidirectional ranging between an active and a passive object, time synchronization between active and passive objects can be dispensed with if either two time-synchronized active objects or one active and two time-synchronized passive objects are used.
