Abstract
Collaborative local positioning techniques, such as could be used with smart phones, surveying equipment, or other mobile devices, are described. The techniques include independent techniques for distance measurement between devices, the relative positioning of devices, and an absolute orienting of the devices without use of fixed anchor points and through on-will participation of the devices to provide privacy. Distances between devices are determined by use of a sequence of positioning signals, such as a magnetic signal, each of which include an identifier of the transmitting device, the amplitude of the signal as transmitted, and the position of the signal within the sequence. The amplitude of the positioning signal as received can be compared to the amplitude as transmitted to obtain a distance.
