Abstract

This paper presents a new approach to resolve an ambiguity zone of carrier phase measurements of low power devices. It is based on a Time Difference Of Arrival method. It reliably resolves the ambiguities between two reference points and a transceiver. Simulation are based on a low-power state-of-the-art ZigBee radio architecture. The results show that with a ZigBee channel and 12 MHz sampling frequency it is possible to reliably measure distances from 25cm to 25m without phase ambiguities and with a standard deviation lower than 20cm.
