Abstract

A method for determining a clock drift comprises determining a drift of a clock relative to a reference clock based on two signals from the reference clock and a further signal. The method can be used for time synchronization and is suitable for implementation on resource-constrained devices. An anchor point implementing the method and a real-time locating system comprising such an anchor point are also disclosed.
