Method for generating a location signal

A method for generating a location signal comprising:

• receiving, in a communication device from a reference device, at least one location signal control parameter that defines pulse shape characteristics for a calibrated location signal;
• setting internal processing of the communication device to a calibrated state, wherein the calibrated state generates a calibrated time delay within the communication device, wherein the calibrated time delay comprises a steady state internal processing delay for the communication device;
• configuring a frequency generation unit (FGU) of the communication device based on the at least one location signal control parameter;
• starting at a first frequency and progressively sweeping an output of the FGU over a first range of frequencies to a second frequency, wherein the output is swept along at least one linear frequency slope having a first polarity to generate a first part of the calibrated location signal having the defined pulse shape characteristics;
• progressively steering the output back over at least part of the first range of frequencies from the second frequency to a final frequency, wherein the output is swept along at least one linear frequency slope having an opposite polarity from the first polarity to generate a second part of the calibrated location signal having the defined pulse shape characteristics;
• and
• sequentially transmitting the first and second parts of the calibrated location signal.
