Method and device for generating a location signal

A method for generating a location signal, the method comprising:

• receiving, from a reference device, at least one location signal control parameter that defines linear frequency slope characteristics for a calibrated location signal;
• setting, to a calibrated state, internal processing of a device that generates the calibrated location signal, wherein the calibrated state generates a calibrated time delay within the device, wherein the calibrated time delay comprises a steady state internal processing delay for the device;
• configuring a frequency generation unit (FGU) of the device to generate a first current having a first magnitude and a first polarity that are based on the at least one location signal control parameter;
• and
• for at least one iteration:
• during a first time period set based on the at least one location signal control parameter, charging a capacitive element in the FGU with the first current to generate a first control signal;
• coupling the first control signal to a voltage controlled oscillator (VCO) to generate a first part of the calibrated location signal having the defined linear frequency slope characteristics;
• transmitting the first part of the calibrated location signal;
• configuring the FGU to generate a second current having a second magnitude that is based on the at least one location signal control parameter, wherein the second current has an opposite polarity from the first polarity;
• and
• for at least one iteration:
• during a second time period set based on the at least one location signal control parameter, charging the capacitive element with the second current to generate a second control signal;
• coupling the second control signal to the VCO to generate a second part of the calibrated location signal having the defined linear frequency slope characteristics;
• transmitting the second part of the calibrated location signal directly following transmission of the first part of the calibrated location signal.

A device for generating a chirp signal, the device comprising:

• a transceiver for receiving, from a reference device, at least one chirp signal control parameter that defines linear frequency slope characteristics for a chirp signal;
• a frequency generation unit (FGU) coupled to the transceiver and comprising:
• a current source having variable gain,
• an adjustable filter with a capacitive element for wideband operation;
• a voltage controlled oscillator (VCO);
• and
• chirp generation control circuitry that configures, based on the at least one chirp control parameter, the gain and a polarity of the current source to generate a first current during a first time period for charging the capacitive element to generate a control signal that is coupled to the VCO to generate a first part of the chirp signal having the defined linear frequency slope characteristics, wherein the first part of the chirp signal is transmitted using the transceiver.
