The article discusses the use of a Kalman Filter (KF) in tracking components of GPS meta-signals using bicomplex numbers.

It highlights the benefits of using a triple-loop architecture, which can be improved by incorporating a KF, due to the related dynamics experienced by the code, carrier, and subcarrier components.

The article also mentions previous work showing that components from two different RFs can be effectively represented using bicomplex numbers, and the potential of a KF to significantly improve receiver performance under dynamic conditions.
