Claim:
1. A system for tracking of a received signal with at least one subcarrier, wherein the received signal represents a carrier signal modulated with a code signal and modulated with a subcarrier signal, wherein the system comprises the following independent and cooperatively operating loops: a phase lock loop for tracking the carrier signal; a subcarrier lock loop for tracking the subcarrier signal, which comprises a first controllable oscillator and one of an early-minus-late discriminator or a first arctan discriminator, for generating a control signal for the first controllable oscillator, wherein one of a delay lock loop for tracking the code signal, which comprises a second controllable oscillator and a second arctan discriminator for generating a control signal for the second controllable oscillator, wherein one of
