    Patent number: 5821898
    Abstract: The invention relates to a method and an apparatus for codeless GPS positioning. According to the method, the unit (2) to be positioned receives GPS signals from several satellites (4), the codes of the GPS signals are removed, and the extracted carrier signals are transmitted out from the unit (2) to be positioned for the purpose of determining the position and/or velocity of said unit (2) to be positioned. According to the invention, the carrier signal frequencies are detected by means of a phase-locked loop and the thus detected signals are transmitted in digital format out from the unit (2) to be positioned for the purpose of further processing.
