    Abstract: A method for eliminating or reducing interference in a receiver, for example, interference in a satellite positioning system receiver caused by a co-located TDMA transmitter, including detecting (210) the presence of a jamming signal, generating a synchronous blanking signal (220), and reducing the jamming signal by blanking (230) the receiver with a blanking signal. In one embodiment, the jamming signal is detected in the receiver, for example, at a correlator output of a satellite positioning system receiver.

    Abstract: A method and apparatus for determining time in a GPS receiver is provided according to the invention. The method includes the steps of capturing (304) GPS data in a GPS message for a predetermined period of time, locating (308) a predetermined data sequence in the captured data, and determining (311) a time offset between a data capture start time and a time of arrival of the expected data pattern.

    Abstract: Un método para determinar el tiempo en un receptor de Sistema de Posicionamiento Global (GPS), incluyendo capturar (304) datos GPS de un mensaje GPS durante un período de tiempo predeterminado; caracterizado por: localizar (308) una configuración de datos esperada en dichos datos GPS capturados correlacionando los datos capturados con la configuración de datos esperada; y determinar (311) un tiempo desfasado entre un tiempo de inicio de dicho período de tiempo predeterminado y un tiempo de llegada de dicha configuración de datos esperada, donde dicho mensaje GPS es de un satélite GPS y donde el paso de determinar incluye corregir dicho desfase de tiempo para compensar un tiempo de propagación de señal entre dicho satélite GPS y dicho receptor GPS y donde el paso de corregir incluye modificar dicho desfase de tiempo corregido para compensar un tiempo desfasado de reloj de satélite.
