    Abstract: Systems and techniques are disclosed relating to wireless communications. These systems and techniques involve wireless communications wherein a device may be configured to recover an information signal from a carrier using a reference signal, detect a frequency error in the information signal; and periodically tune the reference signal to reduce the frequency error. To prevent GPS performance degradation during LO tuning, a tuning indicator signal may be generated and provided to the GPS receiver to disable GPS operation.

    Abstract: A mobile communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.

    Abstract: Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are described. In an aspect, a terminal informs a location server of service capabilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid requesting unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

    Abstract: Un procedimiento (400) para determinar una solución de navegación que comprende: obtener información del sistema de navegación inercial, INS, a partir de uno o más orígenes en una primera época; almacenar (420) dicha información del INS obtenida en la primera época, en la que la información del INS almacenada no es suficiente para calcular una solución de navegación; y obtener (440) en una segunda época posterior a la primera época una segunda parte de información, que permite determinar una ubicación de inicio donde se tomó la información del INS almacenada, comprendiendo la segunda parte de información información de posición de uno o más orígenes de los sistemas de localización por satélite, SPS, en el que la obtención (440) es en respuesta a un entorno de señal cambiado y/o a una vista cambiada al uno o más orígenes; correlacionar la ubicación de inicio con un tiempo registrado en el cual se tomaron las mediciones del INS; y extrapolar una posición usando el tiempo registrado y dicha ubicación de inicio donde se tomó dicha información del INS, en base, al menos en parte, a la información del INS almacenada.
