摘要： The present invention relates to a method and apparatus for selectively receiving a radio frequency (RF) signal which utilizes an array of antenna elements for receiving the RF signal, a navigational controller for determining a pointing vector from coordinate information, and beam-forming electronics connected to the array of antenna elements and the navigational controller for forming reception lobes. This apparatus and method are particularly useful in the context of a Global Positioning System (GPS) for selectively receiving RF signals from GPS satellites to determine location and timing information. In one embodiment of the present invention, the phase of the elements of the array are adjusted to form selective reception lobes and constructively amplify signals within these reception lobes, increasing the signal-to-noise ratio (SNR) with respect to noise or interference signals outside the lobes. The reception lobes are advantageously positioned such that RF signals that are desired to be received are within the lobes according to the pointing vector determined by the navigational controller.

摘要： The present invention discloses methods, apparatuses, and systems for eliminating auto- and cross-correlation in weak signal CDMA systems, such as GPS systems. The invention uses parallel data paths that allow standard correlation of signals in parallel with verification of the lock signal to determine whether the system has locked onto the proper signal within the scanned signal window. The invention can be made with multiple CPUs, a single CPU with dual input modes, on multiple IC chips, or as a single IC chip solution for small, low cost reception, downconversion, correlation, and verification systems.

摘要： A method for automatically reducing carrier acquisition and tracking thresholds for carriers received in orbit by a receiver accessing an orbital navigator inside or outside the receiver, wherein said receiver comprises at least one phase loop. The phase loop is used for carrier acquisition and/or tracking and 'pushed' by a fine speed aid, and compensates for the error between the actual speed and the computed speed. The carrier Doppler frequency search is carried out around a frequency prediction maintained by the fine speed aid from the orbital navigator.
