    摘要： Disclosed is a method and apparatus for processing signals in a satellite/laser positioning system capable of generating location coordinates from received satellite signals and a received laser signal. A height coordinate bias value is maintained by a filter processor during periods when the laser signal is available. The height coordinate bias value represents an estimated difference between a satellite signal derived height coordinate and a laser signal derived height coordinate. During periods when the laser signal is available, the laser signal derived height coordinate is output. During periods when the laser signal is not available, a corrected height coordinate value is generated by applying the height coordinate bias value to the satellite signal derived height coordinate.

    摘要： Upon reception of four GPS signals from GPS satellites and determining four pseudo ranges, along with ephemeris data previously stored in the GPS receiver, the location of the GPS receiver and real time clock time error is determined. The GPS receiver is in possession of four pseudo ranges and determines four unknown coordinate values (x, y, x, and time) identifying the location of the GPS receiver and real time clock error. The process of solving for four pseudo range formulas simultaneously with each pseudo range formula having an unknown 'x', 'y', 'z', and time coordinates of the GPS receiver, results in identification of the coordinates and time of the GPS receiver. In a similar process, the GPS receiver receiving four GPS signals from four GPS satellites is able to determine four pseudo ranges. Using the four peudo ranges, four pseudo range equations unknown values for 'x', 'y', 'z' and time can be solved for simultaneously. The resulting values are then used to verify that the calculated positions of the GPS satellites are within 0.5 ms of the previous solution. If the GPS satellites are within 0.5 ms range of the prior solution then the real time clock error is estimated. Thus, using ephemeris data, the location of the GPS receiver is determined in a fraction of the time it takes to acquire the GPS satellites using conventional approaches.

    摘要： The invention relates to a method and a device for magnetic guidance, especially for tracking targets. The guidance is carried out in relation to the axis (1) of the beam of a monopulse antenna, by means of coding in the beam space. The coding process is carried out by appropriately modulating the signals radiated by the sum pattern (Σ) and the difference pattern (Δ). The receiving elements provided in the device are able to determine the position of said device in relation to the radiation pattern of the antenna, and can therefore determine its position in relation to the axis of the antenna. This position is determined by demodulating the signals received by the receiver. The invention is particularly suitable for guiding missiles or smart munitions in any quantity, for example for tracking targets.
