    • The invention relates to a locating method and an arrangement for determining the location of a terminal (12) in a radio system comprising a plurality of base stations (10, 11) and terminals (12). At least two base stations (10, 11) with known locations transmit a signal used in locating the terminal (12), and the signals are transmitted in beams (13, 14) with directional antenna patterns and the direction of the beams (13, 14) is changed as a function of time. The terminal (12) determines the location of the base station (10, 11) and the transmission direction of the signal used in location determination by means of the beam (13, 14) transmitted by said at least two base stations (10, 11). Since the terminal (12) is located at the intersection of the beams (13, 14) of the base stations (10, 11) transmitting from known locations, the location of the terminal (12) can easily be determined. The solution takes multipath propagation into account.

    • A system and method for navigation utilizes sources of modulated celestial radiation. A spacecraft, satellite, or other vehicle (12) has one or more modulated radiation sensors (22a-22x) mounted thereto for detecting a modulated signal (14) generated by one or more pulsars or other celestial objects (16). A timer (24) measures the pulse time of arrival at a respective pulse sensor (22a­22x) by comparing the pulse signal (14) with a known pulse profile, and a processor (30) calculates a timing difference between the measured pulse time of arrival at sensor (22a-22x) with a calculated pulse time of arrival at a selected reference point (100). The positions and pulse profile characteristics of the pulsars (16) are stored in a digital memory (34) and combining the calculated time difference with the known positions of pulsars (16), the navigational parameters, such as position, velocity, and attitude, for spacecraft (12) with ,respect to the selected localized reference point (100) can be calculated.
