    摘要: A system, particularly a local railway system, and a method for the in-vehicle track detection for such a system. The invention relates to a system, particularly a local railway system, and to a method for the in-vehicle track detection for such a system. The system comprises vehicles moving along a track system (7), on which at least one location identification (1) is firmly attached on the track side, the location identification having a transmitter device and transmitting its identification to the vehicles by emitting a signal containing the identification via the antenna of the transmitter device, the emitting characteristic (2) of which comprises a main lobe (3), wherein the vehicles detect the passage of the location identification (1). In order to reduce any errors in the in-vehicle location determination, it is proposed that the location (O) of the transmitter device, and therefore of the location identification (1), is the mean location between the two locations (11, 12) at which the signal of the main lobe (3) initially exceeds, and subsequently falls below, a predetermined threshold value while passing.

    摘要: Es wird ein Verfahren und eine Vorrichtung zur Bestimmung der relativen Ausrichtung von Fahrzeugen im Straßenverkehr beschrieben. Hierbei werden Funksignale empfangen und ausgewertet, die von diesen Fahrzeugen an das Umfeld gerichtet sind. Die Funksignale werden mit Richtungsinformationen moduliert und zyklisch in unterschiedliche Richtungen vom Fahrzeug abgestrahlt. An den verschiedenen Standorten werden dann die Empfangsfeldstärken dieser Funksignale zusammen mit ihren Richtungsinformationen ausgewertet und Werte für die relative Ausrichtung des sendenden Fahrzeugs gewonnen.

    摘要: Independent guidance and monitoring to be integrated into an MLS landing system and also provides a scaled-down MLS landing guidance system useable at small airports. In both cases an added fixed beam precision guidance system is integrated into the MLS time sequence format. The fixed beam guidance system is based upon the concept of using paired fixed overlapping beams (31, 32 and 33, 34), sequentially radiated by different fixed antennas (80, 81 and 89, 90). One pair (31, 32) is oriented to left and right of the centerline (36) of the runway, and the other pair (89, 90) is oriented above and below the desired glideslope (36'). The first set of paired beams overlap at the centerline (36) of the runway in such a manner that an aircraft approaching exactly on centerline (36) will intercept equal signal intensities to indicate and on-course approach. Conversely when the aircraft is off-course to one side of the centerline (35), it will intercept a stronger signal intensity for the fixed guidance beam (31) which is directed to that side of the centerline and a weaker signal intensity for the fixed beam (32) which is directed to the other side of the centerline. Similar operation is provided by the overlapped guidance beams (33, 34) operating in the elevation mode.
