  • the invention relates to a method for navigation and loading control of moving objects, in which measurement signals from a self-sufficient system on the object and measurement signals via antennas from a global satellite or radio navigation system, or also via optical devices, are used to Obtain movement data or location coordinates of the object with high accuracy and as a function of time.
  • the invention also relates to a device for navigation and movement control of objects, comprising sensors of an autonomous system on the object and antennas of a global satellite or radio navigation system, or also corresponding optical devices that supply measurement signals, computer devices to derive movement data from the measurement signals, Comparison devices for comparing movement data with one another and a controller device for minimizing comparison differences.
  • the antennas for the second measurement signals are either in the vicinity of this measurement location, but this inevitably leads to parts of the aircraft that are distant from the measurement location being ignored when navigating unless they are rigidly connected to it, which is not only the case with large aircraft and would be critical in taxi operations at airports.
  • the antennas for the second measurement signals are at a greater distance from the measurement location for the first measurement devices, then elastic deformations of the aircraft can reduce the accuracy of the determined location coordinates to such an extent that safe guidance of the aircraft is made impossible. In the case of larger aircraft, noticeable elastic deformations occur even with less turbulence when one thinks of wing spans of over 30 m.
  • the aircraft In all of the navigation methods known to date and used in practice, the aircraft is regarded as a rigid body despite these elastic deformations and changes in shape.
  • the present invention relates to a method and a device of the type mentioned at the outset, which are each intended to be applied to non-rigid objects.
  • a device for regulating the distances between a plurality of track-guided vehicles traveling in a column is known (DE-PS 24 04 884 C2), to which control circuits are assigned in each case, which track the vehicles to predetermined target positions by influencing the vehicle speeds.
  • the control circuits are connected to a central controller, which controls the target positions and target speeds individual vehicles calculated depending on their distances from one another and transmitted to the control circuits assigned to the vehicles.
  • the control circuits of the vehicles compare the positions of the vehicles assigned to them with the transmitted solo positions and correct the target speed if the difference between the target position and the vehicle position exceeds a predetermined tolerance value.

  • FIG. 2 shows a diagrammatic representation of the relative position of the GPS antenna and inertial measuring unit (IMU).

  • the currently most powerful navigation systems for rigid air, water and land vehicles consist of a combination of sensors with high availability (especially inertial sensors, ie gyroscopes and accelerometers) and sensors with high long-term accuracy (so-called support sensors) such as satellite navigation receivers (e.g. for GPS and / or GLONASS), which are integrated into overall systems according to known principles.

  • the movement caused by u is described using the initially unknown state x.
  • a measuring system in the form of a satellite navigation receiver determines measured variables y derived from x (for example inclined distances J between the vehicle and the navigation satellites, cf. FIG. 2).
  • y derived from x
  • parallel to this process which is shown in the upper part of FIG. 1, building on u in the lower part in the navigation computer, a simulation of the vehicle movement (block "vehicle simulation") is carried out, which leads to an estimate ( ⁇ ) of x.
  • estimates for the measured values y are also generated based on this estimate with the aid of a measurement model (block “measurement simulation”).
  • the estimated and the actual measured values are then compared with one another and their difference is fed to a “controller”, which has the task of keeping the difference between the simulated, known and the actual, unknown quantities of x as small as possible.
  • the relative position of the inertial sensors and the satellite navigation antenna is influenced, for example, by structural vibrations of the vehicle.
  • these additional movements should not be neglected given the measurement resolution of the satellite navigation devices (cm range) that is possible today.
  • the measured ⁇ is not primarily used for navigation Instead, the s determined from this is determined by 1.
  • the sensors for determining u and y are no longer concentrated in a few places, but many sensors are spatially distributed over the object and deliver corresponding sets of measured values.
  • the mechanical model of the moving, non-rigid object or vehicle for the vehicle simulation receives additional elastic degrees of freedom, degrees of joint freedom or the like. and therefore no longer represents a rigid body. This increases the number of differential equations and the components of x, which together describe the vehicle movement.

Abstract

Procédé de navigation et de commande de mouvement d'objets qui se déplacent. Ledit procédé consiste à recueillir des signaux de mesure provenant d'un système autonome situé sur l'objet et des signaux de mesure provenant d'un système de radionavigation ou de positionnement par satellite par l'intermédiaire d'antennes, ou par l'intermédiaire de dispositifs optiques (tels que des appareils de poursuite laser) pour obtenir des données de mouvement et plus spécialement des coordonnées de lieu de l'objet avec une grande précision et en fonction du temps. Lorsque ledit procédé est appliqué à des objets non rigides, des signaux de mesure provenant d'une pluralité de capteurs et d'antennes répartis sur l'objet et/ou des signaux supplémentaires de mesure provenant de sondes de mesure qui détectent les modifications d'écartement, les déformations ou les modifications de configuration (jauges extensométriques ou analogues) sont utilisés pour le calcul des données de mouvement et des coordonnées de lieu.
