Definitions
- the invention relates to a method for determining the Roll position of a rolling flying object, in particular for Guiding a ballistic flying projectile / missile with roll compensation.
- the roll position is determined by vitally important, provided that a subsequent steering of these flying objects should take place during the mission.
- this applies to the steering of ballistic flying projectiles / missiles, where the possibility a trajectory correction is provided, such as is described in P 44 01 315.9.
- the present invention is based on the object To develop methods of the type mentioned above which is a relatively precise determination of the roll position of the Flying object takes place and which only a little effort assumes.
- Direction reference A field strength vector of the earth's magnetic field is called Direction reference used.
- a magnetic field sensor measures the component of the Geomagnetic field preferably in the radial direction to / r Projectile / missile. Depending on the Roll position an alternating, sinusoidal course of a measured intensity, whose minima and maxima indicate that the measuring direction on the course of the earth's magnetic field on next one is. From the time interval of the maxima / minima the roll frequency is determined.
- the location of the magnetic field sensor is also the reference point for the rolling position.
- the roll axis of the obedient flying object is determined by the Approximate speed vector.
- the direction of the Velocity vector is known because it is either called Target course determined during mission planning and stored in an evaluation computer or during the Flight e.g. is measured with NAVSTAR-GPS.
- the orientation of the field strength vector is in advance known reference system and in one Evaluation computer saved.
- the roll position of the projectile / rocket for the times of the maximum or calculate the minimum intensity. Between these The rollage is determined with the determined times Roll frequency predetermined.
- the System dead time i.e. the time required for the evaluation Time, the accuracy of the roll position determination is additional increased.
- FIG. 1 is a flying object 1 with a Magnetic field sensor 2 and a measuring axis 3 shown.
- This Flying object has a speed vector 4 and one Roll axis 5.
- the arrow w represents the roll angle of the Flying object 1 with respect to a vertical reference axis (VRA) 6.
- a field line 7 of the Earth's magnetic field drawn with a field strength vector 8.
- the field strength vector 8 is used to determine the Roll position of the flying object 1, the Speed vector 4 of the flying object is known.
- the method of operation of the present method is the following:
- a time interval Tp between two maxima or two minima is the duration for one revolution of the roll Projectile / missile.
- the roll frequency is determined from this.
- the speed of the flying object 1 becomes independent of determined the full procedure. This happens for example via NAVSTAR-GPS (Global Positioning System), with the help of which position values of the / r Projectile / rocket and also speed determined become.
- NAVSTAR-GPS Global Positioning System
- Roll axis 5, VRA 6 and field strength vector 8 let the Determination of the roll position of a reference point, e.g. location of the Magnetic field sensor 2 at the time when the measuring axis 3 matches field line 7 as much as possible. Between The roll angle w is calculated in advance of these times from the roll frequency and the time span after the last one Reference measurement.
