Abstract
A measuring and transmitting system of measuring signals for the deflection of an interior frame angle of a position gyro cardanically mounted in an exterior housing, in which the position gyro has an interior frame and an exterior frame, is provided with a gyro rotor and a permanent magnet in the gyro rotor. The permanent magnet forms a signal generator of the interior frame, and has a magnetic field generator center. A plurality of measuring coils form a signal receiver formed on the exterior frame, the measuring coils having measuring axes aligned in parallel to one another and eccentrically with respect to the magnetic field generator center. An analysis unit is connected behind the measuring coils and performs a measuring signal analysis.

A measuring and transmitting system of measuring signals for the deflection of an interior frame angle of a position gyro cardanically mounted in an exterior housing, the system comprising:
- an interior frame and an exterior frame for the position gyro;
- a gyro rotor of the position gyro;
- a permanent magnet arranged in and rotating with the gyro rotor, the permanent magnet forming a signal generator of the interior frame, and having a magnetic field generator center;
- a plurality of measuring coils forming a signal receiver formed on the exterior frame, the measuring coils having measuring axes aligned in parallel to one another and eccentrically with respect to the magnetic field generator center;
- and
- an analysis unit connected behind the measuring coils and which performs a measuring signal analysis.
For use in a measuring and transmitting system of measuring signals for measuring a deflection of an interior frame angle of a position gyro cardanically mounted in an exterior housing, the method comprising the step of:
- replacing a measuring signal for the interior frame angle .alpha. by an axis-related signal u.sub.y according to the formula u.sub.y =.alpha..multidot.sin .PSI., wherein .PSI. is an exterior angle.
