The calibration of time-depending measurement uncertainties of gyros and inertial systems by the differences of angular and/or velocity and/or positional measurements which are carried out and repetitiously executed with a view to undetermined reference directions and/or fixed locations varying with time. The differentiation allows to forego precise reference data. Measurement uncertainties can be corrected through calibration subsequently to the measurement process. For the measurement of spatial angles a three-axis gyro measurement package comprising a computer and the possibility of feeding or automaticly reading-in of reference data characterizing the reference directions. The reference data can be a number, a marker of the measurement point or in the case of positional measurements a terrestrial aiming point. When measuring angular characteristics, i.e. the interdependence of angles and external forces or moments, the latter are considered as references. For the measurement of contours the distance has to be fed in or read in, or computed by accelerometers within an integrated inertial system, respectively. By such a system and through the application of the invention the measurement accuracy of movements and gravity anomalies can be increased while refraining from external references otherwise necessary under the present state of the art.
A method for measuring spatial angles at at least two different measurement positions by means of an apparatus including three gyros comprising the steps of:
