Abstract:
1. A method for determining a vertical on moving object including in one of the two channels, at least, the following steps: determining an apparent acceleration in a plane to be chosen, it passing through mutually perpendicular axes of a platform, whereon accelerations being determined, one of which being a vertical axis and another being a chosen axis, for example, parallel longitudinal axis of the moving object, in particular, being superposed with the said longitudinal axis, determining one of the accelerations in the said chosen plane, for example, horizontal acceleration being a part of the said apparent acceleration, determining the difference of the said accelerations, in particular, the said apparent acceleration and the said horizontal acceleration, changing the polarities of the said accelerations in the case of changing the polarity of another acceleration, in particular, vertical acceleration one being also part of the said apparent acceleration, determining a gravitational vertical by the said difference, in particular, by means of bringing the said difference up to zero.
