FIELD: physics; transportation.
SUBSTANCE: method of inertial navigation consists in application of self-oscillation linear accelerometers, by indications of which: Δni=n1i-n2i, ni=n1i+n2i=fcTi and Nai=Δni/ni=Kaiai, (i=1...∞), proportional to acceleration and self-oscillation period Ti, where Kai=ml/KtsI0 is accelerometer transformation coefficient, ml is pendulous braking of accelerometer moving system, Kts and I0 is torque sensor transfer constant and current supplied by stabilised source; simultaneously with object acceleration time interval ni=fcTi is measure to measure acceleration, by accelerometer indications the components of velocity vector and of radius vector in direction of accelerometer sensitivity axis within this interval. To detect components of velocity vector Nvi and of radius vector Nri the accelerometer values Nai and ni for each self-oscillation Ti are multiplied and results of certain path segment are added.
EFFECT: reduced time of navigation data preparation and reduced number of applied means due to expansion of linear accelerometer functionality.
