FIELD: space navigation. ^ SUBSTANCE: proposed method relates to determining security limit PLpos(t+öt) around moving body computed for future time interval t+öt from satellite data coming from constellation of satellites. Proposed method comprises selecting security threshold related with location in future time interval Pir, distributing said threshold between security threshold related with location Pir pos and that threshold related with speed Pir v. Then, location and speed is determined for moving body at given moment t, statistical errors related with location and speeds are computed for said given moment. Proceeding from results obtained and security thresholds related with location and speeds, determined are security limit, PLpos(t), related with location at given moment and security, limit PLpos(t+öt), related with speed at given moment to compute security limit so that where is maximum possible acceleration of moving body. ^ EFFECT: higher reliability of determination. ^ 6 cl, 2 dwg |
