Beschreibung
Zusammenfassung:	The invention discloses a large airspace relative navigation method and device for catastrophic events quick rescue, wherein the navigation method comprises the following steps: S1, acquiring the position coordinates of moving objects M1 and M2 by using satellite navigation data received by a GNSS receiver, and obtaining the relative coordinates between the moving objects M1 and M2; S2, based on the relative coordinates between the moving objects M1 and M2, calculating the radial distance and relative position between M2 and M1 in the rectangular coordinate system of the measured point; S3, according to the radial distance and relative position between the moving objects M1 and M2, judging the relative motion relationship between them; and S4, judging the relative position change between the moving objects M1 and M2 according to the relative motion relationship between the moving objects M1 and M2.
