Abstract
Disclosed are a positioning system and a positioning method using a low earth orbit satellite. The positioning system using a low earth orbit satellite according to the present invention comprises a generation unit for generating, when a communication period with a ground control station is reached, a first telemetry signal including a time value according to a reference time used by a low earth orbit satellite; a confirmation unit for confirming, on the basis of a navigation signal received from a navigation satellite, the GNSS time used as a reference by the navigation satellite; an adjustment unit for adjusting the time value in the first telemetry signal so as to be synchronized with the GNSS time; and a transmission unit for broadcast transmitting a second telemetry signal, after the adjustment, so that a positioning receiver on the ground can determine the position by using the second telemetry signal.
