METHOD OF DETERMINING THE LOCATION OF SHORT-PULSE ALTITUDE SOURCE OF X-RAY RADIATION BY MEANS OF COSMIC BASIS Russian patent published in 2017 - IPC G01S11/00 

FIELD: physics.

SUBSTANCE: with the help of devices installed on a spacecraft (satellite), x-ray pulses from the source and optical fluorescence radiation coming from the direction into the nadir are recorded. Optical fluorescence radiation occurs as a result of exposure to X-rays from the source to the atmosphere. The time and direction of arrival of the x-ray pulse and the time of arrival of the optical pulse from the nadir are recorded. In this case, the angle between the directions to the source and the nadir is measured. The difference in arrival times of the pulses from the direction to the source and from the nadir is measured. From the measured time difference and from the measured angle between the directions to the source and to the nadir, at a known altitude of the orbit of the spacecraft, the source height and the distance between the spacecraft and the source are determined.

EFFECT: increasing the accuracy of determining the location of the X-ray source, eliminating the dependence of measurements on meteorological conditions.
