Determination of Dynamic Parameters of a Group of Space Debris Objects in Geostationary Area According to Positional and Photometric Measurements
摘要
A technique for joint use of positional and photometric measurements to determine the dynamic parameters of space debris (SD) objects is given. We present the results of its application to the assessment of the dynamic parameters of the motion of a group of objects in the geostationary area (GSA) based on observations made on the Zeiss-2000 telescope at the Terskol Observatory Center for Collective Use of the Institute of Astronomy of the Russian Academy of Sciences. We pay great attention to the problem of rejecting measurements, taking into account the specifics of presenting observations of SD objects. The determined parameters include the state vector of the object (coordinates and speed) at a given epoch, the value of the average object windage, the change in the area of its midsection and an approximate mass assessment.
