The article covers issues of detecting the space object location in the near-Earth space
using the optical ground stations measurements. The work describes the algorithm of
searching the object status vector when the object is moving in the double visibility pick-
up range of the optoelectronic space surveillance
stations within a short time period. We
show the technique of defining the velocity vector by coordinate vectors obtained through
the triangulation method. The methods of approximation and filtering individual meas-
urements from optical ground stations as well as the method of evaluating the quality of
measurement sessions are discussed. We demonstrate the results of navigational data
processing with an example of a few geostationary objects and compare the orbital pa-
rameters obtained with the standard ones. The conclusions are drawn about the reasona-
bility and conditions of using the method of defining the object trajectory when the object
is in the double visibility pick-up range of the ground
stations. The article suggests the
ways to increase the precision of the solutions obtained.
