Aerospace Instrument-Making Annotation << Back Investigation of the Influence of the Characteristics of On-Board Optoelectronic Equipment of Measuring Spacecraft on the Accuracy of Determining the Coordinates of a Space Object Using the Space Triangulation Method Fadin I.A., Pirukhin V.A., Gruzdev N.V. The article presents functional dependencies of the standard deviation of the estimated coordinates of a space object on the standard deviation of the angular measurements of the position of a space object by onboard optical-electronic instruments of observer spacecraft using the space triangulation method, which can be used both to substantiate the requirements for the target equipment of observer spacecraft and to select a method for determining the position of a space object. Keywords: space triangulation, ensuring the safety of space activities, optical space, error, average square deviation. DOI: 10.25791/aviakosmos.3.2026.1541 Pp. 13-19.
