Determination of the Preliminary Orbits of Artificial Satellites From Observations With Time Approximately Known

Twentieth-century milestones in the history of the Russian ephemeris service: Marking 100 years of the Calculation Institute and astronomical yearbook

“…He also developed a method to determine the AES orbits from optical observations which had time errors. 30 Together with D. K. Kulikov, he published the method to improve the parameters using data obtained from such observations of orbits previously found. 31 Few years later, he published a method to determine the Earth's gravitational field from the motion of the resonant AES (1965).…”

“…Kranjc (136) proposed a slowly converging method of chords that circumvents the problems encountered in the orbit determination of objects on circular orbits. Batrakov and Kulikov in two articles (13,139) suggest a Herrick-Gibbs method that includes the possibility of errors in reckoning the time of observation-both the generation of preliminary orbits and a modified differential correction technique are developed. Finally, in the application of orbit determination to lunar (or interplanetary) space vehicle orbits, Kizner (123) proposed a set of orbital parameters related to osculating elements of the terminal hyperbola near the moon.…”
