英文摘要 | It is shown, by simulated calculation, that the reference vector algorithm we proposed of calculating initial orbits is "quasi-optimal", because its accuracy approaches the Cramer-Rao lower bound in the statistical theory of estimation and is proportional to the observing error. Double solution exists in the orbit calculation: the smaller the eccentricity and the closer the mean anomaly Mo is to +/-90 degrees, the greater is the probability of getting the false solution. We propose an algorithm which gives two solutions, one of which must be the true one and it has a high accuracy. |
