Abstract—The orbit determination not only is the one of the main ways to evaluate the precision class of controlling the craft launching and separating satellite from rocket, but also the resource of guiding data for later observations. These different kinds of orbit differ greatly in field angle to the earth's core in equal time interval. So that will produce different effects on the result of orbit determination. Two projects are offered for a high-accuracy orbit determination in define observation data arc except choicing a site where the observation data arc may cover the perigee. One way is to lengthen data arc. The other is to add data kinds. Last those three methods are introduced and analysed in view of those two means.
