Abstract
We optimized orbital elements to minimize the squared deviation of the satellite position intermittently measured by an on-board GPS receiver from the satellite position measured from orbital elements using the SGP orbit model, and then reentered the results into the SGP orbital model to attempt an interpolation calculation of the satellite position and velocity at any given point in time. As a result of applying this system to data from a GPS receiver on board the Whale Ecology Observation Satellite (WEOS), we found that by using positions measured at several minute intervals over a period of about 2 hours, we could calculate the position of WEOS with an error of about 50 m at any given instant within the time frame, among other conclusions. © 2007 Wiley Periodicals, Inc.

利用星载GPS接收机确定卫星轨道要素及其验证
利用SGP轨道模型优化星载GPS接收机间歇测得的卫星位置与轨道元测得的卫星位置的平方偏差最小，然后将结果重新输入SGP轨道模型，尝试插值计算任意时间点的卫星位置和速度。将该系统应用于鲸鱼生态观测卫星(WEOS)上的GPS接收器的数据，我们发现，通过在大约2小时的时间内以几分钟间隔测量的位置，我们可以计算出WEOS在时间框架内任何给定时刻的位置，误差约为50米，以及其他结论。©2007 Wiley期刊公司电子工程学报，2009,31 (8):1010 - 1019,2007;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecja.20378
