| 摘 要： | 针对海洋二号（HY-2）卫星如何实现厘米级定轨问题,提出下列建议：海洋二号卫星不必采用DORIS定轨;给海洋二号卫星装备无电功耗需求的激光后向反射镜阵列,以便对它进行多个SRL测站观测的激光厘米级定轨;给海洋二号卫星装备具有双频载波相位测量能力的GPS信号接收机,实现高精度的星载GPS测量定轨.

| Abstract: | Chinese HY-2 satellite will get in engineering research phase in near future.In order to acquire precise dynamical data of ocean observing,it is necessary for Chinese HY-2 satellite to have accurate orbit parameters.This paper suggests how to make-level orbit determinations as follows: to use DORIS orbit determination is not suitable for Chinese HY-2 satellite;to equip laser retroreflector array not requiring electro-power at satellite surface,so as to carry out laser cm-level orbit determinations using several SLR stations;to fit out the satellite-borne GPS receiver that has the ability surveying GPS carrier phases of tow frequencies,achieving cm-level orbit determinations by means of several ground reference stations. |
