Effects of Delay on Range Measurement Due to the Interplanetary Plasma for the Mars Probe

Journal: Hydrographic Surveying and Charting

Abstract: 根据Muhleman和Anderson在1981年给出的行星际空间等离子体密度模型,模拟计算了行星际等离子区对8GHz电波的距离延迟与太阳-地球-航天器夹角(SEP)和光路径长度(L)的关系.结果显示,在本文的模拟条件下,距离延迟随SEP和L从几毫米变化到几十米.最后,分别仿真了一条地火转移轨道和环火星轨道,计算了两种情况下行星际等离子区延迟对测站到航天器距离观测量的影响.
