联合美国 / 法语 Jason-1 卫星高度表使命,在 2001 年 12 月 7 日从范登堡空军基地发射了,作为跟随上继续厘米级的海洋地形学观察的时间系列到高度成功的 T/P 雷达高度表卫星。轨道错误特别光线的轨道错误是在所有高度表卫星使命的全面预算的一个主要部件,以便继续观察的 T/P 标准。Jason-1 有 2.5 厘米的一个光线的轨道错误预算要求。在这个工作, Jason-1 机载的 GPS 数据的二个周期(到 2003 年 1 月 7 日的 2002 年 12 月 19 日) 被处理用零差别(ZD ) 动态精确轨道决心(邮政部门) 技术。产生 Jason-1 轨道精确性被比较与 JPL,轨道重叠和 SLR 剩余生产的精确轨道位置推算历(POE ) 估计。这些评估显示 RMS 光线的精确性在 1 2 厘米的范围。
The joint US/French Jason-1 satellite altimeter mission, launched from the Vandenberg Air Force Base on December 7, 2001, continues the time series of centimeter-level ocean topography observations as the follow-on to the highly successful T/P radar altimeter satellite. Orbit error especially the radial orbit error is a major component in the overall budget of all altimeter satellite missions, in order to continue the T/P standard of observations. Jason-1 has a radial orbit error budget requirement of 2.5 cm. In this work, two cycles (December 19, 2002 to January 7, 2003) of the Jason-1 on-board GPS data were processed using the zero-difference (ZD) dynamic precise orbit determination (POD) technique. The resulting Jason-1 orbit accuracy was assessed by comparison with the precise orbit ephemeris (POE) produced by JPL, orbit overlaps and SLR residuals. These evaluations indicate that the RMS radial accuracy is in the range of 1-2 cm.
