| Abstract: | Based on airborne GPS measurement practice for some aircraft,this paper advances that the following three aspects to achieve centimeter-level accuracy of satellite-borne GPS orbit determinations for Chinese HY-2 ocean altimetry satellite：first,to select the appropriate antenna for capturing many GPS satellites in the visibility;secondly,to focus on the antenna installation location,so as to reduce multipath effects;thirdly,to select the appropriate GPS receiver for ensuring high-quality data of satellite-borne GPS measurements. |
