This paper introduces a GPS data processing software, OMNI, developed by National Geodetic Survey of U. S. , in particular, its strong ability of cycle slipfixing.
The fixing sleeve is made of an elastic material, and the two ends of the support bar and the fixing sleeve are in slip connection with the supporting transverse rods.
紧固套由弹性材料做成，支撑杆与紧固套两端与支承它们的横杆滑动连接。
