第一台可搬运激光测距系统,目前已在太平洋东岛基地运转。这种由美国航空和航天局哥达德宇航中心研制的TLRS-2卫星跟踪系统,是为尽快部署到世界上各个边远地区而设计的。其跟踪精度是2厘米。该系统监测卫星轨道并提供地壳变动的有效测地数据。航空和航天局的德格南(Degnan)说:“该系统
The first portable laser ranging system that is currently operating at the Pacific Island base. The TLRS-2 satellite tracking system, developed by NASA’s Goddard Aerospace Center, was designed to be deployed to remote areas of the world as quickly as possible. The tracking accuracy is 2 cm. The system monitors satellite orbits and provides effective geodetic data on crustal movements. NASA Degnan said: ”The system
