medium Earth orbit

Grace was the first to derive the code generators used by the Galileo validation satellites and the first Compass satellite in medium earth orbit.

格蕾丝是首个破解伽利略试验卫星和北斗一代地球中轨道卫星所使用的编码规则的人。

A Combined environment which consists of charged particle radiation and ultraviolet ( UV) radiation exists in the medium and high Earth orbit.

在中高轨道上，存在着带电粒子辐射、紫外辐照等组成的综合辐射环境。

The paper begins with a brief outline on the recent status of geosynchronous and low/ medium earth orbit satellite communication systems.

本文先全面说明同步卫星和低/中轨道移动卫星通信系统的最新动态。

Based on the functionality and traffic characteristics of the Medium Earth Orbit Tracking and Data Relay Satellite System ( MEO-TDRSS), the coverage properties and Inter-Satellite Link ( ISL) performances of four familiar satellite constellation schemes which are adopted as the MEO-TDRSS of China are simulated and compared.
