The phenomenon of space Charge Accumulation (SGA) of spacecraft will exhibit if it operates at its orbit-especially at high altitude orbit.

航天器表面在轨道运行中会出现电荷积累现象，尤其高轨道航天器这种现象更为严重。

When navigation accuracy is highly expected , the sensor with higher accuracy should be chosen and the observation time should be longer , especially in high - altitude orbit.

当对导航精度要求较高时，轨道越高，尤其在高轨道类型中，应尽可能的选择精度高的敏感器以及尽量长的观测时间。

The charge accumulation phenomenon on the surfaces of a spacecraft at a high altitude or geosynchronous orbit would appear.

处于空间电环境条件下的航天器表面会出现电荷积累，形成高的电势值。

Alongside the HTC-made handset are an altitude and orbit control system, two propulsion setups and a Linux-based computer with a "high-speed" processor.
