地理坐标系 [测] geographic coordinate system
- 如何将GPS位置实时推算至海底地形点位置、获取海底测点在地理坐标系中的精确位置是一套十分复杂的计算过程。
It is complicated procedures that how to transfer the location of GPS to accurate survey point on sea-bed in geographic coordinate system. - 地理和投影坐标系都包含对地球形状的假设(一个略扁的球体);这称为大地基准点。
Both geographic and projected coordinate systems include a definition of the assumed shape of the earth (a flattened sphere); this is called the geodetic datum. - 稳定回路是控制平台姿态的闭环回路,它同修正回路共同作用使平台稳定跟踪当地地理坐标系。
The servo loop is a position stabilization loop of the platform. Revise loop help it to command the platform into alignment with the local present coordinate system.
