public interface GNSSAttitudeProvider
extends AttitudeProvider
```
Attitude providers for navigation satellites.
The attitude mode is compliant with IGS conventions for spacecraft frame, i.e. the +Z axis is towards Earth and the +X axis is in the Sun direction. This may be different from some manufacturers conventions, for example for GPS blocks IIR/IIRM whose X axis convention is opposite.
