Navigation
Here are some common backup solutions:
- Inertial Navigation Systems (INS): No dependence on external signals, fast
response, and effective in situations with weak GPS coverage.
- Differential GNSS (DGNSS): Improves accuracy
- Maps: e.g. in mountainous or densely populated areas.
- Radio Navigation (VOR/NDB)
- Assisted GPS (A-GPS): Faster startup and better performance
9.10.2.6 Update and maintenance – aircraft equipment
Updating and maintaining your GNSS system is important to ensure it is
operating optimally and delivering accurate data.
By following the recommended procedures, errors are minimized, and the
system’s efficiency and safety are enhanced.
- Regular or automatic updates
- Periodic calibration
- Monitor signal strength and quality.
- Watch for errors and irregularities in the position determination,
- Implementation of backup systems:
- Education and training in use and maintenance
9.10.2.7 Aviation regulations regarding GNSS systems
ICAO establishes standards and recommendations for the use of GNSS in
aviation. This includes requirements for precision, accuracy and redundancy.
EASA Implements specific procedures for the use of GNSS in aircraft operations,
including approval of navigation systems and training of pilots.
