 | Navigation difficulties of this type are usually detected by a divergence between the navigation systems, a situation that often occurs gradually. |
| Omega is a radio navigation system that uses a worldwide network of VLF signals from eight ground-based transmitters. |
| Omega equipment operations should be closely analyzed to ensure that an unacceptable workload is not imposed upon the flightcrew by use of the Omega equipment in normal and abnormal operations. |
| Satellite navigation system (1204 words) |
| Satellite navigation receivers reduce errors by using combinations of signals from multiple satellites and multiple correlators, and then using techniques such as Kalman filtering to combine the noisy, partial, and constantly changing data into a single estimate for position, time, and velocity. |
| The same applies to the use of smart bombs: the operator of a satellite navigation system can effectively degrade the performance of smart bombs being used by other states using its satellite navigation system to that of gravity bombs, or even offset them from their targets in such a way as to render them useless. |
| The best known satellite navigation system is the United States' Global Positioning System (GPS), and as of 2002 the GPS is the only fully functional satellite navigation system. |
