Area navigation computer and solid state filter |
| abstract |
A solid state filter for area navigation computers and similar avionics equipment which rejects errors commonly resulting from VOR course scalloping and multipath effect on signal propagation between the ground station and an airborne receiving unit. The subject filter operates to sense the rate at which the ground station signal phase is changing and adds a compensating signal thereto in the receiving unit. As a result, the ground station signal can be filtered with a long time constant to reject course scalloping and other errors while, at the same time, compensating for the resulting aircraft position lag. The amount of course scalloping rejection can be increased until limited by the desire to maneuver the aircraft. |
