WebHDOP is calculated mathematically from the positions of the satellites and at the same time, at the same place HDOP is the same for all receivers. They may be some difference if the receivers have decided to use different satellites for computing the position but anyways DOP values indicate only what accuracy is possible to achieve with current ... WebINTRODUCTION 1. Navigation is a process involving three steps: 1.1. Establish the track that needs to be followed (i.e. Flight Plan). 1.2. Establish current position relative to the FP. 1.3. Execute all necessary guidance actions to correct any deviation in position. 2. There are different types of navigation system: 2.1. Pilotage. Using visual ground references.
