Navigation to a target
UDI-
14™ can be used to track an SOS beacon or a Homing beacon.
A homing beacon transmits a homing signal from the boat unit on a specific dedicated frequency. An SOS
beacon transmits a homing signal on a specific frequency, received on all networks used with UDI-
14™.
Navigation using the UDI-
14™ can be done only while the diver or beacon is moving in relation to each
other. In other words, the UDI-
14™ diver, the beacon, or both must be moving, since the navigation
beacon relies on the Doppler Effect.
Navigation method for tracking:
Correct navigation as you dive showing the adjusted direction of the target beacon on the UDI-
14™.
Choose a random initial direction to start diving, and then adjust as you go.
1. Starting location of diver
3. Beacon location
2. Course adjustments
