8. 3 bearing fix
$15.00 AUD
The three-bearing (or point) fix is the mainstay of traditional position fixing. It is an important technique to master to find out where you are WITHOUT your GPS, or at the very least, check the accuracy of your GPS unit.
By taking three bearings on widely spaced objects, we increase the accuracy and can easily spot an error, over two objects/bearings. Invariably, the three bearings will not cross perfectly but provide a ‘cocked hat’ or a ‘witches hat’ detailed in the following videos.
Includes:
- Video 1: Diagrammatical video of images, with a step-by-step technique for plotting the 3-bearings
Video 2: Actual plot on the chart - Cocked Hat information
- Practice
