gps-bearing calculates the bearing and distance from one WGS84 point (aka GPS position) to another. This is the kind of calculation needed for two directional antennas to point to each other, or a camera to point towards a specific target.

| Latitude (N): | |
| Longitude (E): | |
| Altitude: | |
| Hints: Type negative latitude angles for points on the southern hemisphere, and negative longitude angles for points in the west. Zero heading, pitch, and roll means that you are standing upright on a levelled surface, and facing north. |

Bearing and distance from your position to the target position
| Horizontal angle: | ? |
| Vertical angle: | ? |
| Distance: | ? |
Turn left (counter-clockwise, mathematical sense) by the indicated horizontal angle, and then up by the indicated vertical angle.
You are now looking towards the target.
