Is it possible, in the absence of a real compass, to navigate the Sun and the shadows in motion, without long stops? Can. To do this, it is enough to spend 15-20 minutes and assemble the simplest device portable solar compass from improvised means.

The methods of orientation to the terrain using the Sun without the use of any instruments, such as watches with arrows, can be counted on the fingers of one hand. All of them, as a rule, are based on the use of shadow movement and have one significant drawback for determining the sides of the horizon, using such methods, it is necessary to be in the same place for 20 or more minutes. This causes certain inconvenience, especially if you are on the move and not in your best interest to make frequent and long stops.

I would immediately like to note that the more thoroughly and accurately you approach the process of manufacturing a portable solar compass, the more accurately it will show the sides of the horizon. For a more complete understanding of the operations performed, text and graphic explanations will be applied to large (enlarged) photos. To begin with, we define the sides of the horizon in a way that is well known and well described in various sources according to the Sun and shadow. For this it is necessary.

Determining the sides of the horizon by the Sun, branch and shadow.

one. Find or cut a flat branch with a knife. Some sources recommend its length of at least 1 meter, in fact, the length of its special value does not matter and affects only the waiting time for the passage of the shadow. The shorter the branch, the longer it takes.

2. We will sharpen the upper end of the branch with a knife and stick it on a flat, preferably free from vegetation area, so the end of the cast shadow will be more accurately visible. It is not necessary for a branch to be perfectly straight or stand strictly upright. Find the end of the shadow cast by the branch and mark it with a peg.

with a knife through it a line parallel to the flat side of the base and line West East. Then draw a perpendicular to the resulting line. That’s it, the configuration of the portable solar compass is completed, it is oriented along the sides of the horizon. First line based on compass West East, second North South. Graphic explanations are given on the right (enlarged) photo.

These sheaths are convenient in that they already have a suitable hole in the right place. Graphic explanations are given on the right, enlarged photo. And in the end, one important addition. If you need to use a portable solar compass for a long period of time, you should remember that it periodically needs to be checked and refined its settings. It is advisable to do this every three to four days (or even better every morning, before starting to move), according to the procedure described above. Otherwise, the solar compass will give large errors in its readings..
