https://metrotec.ee/wp-content/uploads/2017/01/avapilt.jpg19201276Modern GPS navigation has been in use but a couple of decades, yet the art of locating one's position has a history that long predates the advent of the satellites. Nowadays, even among professional mariners, there are those that no longer understand how to navigate without modern instruments. However, even in this age of GPS-capable smartphones and navigation devices, it may come in handy to remember what to do if you are unable to obtain a signal from the sky or the battery of your pocket device has died.
