When you are using a compass you are navigating to a certain point. So it could be navigation.
The mariners compass was invented by using LORIS , a wild animal for navigation
Navigation out of sight of land using the Polar Star.
All GPS navigation systems are up for debate as to which one is easier. Garmin is a more popular brand; you may have an easier time using a Garmin GPS.
There was no real technological help in 1490's. How they did explore is they would examine the stars, sun and landmasses to figure out which way they were heading. The first real piece of technology that made exploring at lot easier was the compass created in 221-230 BC by the Chinese but the first recording of someone using the compass to explore was in 1371 by a Chinese explorer named Zheng He.
A device that is used to determine orientation on a map is a compass rose. The type of map projection that is most helpful in the navigation of ships is a Mercator map.
The compass is important because with out it we would get lost. It helps ships navigate their way to land, and people that get lost in the woods back to their camp. To sum it up a compass helps you find you way, get your bearings, and navigate.

It is called an astrolabe.
A compass can work at all times. You can't see stars during the day. Even at night, there needs to be at least fairly clear skies to enable you to see stars and work out your direction. A compass can be easier to use. You need a knowledge of the stars, which you don't need with a compass. A compass should work anywhere. The night sky looks different on different parts of the planet which can be confusing.
There are compass systems using MEMS. MEMS means micro electromechanical systems. The MEMS compass system uses a vibrating structure gyroscope to operate. Most MEMS inertial navigation systems have integrated GPS. The very sophisticated ones are independent to prevent jamming, they use computers and an accelerometer as well as a MEMS gyroscope to operate.
