The SEXTANT. This instrument will give the latitude of a ship. However, because of solar movements a CLOCK(Time piece) is needed to determine the longitude(meridian). So the two inventions are ; - The Sextant, and the Clock .
a star diagram is a circle on which we plot the location of stars the circle represents the sky above and it is divided into 4 quadrants while knowing the northerly direction we plot the stars with respect to its location from true north and we tabulate its declination in a separate column since location of stars for a particular time from a particular geographical position is predictable so we match it and obtain own position in terms of latitude and longitude
The main sequence phase means that, if you plot an H-R (Hertzsprung-Russel) diagram, it is in the so-called "main sequence", the area in the graph where you find the majority of stars. Those are the stars that currently fuse hydrogen into helium.

The captain and Officer of the watch (OOW) have a range of tools to help them plot another vessels position. The most common way is to find and select the other vessel (target) on a radar screen, this gives a graphical representation of where the target is in relation to own ship.(provided radar is set up correctly) Another is to take visual bearing of the target ship and plot it onto an appropriate nautical chart.

Sing the happiest song you know to help you keep your bearings in unfamiliar terrain.
Use a compass to take 3 bearings to known objects on the map and plot the reverse bearings from these on the map. Where the lines cross is your exact (to the scale of the map) location.Use a GPS and plot your position using the map coordinates.
At first they sailed around coastlines, then worked ot how to use the polar star to keep their bearings when away from land.
