Navigational instrument or tool such as a sextant or astrolabe is used to measure the angle between a celestial body (sun or stars) and the horizon. This information helps determine the ship's position on a map by calculating latitude and longitude coordinates.
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 Hertzsprung-Russell diagram is a scatter plot of stars showing their luminosity (brightness) versus temperature (color). It helps astronomers classify stars based on their size, age, and evolutionary stage. The diagram is crucial for understanding the life cycle of stars and predicting their future evolution.

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.
At first they sailed around coastlines, then worked ot how to use the polar star to keep their bearings when away from land.
The plot area is the rectangular area formed by the axes. The chart area is bigger and includes the title, the axes labels and values and the key (in its default positions).
