No. They're strictly measurements of angles on the Earth's surface. They
have no connection with any current solar characteristic, any more than
angles on the surface of a Basketball have.
latitude and longitude
The key lines are latitude and longitude. These are based on specific points. The equator is the latitude around the center of the earth. Longitude is measured from the Prime Meridian, which goes through the Greenwich Observatory in England.The Tropics and the Arctic/Antarctic Circle are also key.
Longitude proved more difficult to determine because longitude was based in the concept of time, making clocks an important variable in navigation. The time and distance in addition to the use of the sextant for latitude proved more difficult than measuring the latitude.
Time Zones are based on lines of Longitude - with detours to avoid land.
The Greek invented latitude and longitude. Someone devised a concept of using a reference system based on the shape of the Earth, with the coordinates (latitude, longitude) expressed as degrees. In the 3rd century BC Erathosthenes proposed a system of latitude and longitude for a map. The following century (2nd century BC) Hipparchus was the first to use the above system to uniquely specify certain places on th Earth.
what improved the ability to determine latitude and longitude based on the stars
latitude and longitude
latitude longitude
Global positional systems (GPS) work by triangulating your position based upon finding your longitude and latitude. A device will find longitude and latitude and the GPS will read that and translate it into maps.
That is called the coordinates of the place.

There are many things which are depend on coordinate geometry, for example when a person or government wants to find where a place is situated, or the location of a person, longitude and latitude coordinates can be used to find them. The whole globe is based on longitude and latitude - where the lines of longitude and latitude meet is a coordinate.For example, it is possible to find the longitude and latitude of a place and then use those coordinates to find the place on a map. The location could also be put into a sat-nav device which uses its current longitude and latitude coordinates to work out a route to the destination - all in little steps between different coordinates.
Any measurement used in navigation, whether longitude or latitude, is based on the 360 degrees of a full circle. The Prime Meridian is a line of longitude that passes between the poles, passing through the Greenwich Observatory in London, and is zero. So, any measurements West or East of this line, will be in degrees (based on 360) and using minutes and seconds for finer location.
The geographical coordinates of India are:Latitude of India: 20º00´ North of the EquatorLongitude of India: 77º00´ East of Greenwich82.5 is the central meridian (called centre longitude)longitudinal extent 68º7'E to 97º25'Elatitudinal extent 8º4'N to 37º6'N
