The most modern day equivalent is a GPS although the device that most closely resembles an astrolabe in purpose and design is the sextant. The sextant measures the height of the sun or stars above the horizon. By taking several measurements about noon or with an accurate time keeper at other times, the latitude of the observer can be found, placing the observer somewhere on that line about the earth. With an accurate time piece, the longitude (distance east or west of Greenwich, England) can be found and the two determine where on Earth.the person is located.
Before accurate time pieces, open ocean sailing consisted of sailing north or south to a given latitude then sailing east or west to strike the destination.

Mike makes an interesting point but people today actually doing navigation do not use sextants. Astrolabes were mainly used for navigation, determining longitude, local time ... go with GPS today, which does all of those things.
