Saint Petersburg researchers created laser which may increase the precision of satellite navigation
The research assistants from Research and Investigation Center for Laser Physics at ITMO University which participates the project 5−100 have elaborated a powerful laser with short pulse duration for lunar laser locator. The locator is intended to measure the distance from Earth to the Moon with the precision of an order of several millimeters. Based on these measurements, one could introduce the corrections in the calculations of astronomical coordinates of the Moon to increase the precision of satellite navigation.
The measurements data are essential for satellite navigating systems as GPS and GLONASS are based on the precise determination of the distance between satellites and an object on the Earth surface.
