Laser for precise satellite navigation

Laser for precise satellite navigation.

 

 

Laser for accurate satellite navigation is designed for installation on the lunar locators. The accuracy of determining the coordinates of the object using the laser is reduced to 10 cm.

 


Description:

Laser for accurate satellite navigation is a pulsed laser. It is characterized by compact size, low beam divergence, a unique combination of short duration, high energy and energy stability, and high pulse repetition frequency, the resulting energy of the radiation does not vary from pulse to pulse.

The pulse duration of laser is 64 PS, output energy pulse or 253 MJ for “green” wavelengths, or 435 MJ for “infrared”, the repetition frequency of the pulse is 200 Hz.

The work of satellite navigation systems GPS and GLONASS is based on accurate measurement of distance between several satellites and the object.

To determine the location of the object, it is necessary to accurately know the coordinates of the satellites themselves. The last definition (coordinates of satellites) based on the measurement of the distance to the moon via laser ranging. In addition, the Moon affects the trajectory of the satellites, so these calculations need to be made constantly. Precision laser locators affects the accuracy of all measurements and calculations.

Laser for accurate satellite navigation is designed for installation on the lunar locators. The accuracy of determining the coordinates of the object using the laser is reduced to 10 cm.
