The GP Sm provides se special satellite signals processed receiver. GPS receivers oy track exact location compute velocity time. positions en computed te dimensional views help fr GPS satellite signals. Space Segment Global Positioning System consists 27 Earth-orbiting GPS satellites. 24 operational 3 extra (in fails) GPS satellites. Te satellites round Earth 12 hours send radio signals fm space tt received GPS receiver.
The control Positioning Sm consists dt tracking stations tt located as world. Te monitoring stations help tracking signals fm GPS satellites tt continuously orbiting earth. Space Vehicles transmit microwave carrier signals. users Global Positioning System he GPS receivers convert satellite signals estimate actual position, velocity time. satellites required track te dimensional location time.
The operation sm based simple mathematical principle called Trilateration. Trilateration types i.e. 2-D Trilateration 3-D Trilateration. simple mathematical calculation GPS receiver sd things. Firstly location traced lt satellites place. Sd distance pe Space Vehicles. Units multiple receivers pick signals fm GPS satellites time. Te radio waves electromagnetic energy travels speed light.
· Overview
GPS specially Satellite Navigation Sm helps tracking exact location help satellites. Global Positioning System mainly funded controlled U.S Department Defense (DOD). initially designed operation U. S. military. today, te my civil users GPS as world. civil users allowed Standard Positioning Service wt charge restrictions.
