The Physics behind GPS

  1. Mar 4, 2009 #1
    Hello i need help regarding GPS devices and the physics that goes into them.
    This may include, how the signal travels from source to GPS. Refractional waves and atmosphere interference.

    The process that goes into GPS devices in finding ur position. (Physics Based)

    thank you =]

    Geosynchronous orbit
    Triangulation

    Finding Position:
    time transfer - to correct for relativistic effects
    Geometric trilateration

    Here's a short video on geometric trilateration:
