Global navigation satellite system gnss/gps what the minimum number of gnss/gps satellites required to obtain an accurate 2d position fix Question Section 5: Navigation 68 Answer 8
Global navigation satellite system gnss/gps what are effects if any of shadowing parts of aircraft e g airborne camera on reception of signals from gnss/gps satellites It may prevent reception of signals, it has no influence because high frequency signals are unaffected, the signals will be distorted, however error can be corrected using an algorithm information from unaffected signals, it causes multipath propagation. Question Section 5: Navigation 68 Answer 9
Radio theory when raising frequency of an electromagnetic wave the Wavelength decreases, wavelength increases, wavelength remains same, wavelength amplitude increases. Question Section 5: Navigation 68 Answer 10
Radio theory with regard to radio waves propagation a cycle defined as A complete series of values of a periodical process, a number of oscillation per second, the length of pulse, the distance covered a radio wave in one second. Question Section 5: Navigation 68 Answer 11
Radio theory how the unit 'hertz' hz defined The number of electromagnetic oscillations per second, duration of an oscillation, the distance covered a radio wave in one second, the number of electromagnetic oscillations per minute. Question Section 5: Navigation 68 Answer 12
Radio theory the 'amplitude' of an electromagnetic wave defined as Maximum deflection in an oscillation or wave, physical length of an oscillation, number of cycles occurring in one second in a radio wave expressed in hertz (hz), wavelength. Question Section 5: Navigation 68 Answer 13
Radio theory diffraction the process which Radio wave travel over around obstacles, a space wave penetrates ionosphere, a ground wave attenuated over rough ground, a direct wave bent around form of earth. Question Section 5: Navigation 68 Answer 14
Radio theory frequency defined as Number of cycles occurring in one second in a radio wave expressed in hertz (hz), minimum number of cycles occurring in one minute in a radio wave expressed in hertz (hz), maximum deflection in a radio wave expressed in hertz (hz), length of a radio wave expressed as an angle. Question Section 5: Navigation 68 Answer 15
Radio theory wavelength defined as Physical distance travelled a radio wave during one cycle of transmission, maximum variation of an oscillation, distance travelled a radio wave in one second, number of oscillations per second.
