Which of the following statements is correct concerning the principle behind the correction of one of the NAVSTAR/GPS satellite navigation system errors by the transmission of the signals on two frequencies (L1 and L2)?
A)The effect of receivers noise can be reduced due to the interference of both frequencies
B)The influence of shadowing on the GPS signals is proportional to the inverse of the carrier frequency squared
C)The path delay of the signals in the earth atmosphere is proportional to the inverse of the carrier frequency squared
D)The effect of signal reflections (multipath effect) can be reduced due to the interference of both frequencies
