Which of the following is false about Direct ranging in Loran-C?(a) Us

1.	Which of the following is false about Direct ranging in Loran-C?(a) Uses Rho-Rho mode(b) Requires minimum 2 stations(c) Cost efficient(d) High stable user frequency standardThe question was asked during an online exam.Enquiry is from Hyperbolic Radio Systems in section Terrestrial Radio Navigation System of Avionics
Answer» Correct choice is (c) Cost efficient The explanation is: Direct ranging Rho-Rho mode requires a minimum of TWO stations, a HIGHLY STABLE user frequency standard and precise knowledge of the time of transmission of the signal. The use of this mode is limited by the high cost of stable frequency standard.
