Question

Which of the following advantages does the differential Loran-C provide?

(a) Stable user frequency

(b) No seasonal errors

(c) Cost efficient

(d) Very high range of 500miles

I got this question in an online quiz.

I need to ask this question from Hyperbolic Radio Systems topic in section Terrestrial Radio Navigation System of Avionics

Answer 1

Correct choice is (b) No seasonal errors

For explanation I would say: The corrections using differential Loran-C are generally valid for the co-relation distance of approximately 100 miles from the reference station. Real time co-relations remove both seasonal and diurnal errors can be broadcast.
