Abstract
Ammonia masers are studied concerning their use as frequency standards. They oscillate on the J = K = 3 inversion line of N15H3 . Single beam masers allow the realization of a frequency standard with a stability of 2-3.10-11, and an accuracy of about 10-9. Experiments on double beam masers suggest that their use makes it possible to obtain a stability of the order of 10-12 and an accuracy better than 10-10.
