VLF PULSE TIMING: LIMITATIONS AND POTENTIAL AS A COMPANION TO OMEGA

Abstract:	The potential accureacy of VLF pulse (envelope) timing is severely limited by vagaries of the propagation medium and atmospheric noise due to spherics. These limitations are discussed in depth. The conclusion is that VLF pulse-timing accuracy corresponding to about 5 nmi. should be possible over very long ranges up to 5000 n.mi. A hypothetical system employing pulse transmitters co-located at the Omega sites is explored. It is proposed that such a pulse system and the present phase-only Omega system could serve to complement each other as a coarse-fine system.
