Sažetak
Ease of use satellite communications technology onboard merchant ships rejects HF communications systems. It is inappropriate routine by means of maritime safety since GMDSS satellite communications systems rely on INMARSAT exclusively. Although INMARSAT was originally founded originally founded in 1979 as not-for-profit international organization, it is since 1999 privately owned company. HF communicating does not require radio relay link but highly depends on very variable ionospheric condition. Precise MUF assignation, crucial for HF link establishment is not possible without experienced operator. GMDSS equipment does not include HF ALE modem and this paper proposes it as supplement appliance to existing technical solution.
