If you are tracking the POR satellite and want to communicate by voice using LES Santa Paula with another ship tracking the AOR-E satellite, what is the correct procedure?

When communicating via satellite in a GMDSS context, it is essential to choose the correct Land Earth Station (LES) based on the satellites you are using. In this scenario, you are tracking the POR (Pacific Ocean Region) satellite while communicating with another vessel that is utilizing the AOR-E (Atlantic Ocean Region-East) satellite.

Selecting the appropriate LES is vital because each LES corresponds to specific geographical areas and traffic management of satellite communications. The correct procedure involves using the unique identifier for the LES that ties directly to the POR satellite.

In this case, selecting LES: 001# is appropriate since it corresponds to the satellite coverage for the region you wish to operate in. Subsequently dialing the specific number, 00870323972310#, completes the satellite call to the other vessel. The number follows a specific dialing format that ensures proper routing through the necessary stages of satellite communication.

Each number varies by region, satellite, and specific LES capabilities, making accuracy in selection crucial for successful communication. Therefore, Option A represents the correct sequence to establish voice communication between two vessels utilizing different satellites effectively.
