If a platform has just one Artemis antenna, how many vessels can it position using Artemis?

The correct response indicates that a platform with just one Artemis antenna is capable of positioning only one vessel at a time. Artemis antennas function as a part of the dynamic positioning (DP) system, providing essential positioning information through satellite signals. When equipped with a single antenna, the system can only communicate and receive data for one vessel, thus limiting its operational capacity.

This is due to the nature of satellite communications and the requirement for dedicated signal processing for accurate positioning. Although some advanced systems can handle multiple vessels, the limitation of a single Artemis antenna means that it cannot split its signal or processing capability among multiple vessels concurrently. Therefore, it has the capacity to focus on positioning just one vessel effectively at any given moment.
