17/12/2016 Introduction Poseidon is a subsea GNSS antenna that is designed for use on underwater vehicles that require the ability to obtain a GNSS fix when surfaced. The antenna is also suitable for marine vessels that are exposed to harsh conditions that are too extreme for a normal GPS antenna. The antenna is capable of tracking GPS L1/L2/L5, GLONASS G1/G2/G3, BeiDou B1/B2, Galileo E1/E5 plus L- band.

Table 5: Coaxial cable specifications Coaxial Connector Poseidon's coaxial connector is designed to be compact with a diameter of only 15 mm. It has a maximum mated pressure rating of 600 bar allowing it to be used at depths of up to 3000 metres.
1. Poseidon should be mounted in a position that allows it to have a clear and unobstructed view of the sky. 2. Poseidon should be mounted in a position that is above the water line when the vehicle is surfaced.
17/12/2016 Connector Maintenance Care should be taken not to over tighten the Poseidon connector. Tools should not be used when tightening the connector, it should only be tightened by hand. The coaxial connectors are only pressure rated when they are mated. When the connectors are unmated, be careful not to allow dirt, water or any other foreign matter to get into the connector.
