Poseidon

Poseidon is a subsea GNSS antenna designed for underwater vehicles which require the ability to obtain a GNSS fix when surfaced.

Poseidon is a multi-frequency 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 receiving L-Band corrections to provide accurate positioning at sea. The antenna is lightweight, compact, corrosion-resistant, and able to withstand depths of up to 3000 meters.
