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 metres.

3000m Depth Rating

Poseidon is rated for depths of up to 3000 metres, allowing it to be permanently mounted on deep diving subsea vehicles.

Multi-Constellation

Poseidon supports all of the current and future satellite navigation systems including GPS L1/L2, GLONASS G1/G2, GALILEO E1/E5, BeiDou B1/B2 and L-Band correction services.

High Performance

Poseidon features a cutting edge RF design, allowing it to achieve high positioning performance under difficult sea conditions. It is able to reject high levels of interference and multipath.

Compact Design

Poseidon is one of the smallest, depth rated GNSS antennas on the market, featuring an integrated, compact and lightweight design.
