DescriptionPoseidon is a subsea GNSS antenna designed for underwater vehicles which require the ability to obtain a GNSS fix when surfaced. The antenna is multi-frequency and suitable for marine vessels exposed to harsh conditions that are too extreme for a normal GPS antenna. It 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.
Features- 3000m Depth Rating: rated for depths of up to 3000 metres, allowing it to be permanently mounted on deep diving subsea vehicles.
- Multi-Constellation: supports GPS L1/L2/L5, GLONASS G1/G2/G3, GALILEO E1/E5, BeiDou B1/B2 and L-Band correction services.
- Supported SBAS Systems: WAAS, EGNOS, MSAS, GAGAN, QZSS.
- High-Performance: cutting edge RF design to achieve high positioning performance under difficult sea conditions; able to reject high levels of interference and multipath.
- Compact Design: one of the smallest depth-rated GNSS antennas on the market with an integrated, compact and lightweight design.
