Poseidon is rated for depths of up to 3000 metres, allowing it to be permanently mounted on deep diving subsea vehicles.
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. L-Band correction reception allows reception of corrections from services such as Marinestar, Atlas and Veripos.
Poseidon is one of the smallest depth rated GNSS antennas on the market, featuring an integrated, compact and lightweight design. Its miniature connector takes up a very small footprint.
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.
Poseidon is ideal for use on ROVs to give them starting GPS position before diving.
Poseidon can be installed on an AUV which relies on inertial navigation while under water and returns to the surface to update its position with GPS periodically.
