Ramses

Long baseline MF and LF positioning systems

Next-generation long baseline medium frequency and low frequency positioning systems

20-30 kHz MF band - 8-17,5 kHz LF band

Up to 6 000 m depth rating

Ramses is an acoustic synthetic baseline positioning system with self-contained computing, for simple real-time sparse array subsea navigation. Tightly coupled with iXblue inertial navigation system (INS), it delivers extreme precision and robustness in challenging acoustic operational environment. Available in MF and LF versions (medium frequency for most applications and low frequency for ultra-long range applications), Ramses is part of iXblue inertial-acoustic solutions for underwater positioning and navigation thanks to the connection with iXblue GAPS or POSIDONIA ultra-short baseline (USBL) positioning systems.
