Ramses is an acoustic synthetic baseline positioning system (ASBL) designed to make LBL and sparse-LBL subsea navigation simple.

Tightly coupled with Exail inertial navigation system (Phins, Rovins or Rovins Nano), it delivers extreme precision and robustness using a greatly reduced number of transponders compared to usual LBL systems.

Available in medium frequency version compatible with Gaps, Ramses is a key part of iXblue inertial-acoustic solutions for subsea positioning.
