The Canopus transponder is the latest addition to iXblue's underwater positioning systems. Used as a reference seabed transponder or installed on tracked vehicles, it contributes to the best underwater positioning solution in terms of accuracy, functionalities and ease-of-use.
Canopus is an intelligent seabed transponder providing the most advanced LBL capabilities to iXblue positioning and navigation solutions.
Used either in sparse array mode, with Ramses transceiver and iXblue INS, or in full LBL mode depending on the requirements of the operation area, Canopus provides the highest positioning accuracy with the added advantage of reducing the number of transponders required.

iXblue has been chosen by the European Institute for Marine Studies (IUEM) to provide 8 Canopus LBL transponders for a major geodetic mission off the coast of Sicily. Deployed on the seabed, 2,500 meters below the surface, the Canopus transponders will measure the crustal deformation along the North-South Alfeo faults with a millimeter-scale resolution over the course of 4 years.
Nowadays, various positioning techniques are available for companies and institutes that need valuable navigation information to operate undersea. And while LBL usually remains the preferred solution for the highly accurate positioning of ROVs and AUVs, this method remains costly as it requires the use of many transponders to produce a single position. Operators are thus now looking for new ways that are more efficient, flexible and less costly to conduct their operations.
