Technology multinational GMV has signed a contract with Spanish corporation Navantia for the development and supply of the SENDA navigation system for the future F-110 frigates, which will replace the current SANTA MARIA class frigates from 2026. This contract shows the trust already placed in GMV by the Spanish MoD on the strength of the fine work carried out in the development of a system prototype within the F-110 definition phase.

These vessels represent a technological leap forward in platform and combat systems, incorporating Industry 4.0 technologies into their design to improve system management. The SENDA navigation system, for its part, is GMVs’ advanced naval navigation and timing solution which provides positioning, speed and timing data in various formats. It also incorporates multi-constellation (GPS, Galileo) satellite navigation technology compatible with both civil and military signals, plus DGNSS corrections and includes state-of-the-art algorithms to provide robust navigation in contested GNSS scenarios.

There is also a timing server that generates highly precise and stable timing signals, allowing the ship’s systems to synchronise with GPS time while the system guarantees timing reference stability and negligible drift, even during prolonged periods of GPS downtime. As a totally redundant system, SENDA has two complete functional subsystems working in active-active configuration, together with redundant GNSS signal distribution. Both systems, monitored in real time, exchange information to provide the overall system with the best possible solution.

The complete SENDA system, taken together with GMV’s range of defense products, makes GMV a national navigation-system benchmark, with tried and tested experience in the aeronautics, land and naval sectors in platforms like the unmanned aircraft ATLANTE, the 8×8 DRAGON vehicle and now the F-110 frigates.
