Inertial navigation is one of the core areas of expertise developed by Safran Electronics & Defense over more than 70 years, particularly in the military arena. Safran is one of the sole players in the sector with a perfect mastery of all the associated technologies: gyroscopes, gyrometers, accelerometers, integrated GPS receivers, electronics (ASICs), navigation data processing, etc. Safran has concentrated their expertise into two inertial navigation systems (SIGMA 95N and GADIRS), to best meet your operational needs. They combine great reliability, high precision (short- and long-term) and extreme robustness.
GADIRS (GPS Air Data & Inertial Reference System) is a hybrid triplex navigation system with a high level of security and integrity. Designed to meet the future needs of military transport aircraft, it can be used to carry out all tactical or strategic military air transport missions in hostile environments.
Developed and produced by Safran, the GADIRS system is based on three hybrid INSs. It contains anti-jam radionavigation functions and uses the latest technologies, such as GPS SAASM. Controlled Reception Pattern Antenna ensures a high level of protection from accidental or intentional electromagnetic interference. Selected by Airbus for the A400M, the GADIRS is also certified to civilian standards.
