Uliss inertial navigation and nav/attack systems Uliss modular systems all employ high-accuracy inertial components consisting of two dynamically tuned gyros and three dry accelerometers, a microprocessor-controlled computer working at 1 Mops with EPROM memory and highly integrated and hybrid circuits. As an option, Uliss can be equipped with an embedded GPS receiver for high-performance INS/GPS coupling and a higher-performance RISC processor using Ada language. Uliss systems fall into two categories, in both of which the main inertial navigation unit is contained within a {3/4} ATR short case. In the first category are navigation versions with a position accuracy of better than 1 n mile/h. In the second category the navigation function is combined with the computation necessary for weapon delivery. Alignment time is 90 seconds for stored heading and 5 to 10 minutes for self-contained gyrocompassing. Standard interfaces permit the systems to be linked to other equipment via MIL-STD-1553B databusses or ARINC serial data lines. A failure detection system can detect faults at module level with 93 per cent confidence, isolate them and signal their presence on a magnetic annunciator without external test equipment. More than 80 per cent of the components and subassemblies are common to all members of the Uliss family, the principal differences being in specific interfaces and computation functions. In all, 1,600 Uliss units are in operation on 25 different types of aircraft. Uliss 92 Inertial Nav/Attack System The Uliss 92 combines in a single box all the functions of an inertial navigation and fire-control system. It is based on Ada programming and comprises three units: UNA 92 inertial/attack box, PCN 92 control/display unit and PSM 92 mode selector. SPECIFICATIONS :
