摘要

High performance Tactical UAVs offer a concentrate of hybrid inertial technology. These are used in every flight phase. They play a first rank role in its fulfillment: flight path accuracy, image stabilization, geo-localization of objects. But these techniques are also at the heart of flight security. A tactical UAV like SPERWER carries three different pieces of inertial equipment, which are independent, organized within a common system and hybridized with all other flight sensors : Magnetic field sensor, air data system, GPS. The performance level of the navigation sensors went through a fine analysis in order to determine the best compromise mass/performance. The aim is to respect tough perf. criteria during missions (image quality, localisation) while keeping within mass , volume and power consumption criteria compatible with a 300 Kg aircraft. This is why the chosen sensors are of a lower class w.r.t. those found on combat aircraft, and do not feature same redundancy. Instead, hybridization level and differential GPS techniques compensate for this deficit and insure the desired performance. Besides, use of inertia associated to satellite navigation permits to fulfill the mission even into degraded environment. Today, relying only on GPS would present a danger linked to permanence of the service. GPS jamming techniques are progressing and become usable by numerous countries. It has become essential for a tactical UAV to be able to continue its mission in case of a loss of the GPS service. Inertial techniques installed on board SPERWER enable this, while offering a correct level of redundancy in case of failure. This is while guidanceavigation system on SPERWER was subject to a Certification according to the European civilian standard JAR-VLA. This certification is a world premiere for tactical UAVs. It is also a major innovation for the VLA category (aircraft's under 750 kg MTOW) through use of advanced hybridized inertial techniques, unknown so far to this type of aircraft.
