      High-precision location of space launch vehicles is a key component of the flight safety. The need for a very accurate location has gained the whole launch with the flight and re-entry stages being also critical in terms of safety. Thanks to the hybridization of GNSS and INS data, the accurate location can be fully defined inside the launch vehicle at low cost. This opens up to the setting of an autonomous system for location on-board the vehicle. Still, in order to ensure the reliability of such a system, many redundancies have to be set which implies to add equipment: autonomous power, processing, unique telemetry downlink... Adding this equipment challenging in an environment where the use of room and the adding of weight are very tightly monitored. This paper describes the techniques to settle a fully autonomous location system which answers to the needs for an accurate, strongly reliable location while being non-intrusive, cost-effective and easily integrated in any launch vehicle.
    • Hybridization of wireless technologies for the aerospace instrumentation

      Whatever the flight test or space launch vehicle, instrumentation presents strong intrusiveness due to cabling. The industry is resolutely looking for a transition toward wireless architectures for elimination of cabling while not compromising data integrity and network performances. The ideal wireless solution is a single technology that could encompass all the needs. But there is a wide variety of use cases and associated requirements: data throughput, synchronization accuracy, power consumption, robustness of the link, frequency regulation constraints. Today, no technology is able to cover all these needs. However, multiple technologies show specific characteristics that are optimized for some particular use cases. Hybridization of multiple wireless technologies in a complex system is the right solution to address specific applications with the optimal wireless instrumentation solution and no concession on performance.
