The T-7A is the new jet trainer aircraft for the United States Air Force. The prototype T-7A test aircraft were flown based out of a contractor test facility 2,800 km away from the Air Force test team. The combined government and contractor test team established distributed test operations that enabled engineers to monitor real-time flight test missions with telemetered data and communication in control rooms at both the contractor location and the remote government location. This paper describes the setup and capabilities of the network connection; the events used to establish distributed test operations; the concept of operations across multiple organizations; technical, organizational, and contractual challenges encountered and lessons learned; and planned future growth of this capability.

: More and more players on the market try to get in the game of sophisticated helicopter manufacturers. There are several interesting industries that helicopters are needed for. The famous ones like military and air transport for air lifting are now extended by new mobility concepts like the electrical urban air mobility. But all have the same challenges with innovations on drives and transmission leading to many newly designed critical rotating components where temperature, strain, force or acceleration measurements for durability and operational strength need to be exercised. In this paper, MANNER shortly sums up the challenges that come with the engineering and development of a high-quality, high accuracy telemetry measurement system. A system withstanding all environmental constraints and mechanical challenges but being flexible for the customer as well as for the different measurement tasks in every mean. Sample timestamping and data structure need to be taken into account for accurate measurements in such big measurement tasks. The request for IENA and Precision time protocol (PTP V2) has been realized as one way to go with the new generation of telemetry systems. The aim of this paper is to provide the reader a good insight on the challenges of telemetry systems on helicopters and the solutions that have been found to realize a highly reliable, highly accurate yet very flexible measurement system that now is an answer to all measuring tasks on a helicopter.

: A new method for calibration, validation aiming at certification of GNSS receivers used in the automotive industry addressing the levels 3 and 4 of automation under real world conditions is presented. The method uses simultaneously acquired high-resolution aerial image data, from a helicopter, which is precisely georeferenced with Ground Control Points. The method provides a reference trajectory for vehicles in GNSS critical areas, e.g., GNSS-denied type environments. The images obtained contain the vehicle’s roof with the signalized GNSS receiver antenna. Together with a precise height model of the road surface, the absolute position of the GNSS receiver in world coordinates can be derived from the position in the image. The main results of a test campaign, performed in July 2021, using the method are presented. It was investigated how the quality of the GNSS sensors is influenced by the environment (Rural, Highway and Urban) and what added value the method provides. The method proved to be resilient and robust to situations where the GNSS position accuracy degrades, even when RTK is used, as local effects do not impact the new method. The method provides high-precision reference trajectories facilitating calibration, validation, and conformity testing. In this contribution the focus will be set on the validation and testing process leading to certification.
