Developing Safety-critical Software Requirements for Commercial Reusable Launch Vehicles

A number of inventors and entrepreneurs are currently attempting to develop and commercially operate reusable launch vehicles to carry voluntary participants into space. To reduce the risk to the public in the operation of these vehicles, a launch vehicle operator typically performs analyses to identify safety measures and develop safety requirements. The focus of these safety efforts has histo...

First Commercial Experiment

For many years, non-target detection experiments have been simulated by using AND/OR bridges or gross delay faults as surrogates. For example, the defective part level can be estimated based upon surrogate detection when test patterns target stuck-at faults in the circuit. For the rst time, test pattern generation techniques that attempt to maximize non-target defect detection have been used to...

Smos Mission Salinity Retrieval: Post-launch First Assessment

In this paper, first preliminary results obtained during the commissioning phase of the Soil Moisture and Ocean Salinity (SMOS) mission are described, devoting special attention to the characterization of the systematic errors found in the measurements and the corresponding impact in the retrieved geophysical product. The identified issues and objectives to consolidate and improve the processin...
