MicroAutoBox II: Successful robustness tests for aerospace applications

January 11, 2016: Many development tasks in the field of aerospace engineering demand the applied hardware to be highly insensitive to height, temperature, and mechanical influences (vibration, impact), and to sources of electromagnetic disturbances. To confirm that dSPACE MicroAutoBox II is qualified for such scenarios, it was put through various tests in accordance with DO-160. The following table shows an overview of the tests in which MicroAutoBox II executed its running programs completely error-free.
