Efficient Environmental Test Campaign Planning for EyasSat Space Mission Validation

This document outlines the test campaign planning and execution for the EyasSat space mission, emphasizing the design verification and validation processes. Critical models include the Launch Vehicle Interface, which ensures compatibility with the launch vehicle, and the Acoustic Simulation Model, which assesses the satellite’s resilience to launch-induced acoustic conditions. The strategy involves concurrent testing of all five EyasSat units to minimize logistics costs and scheduling risks. The timeline accounts for potential delays, utilizing facilities at Goddard, Kennedy, and Marshall Space Flight Centers for comprehensive verification.

  1. Environmental Test Campaign Planning Exercise Brent Eversole SYS 633 – Space Mission Design, Verification & Validation

  2. Project Test Philosophy • Model Types • Launch Vehicle Interface Model – Used to check the fit between the EyasSat and the Launch Vehicle • Acoustic Simulation Model – Used to verify that the satellite will survive and operate after the acoustic environment during launch. • Risk Approach • All 5 EyasSat’s will undergo each type of testing at the same time. This will keep logistic costs down but also if one satellite is held up, all 5 are then held up creating a schedule slip. • Dates for timeline have margin built in to allow for any delays or deviations from the schedule, which will help mitigate risk.
