Gaps, Issues, & Risks
We focus on every state of your program's radiation and electronics readiness. The Rad Team can identify missing data, known technical concerns, and potential mission impacts. We work with your team to mitigate and resolve all radiation reliability concerns.
Environmental Analysis
The Rad Team assesses the space radiation environment for your technology and mission profile, incorporating orbit, altitude, mission duration, and shielding to quantify exposure. This provides a mission aligned understanding of the radiation conditions driving design and risk.
Requirements Verification
Radiation requirements can quickly grow in complexity, increasing cost, schedule, and testing burden. The Rad Team ensures requirements are sound, properly scoped, and aligned with the mission environment, and develops targeted test plans for efficient, defensible compliance.
Shielding Optimization
We perform detailed shielding analysis and optimization tailored to the mission radiation environment, ensuring protection is applied where most effective and avoided where unnecessary. This approach minimizes mass while achieving required radiation tolerance for mission success.
BoM Analysis
The Rad Team offers a current status of your electronics designs with regards to radiation data by reviewing all publicly available data as well as our internal database to provide a disposition of radiation reliability for each individual IC and identify key gaps, associated risks, and recommended paths forward.
SEE Criticality Analysis
Single Event Effects Criticality Analysis (SEECA) is an assessment of single event effects within the context of system architecture identifies which effects drive mission risk and where mitigation is required. This prioritizes resources on the most impactful failure modes while supporting overall system reliability and mission success.
Assembly Evaluation
We assess board and assembly performance in the radiation environment by combining component behavior with implementation details to estimate availability and reliability. This identifies localized risks and validates design robustness at the assembly level.
Architecture Analysis
The Rad Team evaluates system architecture to identify failure paths, single points of failure, and opportunities for redundancy or mitigation. This ensures the overall design supports mission reliability under expected radiation conditions.
System Level Evaluation
The Rad Team evaluates the fully integrated system to quantify overall reliability and mission risk, accounting for interactions between subsystems, dependencies, and fault response. This provides a mission-level view of performance under radiation exposure.
Additional Services
ESD & Spacecraft Charging
Electrostatic discharges (ESD) and Spacecraft Charging are interconnected phenomena that can significantly impact spacecraft performance and safety. Our team leverages experts in this arena to ensure safety and prevention of operational failures in modern spacecraft.
Trade Studies
Targeted trade studies evaluate design options such as redundancy, shielding, and mission trajectories in the context of radiation risk. This enables informed decisions that balance performance, mass, cost, and reliability for the mission.
Program Support
Support through key program milestones such as PDR and CDR includes interpreting and applying NASA and customer requirements within a radiation context. This ensures designs, analyses, and test approaches are aligned for successful review and compliance.
