Asset Management in Space Flight Hardware: Maximising the Value of Every Engineering Unit

A conventional spacecraft development programme may call for an Engineering Model (EM), Qualification Model (QM), Flight Model (FM), and sometimes one or more flight spares. For a complex spacecraft, this can mean that a customer pays for several almost-identical pieces of hardware before a single unit ever reaches orbit.

There are good engineering reasons for this approach. Engineering models provide a platform for software and interface development. Qualification models demonstrate that the design can survive the required environmental conditions. Flight models are manufactured and verified for the actual mission. However, there is another question that should be asked much earlier:

Can the same hardware create value at more than one stage of the programme—or even become a different product altogether? This is the foundation of effective asset management in space flight hardware. At CAVU Aerospace, we believe the objective should not simply be to minimise the number of units manufactured. The objective should be to maximise the engineering value generated by every unit the customer pays for.

The traditional EM–QM–FM approach

A simplified conventional development flow might look like:

Engineering Model → Qualification Model → Flight Model → Flight Spare

Each unit has a specific role. The Engineering Model is typically used for software development; firmware development; interface testing; spacecraft integration; performance testing & customer training. The Qualification Model is normally used to demonstrate that the design can withstand the environmental conditions expected during the mission, potentially including vibration, shock, thermal-vacuum and other mission-specific tests.

The Flight Model is then manufactured and subjected to the appropriate acceptance and verification programme before entering service. This approach is technically sound. But it can also create significant duplication.

A customer could potentially purchase 1 × EM, 1 × QM, 2 × FM, 1 × flight spare

That is five sophisticated pieces of hardware, while only two may ultimately perform the mission. The additional hardware may be entirely justified. The problem is when the hardware lifecycle is not considered from the beginning. The question should therefore change from: “How many models do we need?” to: “What is the most valuable lifecycle for each asset?”

The greatest opportunity for cost optimisation often exists before procurement begins. This changes the philosophy from hardware procurement to hardware lifecycle management.

There are actually several levels of hardware reuse.

• Level 1 — Reuse the physical unit
• Level 2 — Reuse the unit as a ground asset
• Level 3 — Reuse the hardware platform
• Level 4 — Reuse the design heritage

The same PCB and core electronics are used in different product configurations. For example:

• Common OBC Base Board → OBC-Hyper-Polar
• Common OBC Base Board → Typhoon-Edge
• Common OBC Base Board → Other mission-specific configurations

The peripheral architecture changes, but the core computing platform remains substantially common. Even when a new physical unit must be manufactured, the engineering investment is reused. This can be extremely valuable because the most expensive part of a space computer is not necessarily the physical PCB—it is the engineering knowledge behind it.

CAVU’s approach: one OBC platform, multiple products

A good example of this philosophy is CAVU Aerospace’s approach to its OBC platforms. The OBC-Hyper-Polar, Typhoon-Edge and other configurations can share a common OBC base-board architecture while being adapted for different mission requirements through their peripheral and system-level configurations. Instead of designing a completely new computer for every application, the core OBC platform can be treated as a reusable engineering asset.

The customer therefore benefits from the development work being distributed across multiple configurations. A simplified architecture can be viewed as:

Common OBC Base Board

↓

Different peripheral / interface architecture

↓

Different product configuration

↓

Different spacecraft application

For example:

• OBC Base Board + mission-specific peripherals → OBC-Hyper-Polar
• OBC Base Board + high-performance edge-computing architecture → Typhoon-Edge
• OBC Base Board + other mission-specific interfaces → other CAVU configurations

This approach means that the engineering work invested in the base computer does not belong to only one product. It becomes a platform asset. This is particularly powerful during development. Imagine that the first application requires a particular OBC configuration. The customer funds engineering development, PCB design, firmware, BSP development, testing and integration. Once that work is complete, it would be inefficient to treat all of that engineering effort as belonging exclusively to the first product. Instead, the same base architecture can become the starting point for another configuration.

The second product may require additional interfaces; networking; mechanical packaging; additional FPGA functionality; high-performance AI processing or different peripheral boards. But the core OBC can remain common. This means that the second configuration does not necessarily begin at zero engineering maturity. It begins with an existing platform.
