Engineering support for your subsystems and mission.

Systems engineering and architecture

• Subsystem requirements and architecture aligned with the customer mission concept.
• Requirements allocation, interface control and verification planning.
• Subsystem trade studies, equipment selection and make-or-buy assessment.
• Mass, power, energy, data, pointing and thermal budgets.
• Reliability assessment, fault containment and FDIR architecture.
• Technical risk assessment, design margins and configuration control.
• Preliminary and critical design reviews, supplier interfaces and acceptance evidence.

Engineering outputs: requirements baseline, architecture definition, trade-study reports, budgets, interface documents and verification matrix.

Orbital analysis and mission design

• Orbit selection and constellation geometry.
• Ground access, coverage, revisit and contact opportunities.
• Eclipse duration, Sun geometry and illumination constraints.
• Payload viewing geometry and attitude-related observation limits.
• Propagation and sensitivity analysis matched to the engineering question.
• Drag, lifetime and orbit-decay assessment with stated environmental assumptions.
• Relative motion and phasing studies for constellation deployment and maintenance.
• Link geometry and Doppler profiles for communications design.

Engineering outputs: scenario definitions, model assumptions, orbit and access results, coverage plots and design recommendations. Catalog propagation, analytical perturbation models and numerical integration are selected for their intended use rather than treated as interchangeable tools.

Maneuver analysis

• Delta-v, propellant and total-impulse budgets.
• Orbit raising, lowering, phasing and drag-compensation strategies.
• Finite-duration and low-thrust maneuver assessment.
• Power, energy, thermal and attitude constraints during firing.
• Thrust alignment, pointing error and maneuver-execution sensitivity.
• End-of-mission maneuver planning with explicit assumptions.

Engineering outputs: maneuver trade studies, delta-v and impulse budgets, analytical firing scenarios and stated model assumptions.

Mission planning and operational readiness

• Payload and communication schedules linked to spacecraft resource limits.
• Time-tagged command sequences and operating-mode transitions.
• Ground-contact planning and telemetry/downlink priorities.
• Safe-mode, contingency and recovery procedures.
• Mission databases, command dictionaries and telemetry-limit definitions.
• Operator training, rehearsals and end-to-end simulations.
• Launch and early-orbit readiness reviews.

Engineering outputs: operating concept, mission timelines, procedure set, constraints register and rehearsal results.

Mechanical, thermal and test engineering.

We design subsystem structures, electronic enclosures and integration hardware for CubeSats and SmallSats. Analysis, manufacturing engineering and verification support the hardware from concept through acceptance.

Assembly, integration and verification

• AIT sequence, interface checks and integration-readiness planning.
• FlatSat benches, harness breakouts and subsystem simulators.
• Functional, performance and fault-recovery tests.
• Environmental campaign planning and execution support.
• Nonconformance investigation, corrective actions and retest planning.
• Configuration checks and requirement-by-requirement evidence closure.

Engineering outputs: integration plan, test procedures, test equipment, anomaly records and verification reports. Mechanical, thermal and test engineering is also available as a dedicated work package.

Commissioning and in-orbit support

• First-contact and subsystem activation procedures.
• Telemetry interpretation and expected-versus-observed behavior review.
• Power, thermal, communication and ADCS performance assessment.
• Payload commissioning support.
• Anomaly diagnosis, recovery-option assessment and procedure updates.
• Transition planning from commissioning to routine operations.

Engineering outputs: commissioning plan, telemetry assessments, anomaly analyses and updated operating procedures. Work is coordinated with the spacecraft operator and its command-authorization process.

Technical reviews and team support

• Independent system and subsystem design reviews.
• Supplier technical evaluation and interface assessment.
• Root-cause investigation and test strategy development.
• Embedded electronics, software and mission-engineering support.
• Technical documentation, knowledge transfer and engineering training.
