What Are
Satellite Structures?
Satellite structures are the mechanical framework that holds the spacecraft bus, payload, electronics, power system, sensors and propulsion hardware in alignment through launch and orbital operation.
For most programs, the core requirement is simple to state but hard to execute: reduce mass while preserving stiffness, interface accuracy, thermal stability, clean material evidence and repeatable documentation.

Satellite Structures FAQ
Short answers to the questions teams usually ask before sending satellite structure drawings.
6061-T6 is common for bus frames, panels and secondary fittings where machinability and cost matter. 7075-T6 is selected when higher strength can reduce section size and mass. The final choice depends on loads, stiffness, finish and program material rules.
Satellite structures must combine low mass, high stiffness, vacuum-compatible materials, thermal cycling stability, launch vibration survival and long-term configuration records. They often need more documentation than ordinary machined aerospace hardware.
Yes. CNCPioneer can support flat-panel satellite structures, repeated mounting hardware, production fixtures and batch inspection plans for constellation-style programs after DFM and first article approval.
Reaction wheel mounts, star tracker brackets, gyro supports and payload instrument interfaces are especially sensitive because small alignment errors can become pointing or imaging errors at system level.
Programs commonly reference ASTM E595 limits for TML and CVCM. Metals are usually straightforward after proper cleaning, while polymers, coatings, adhesives and lubricants need grade-specific evidence.
Simple aluminum structure parts can often be prototyped in 5-10 business days depending on finish and documentation. Titanium, Invar, deep pockets, complex frames or full FAIR packages add time.
The meaningful comparison is capability and evidence: AS9100D scope, machining accuracy, CMM reports, material traceability, surface treatment control and FAIR documentation. CNCPioneer combines those controls with China-based machining economics.
