StarSpec develops precision attitude-control components including SASC star cameras, cogless reaction wheels and ADCS electronics. Supplier specifications distinguish sub-arcsecond full-lost attitude accuracy at 10 Hz from 0.23 arcsecond differential precision at 60 Hz; controller stabilization depends on paired camera and wheel hardware. NASA credits StarSpec with the EXCITE balloon gondola, while CSA funds a separate 12 U InspireSAT ADCS development programme. Balloon instrument heritage does not establish orbital constellation readiness.
Technical detail
Core features
SASC full-lost accuracy below 1 arcsecond at 10 Hz
SASC differential precision 0.23 arcsecond at 60 Hz
ADCS controller 10–100 Hz bandwidth with camera/wheel feedback
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Balloon-platform heritage is documented by NASA, including the 2024 EXCITE test flight. CSA InspireSAT MVP support runs through December 2026; completed orbital-system qualification was not recovered.
Commercial availability
Components and integration services are offered directly. Confirm payload inertia, pointing budget, wheel configuration, radiation/thermal test scope and orbit-specific qualification before applying published accuracy figures.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
An integrated onboard attitude controller and operations software could support local sensor pointing and data-management decisions, subject to final orbital validation.
High-precision autonomous pointing and control could enable persistent imaging and monitoring payloads in low Earth orbit; the InspireSAT flight status remains under review.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.
