Flight Computer¶
Context¶
Dual deployment requires electronic altimeter to fire ejection charges at correct altitudes. Alternative is single deployment using motor delay.
Equipment Ordered¶
- CATS Vega - Flight computer
- CATS Ground Station - Telemetry receiver
Why CATS¶
Fully Open Source - hardware designs in Altium format. This fits my background perfectly. Could copy designs and order own PCBs, but purchased to support the project.
Shipping Status¶
Package shipping from Switzerland, may arrive too late for 24 Jan launch.
Decision: Pending¶
Option A: Motor Delay (Simple)¶
Single chute deployment using motor ejection delay. Often recommended for L1 certification to keep it failproof.
Pros:
- Simpler, fewer failure modes
- Traditional L1 approach
- No electronics dependency
Option B: Electronic Dual Deployment¶
Use CATS Vega for drogue at apogee, main at lower altitude.
Pros:
- Closer-to-pad recovery (what Peregrine is designed for)
- Decades of sensor/actuator experience gives me an edge
- Arguably safer for someone with electronics background
Cons:
- More complexity for certification flight
- Equipment may not arrive in time
Outcome¶
If CATS arrives in time → likely go electronic dual deployment
If not → motor delay single deployment
