Update autodev state documentation to reflect progress in the Decompose phase, changing the current step from 5 to 6. Revise sub-step details to indicate a shift to phase 2, focusing on module layout for the Satellite Service and Tile Manager, and awaiting confirmation before product task decomposition. Additionally, enhance problem documentation to clarify the original still-image sample limitations and introduce the Derkachi representative fixture for improved data validation. Update references to the Tile Manager and Satellite Service throughout the documentation for consistency.

## Sensors & Integration
- High-rate **IMU** data is available from the flight controller via MAVLink.
- The provided sample imagery does **not** include synchronized IMU or ground-truth pose. Prototype validation may use public datasets or synthetic IMU injection, but final acceptance claims require synchronized navigation-camera frames, FC IMU/attitude/airspeed/altitude, emitted MAVLink messages, and ground-truth trajectory from a representative flight or replay rig.
- The original still-image sample does **not** include synchronized IMU or ground-truth pose. The Derkachi representative fixture adds cropped nadir video plus synchronized `SCALED_IMU2` and `GLOBAL_POSITION_INT` telemetry, which is enough for replay, synchronization, latency, VIO smoke tests, and trajectory comparison against the tlog GPS path. Final production acceptance still requires camera intrinsics, lens distortion, exact camera-to-body calibration, and representative synchronized navigation-camera frames, FC IMU/attitude/airspeed/altitude, emitted MAVLink messages, and ground-truth trajectory from a representative flight or replay rig.
- The system communicates with the flight controller via MAVLink. Telemetry plumbing uses **MAVSDK**; the `GPS_INPUT` injection path is implemented via **pymavlink**, since MAVSDK does not expose a native `GPS_INPUT` API.
- **Autopilot target: ArduPilot only** (with `GPS1_TYPE=14` for MAVLink GPS injection). PX4 is out of scope for the build; if it ever returns to scope it will use `VISION_POSITION_ESTIMATE`, not `GPS_INPUT`. (See `_docs/00_research/00_ac_assessment.md` Q-1.)
- The system outputs WGS84 GPS coordinates to the flight controller as a replacement for the real GPS module (MAVLink GPS_INPUT, AC-4.3).
