Open any .sckflight file and watch the entire mission play back — animated GPS track on Google Maps, altitude profile chart, event timeline, and all 8 telemetry channels updating in real time.
Position marker moves on Google Maps as playback runs. Launch, apogee, and landing pins always visible.
Baro alt (cyan), GPS alt (blue dashed), temperature (orange dotted). Vertical cursor tracks current playback position.
1x, 5x, 10x, 30x, 60x playback. Watch a 2-hour flight in 2 minutes. Scrub bar to jump anywhere.
LAUNCH, APOGEE, BURST, LANDING automatically detected with timestamps. Max altitude, flight duration, burst status.

MicroPython firmware for the Raspberry Pi Pico. Handles ESP framing, fused GPS + barometric telemetry beacon, camera capture, SD card file management, and chunked RF file transfer.
Main pipeline firmware. Fused GPS + MS5611 barometric beacon every 10 seconds. All sub-opcode handlers: PING, TEMP, SNAP, LIST, GET_INFO, GET_CHUNK, DELETE, GET_GPS, GET_BARO. Camera init, SD card management, GPS airborne mode (50km rated).
⬇ Download main.pyMicroPython SPI SD card driver. Required dependency for main.py. Must be installed on the Pico filesystem before main.py.
⬇ Download sdcard.pyUse Thonny to copy both files to the Pico. Install sdcard.py first, then main.py. The Pico runs main.py automatically on power-up. See the Pico Project page for full setup instructions.
