Four new tools transforming the SkyWalker-1 from satellite TV receiver into
a general-purpose RF observatory:
- skywalker-mcp: FastMCP server exposing 20 tools, 4 resources, 2 prompts.
Thread-safe DeviceBridge with motor safety (continuous drive opt-in),
input validation on all frequency/symbol rate/step parameters,
try/finally on TS capture, path traversal sanitization, and reduced
lock scope so emergency motor halt isn't blocked during long surveys.
- h21cm.py: Hydrogen 21 cm drift-scan radiometer at 1420.405 MHz with
Doppler velocity calculation, control band comparison, and CSV output.
- beacon_logger.py: Long-term Ku-band beacon SNR/AGC logger with auto-relock,
dual CSV/JSONL output, signal handlers, and systemd unit generation.
- arc_survey.py: Multi-satellite orbital arc census with USALS motor control,
per-slot catalog persistence, resume support, and defensive motor halt
on all error/interrupt paths.
Documentation: experimenter's roadmap guide + 4 tool reference pages (48 pages total).
