Source note: How to design trackers that work without GPS¶

Raw path: raw/processed/2026/how-to-design-trackers-without-gps.md

Summary

Long-form engineering article on GPS vulnerability (jamming/spoofing, environmental blocking), clarifying GNSS vs satellite IoT (e.g. Iridium-class messaging) roles, failure modes, and a taxonomy of non-GPS mitigation paths for asset tracking—oriented toward resilient product design rather than a single vendor datasheet.
