GNSS Cold Start vs Hot Start: Why Time to First Fix Is the Silent Battery Killer in Asset Trackers

A cold start burns 20× more power per GNSS fix than a hot start. Here are the firmware strategies — AGNSS, ephemeris caching, adaptive timeout — that extend IoT asset tracker battery life from 14 months to 38 months on the same hardware.
