An active antenna on the roof received nothing until the modem's antenna supply was switched on (AT+CVAUXV=3050, AT+CVAUXS=1); then +5.5 dB over the passive one. The settings reset on every modem restart and AT&W doesn't keep them, so interface 03 is reserved as /dev/sim7600-at (ModemManager ignores it) and a udev-started oneshot re-applies them. gpsd now re-attaches via gpsdctl after re-enumeration. Verified with a live modem reset: antenna, LTE and the GNSS fix all recovered unattended. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

This file serves as the minimalist portal to other docs
What this repo is about
Jetson Orin Nano is an ARM SBC running a custom kernel Ubuntu (Nvidia Jetpack), so many things are not readily available.
