-# pinephone GPS happens in EG25 modem
-# serial control interface to modem is /dev/ttyUSB2
-# after enabling GPS, readout is /dev/ttyUSB1
-#
-# minimal process to enable modem and GPS:
-# - `echo 1 > /sys/class/modem-power/modem-power/device/powered`
-# - `screen /dev/ttyUSB2 115200`
-#   - `AT+QGPSCFG="nmeasrc",1`
-#   - `AT+QGPS=1`
-# this process is automated by my `eg25-control` program and services (`eg25-control-powered`, `eg25-control-gps`)
-# - see the `modules/` directory further up this repository.
-#
-# now, something like `gpsd` can directly read from /dev/ttyUSB1,
-# or geoclue can query the GPS directly through modem-manager
-#
-# initial GPS fix can take 15+ minutes.
-# meanwhile, services like eg25-manager or eg25-control-freshen-agps can speed this up by uploading assisted GPS data to the modem.
-#
-# support/help:
-# - geoclue, gnome-maps
-#   - irc: #gnome-maps on irc.gimp.org
-#   - Matrix: #gnome-maps:gnome.org  (unclear if bridged to IRC)
-#
-# programs to pair this with:
-# - `satellite-gtk`: <https://codeberg.org/tpikonen/satellite>
-#   - shows/tracks which satellites the GPS is connected to; useful to understand fix characteristics
-# - `gnome-maps`: uses geoclue, has route planning
-# - `mepo`: uses gpsd, minimalist, flaky, and buttons are kinda hard to activate on mobile
-# - puremaps?
-# - osmin?
-#
-# known/outstanding bugs:
-# - `systemctl start eg25-control-gps` can the hang the whole system (2023/10/06)
-#   - i think it's actually `eg25-control-powered` which does this (started by the gps)
-#   - best guess is modem draws so much power at launch that other parts of the system see undervoltage
-#   - workaround is to hard power-cycle the system. the modem may not bring up after reboot: leave unpowered for 60s and boot again.
-#
-# future work:
-# - integrate with [wigle](https://www.wigle.net/) for offline equivalent to Mozilla Location Services
