How it works

The one-sentence version

Everything — phones, the drone, satellite beacons — reports to a shared server in the cloud, and that server keeps every screen showing the same live map.

Why the server is in the cloud, not the village

Starlink is excellent at calling out but does not let outside computers call in (a limitation called CGNAT). A server in Quinhagak would be invisible to Eek, Goodnews Bay, and the Somewear system. A small rented cloud server (~$12–24/month) has a public address that everything can reach — and every part of our system only ever needs to call out.

What happens when the internet goes down

The system degrades gracefully instead of failing:

Maps keep working. Every device carries downloaded maps of our operating area — that’s policy, not luck. Searches happen beyond cell service, so the map on your screen never depends on an internet connection. The server hands out map downloads between missions; it is never needed during one.
Satellite beacons keep working. Somewear uses Iridium satellites, not Starlink — searchers stay on each other’s maps and can still message.
Phones on the same WiFi still see each other. TAK apps share positions directly on a local network without any server.
The drone still flies and records. Video sharing to remote viewers pauses; local operations continue.
(Future) Meshtastic radios add a third layer that needs no infrastructure at all.

What each person carries

Role	Carries	Sees
Searcher	Phone with ATAK/iTAK + a Somewear beacon	The whole team + drone on their phone
Drone operator	Skydio controller (its screen runs the map too)	Flight view + team map
Coordinator	Any computer with a browser (CloudTAK) or WinTAK	Everything, on a big screen

Is it private?

Yes. Connections to the server are encrypted, each member gets their own login/certificate, and the server is ours — no public map, no public video. (Somewear and Skydio see their own devices’ data, as they do today.)

Ocean conditions on the map

Three wave buoys float in Kuskokwim Bay — off Quinhagak, Mud Point, and the Halibut grounds. Every 15 minutes the server checks each buoy’s latest report and places it on the shared map as a marker. Tap a buoy to see the wave height, how often the waves are coming, which direction they’re coming from, and how many minutes old the reading is.

If a buoy stops reporting (dead battery, winter pull-out), its marker fades after a couple of hours — a faded buoy means “don’t trust these numbers,” never “the water is calm.”
