Three items, new in v0.4.7, let players track each other’s helicopters. None of them spawns unless you add it to your loot or traders — see Types & Events. To turn the whole feature off, set tracker.trackerEnabled to 0.

Hiding a tracker

  1. Stand next to the helicopter, within about 20 m, standing or crouched, with the GPS Tracker in your hands
  2. Hold Hide GPS Tracker for 8 seconds
The tracker is used up and hidden on the aircraft. It does not appear in the helicopter’s inventory. It works on every helicopter, but it cannot be done from a seat or from inside the cabin, and only one tracker fits each helicopter — a second one will not pair. Each player can have only a set number of trackers running at once (tracker.maxPerPlayer, default 3).

Following it

Use the Tracker Receiver in your hands (Open Tracker Map). It opens the Pilot Panel map in tracker view, where each helicopter you have tagged shows as TRACKED HELI 1, TRACKED HELI 2 and so on, as a ring at its last signal with how long ago it came in.
  • The tracker reports every 90 seconds (tracker.pingSeconds), starting 5 seconds after it is hidden
  • Each report is placed up to 150 m away from the aircraft’s real position (tracker.blurMeters), so you see the area, not the exact spot
  • Only the player who hid it receives its reports. If they log off, the last report is waiting for them, with its real age, when they come back
  • The battery lasts 2 hours of real time (tracker.batterySeconds), flying or parked. When it runs out the tracker stops and is gone
  • Trackers stay on the helicopter through server restarts, and keep reporting from a wreck until the battery runs out

Noticing one

The crew can tell something is on board, unless the server turns these warnings off (tracker.ownerWarnings = 0):
  • Every time the tracker transmits, everyone aboard hears a short burst of radio static (unless they have set Alert volume to Off in the Pilot Panel), and the cockpit GPS shows an RF symbol for a couple of seconds if it has power
  • After 10 minutes of flying with a tracker on board (tracker.warnAfterSeconds), everyone aboard is told UNKNOWN TRANSMITTER ON BOARD, and the Pilot Panel shows it too

Removing one

  1. Hold the Signal Scanner against the helicopter and hold Scan For Transmitters for 10 seconds. It tells you whether it found one
  2. If it did, hold Remove Hidden Transmitter for 6 seconds within the next 2 minutes. Only the player who scanned can do this
The tracker is yours now: you get a working GPS Tracker, ready to hide on someone else’s helicopter.

For admins

The helicopter list in the Admin Panel marks a tracked helicopter [TRACKED], and its details show who hid the tracker and how much battery it has left, with a REMOVE button (needs the heli.list.repair permission). Hiding, removing and a tracker’s battery running out are written to the activity log as TRACKER.

Settings

All in the tracker section of mod_config.json, and in the Admin Panel’s Helicopter Tracker group.
