///  - Szürke:      nincs eszköz kiválasztva
///  - Piros:       eszköz kiválasztva, nincs kapcsolat
///  - Narancs:     csatlakozva, nincs GPS fix
///  - Sárga:       autonóm GPS (quality 1)
///  - Kék:         DGPS (quality 2)
///  - Világoszöld: RTK Float (quality 5)
///  - Zöld:        RTK Fix (quality 4) ← ideális állapot
