# Device positioning

- [GPS signal loss and recovery](https://navixy.com/docs/user/guide/events-and-notifications/device-positioning/gps-signal-loss-and-recovery.md): Get notified when a GPS device loses satellite signal and when it recovers, helping you monitor assets in tunnels, warehouses, or low-coverage areas.
- [GPS antenna disconnected](https://navixy.com/docs/user/guide/events-and-notifications/device-positioning/gps-antenna-disconnected.md): Detect when an external GPS antenna is disconnected from a tracking device and get notified immediately to restore satellite signal reception.
- [GPS jamming](https://navixy.com/docs/user/guide/events-and-notifications/device-positioning/gps-jamming.md): Detect GPS signal interference on your fleet devices caused by GNSS frequency jamming, a common anti-tracking method used in vehicle theft.
- [Location report on demand](https://navixy.com/docs/user/guide/events-and-notifications/device-positioning/location-report-on-demand.md): Request the current GPS device location via SMS when standard IP connections are unavailable. Get notified as soon as the location update arrives.
