This rule triggers notifications when a device loses its GPS signal, often due to being indoors, underground, or in an area with poor satellite visibility, and when the signal is subsequently regained. By receiving these notifications, you can stay informed about the status of your assets' locations, even in challenging environments. This rule is particularly useful in environments where GPS signal coverage is unreliable, such as construction sites, warehouses, or underground facilities. Ensuring that your GPS device maintains cellular and internet connections is crucial for receiving these alerts when the GPS signal is lost and recovered. ## Rule settings This rule is cloud-processed, meaning the server software monitors when the GPS signal is lost and when it is recovered. You can apply this rule to multiple GPS devices simultaneously, as long as the GPS devices support this event type and it is integrated into the Navixy platform. For common rule settings, see the [Rules and Alerts](/docs/user/guide/events-and-notifications.md). ## System operation details * **Reset timer:** The **GPS signal lost/recover** alert has a 10-second reset timer, meaning the alert doesn't trigger more frequently than once every 10 seconds. If an event occurs during the reset period, it is omitted by the platform, including in reports. * **Multiple devices:** You can select multiple GPS devices to monitor under this rule, as long as the GPS devices support GPS signal lost/recover events and the feature is integrated into the platform. This allows you to manage multiple devices efficiently. * **GPS-independent event alert:** The platform registers and displays this event even if it is received in a message without valid coordinates, ensuring you are informed regardless of the event's location. The Inside/Outside settings for geofences are ignored in such cases, as the platform prioritizes displaying potentially critical events. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://navixy.com/docs/user/guide/events-and-notifications/device-positioning/gps-signal-loss-and-recovery.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
