There is a switch on the hat , by turning it on and off sequentially, one can send a emergency distress message to some known people or appropiate authority. The message contains a map link to the location of the hat . And this action can be accompanied by recording of video.
By leaving the same switch on the hat on, after 7s the hat gets into track mode, where it continously broadcasts its location continously once every 3 seconds. Its location data can be accessed from laptop or phone. Similar to the previous mode hat can me made to record automatically and save it on onboard sd card or broadcast video to the remote observer.
After the switch is turned off hats moves to standby mode where it stops broadcasting. And becomes just like another normal hat.
Ublox NEO-6M gps

Raspberry PI 3B+
It is a low cost powerful single board computer with wifi and bluetooth suppot, it controls all parts and interfaces the webcam to show live footage as well as save recording on its onboard sd card..
Popular microcontroller based on ATMEGA328P chip , reads the raw data from the gps and extracts the coordinates. It interfaces with a switch and operates two different modes of operation Track mode and Distress call .
