Emergency Sat-Com SOS Module
Shubhan R September 8, 2022
1 Project Overview
1.1 Motivation
Every year, 200000 people get lost on a trip to a remote place without internet connectivity and mobile signal. Many of them are rescued by chance by other travellers who help them back to safety. As, this happens by chance, 10000 people go missing every year and are never found alive again. Our device aims to be an emergency SOS module, which can be used from anywhere in the world irrespective of whether there is mobile and internet connectivity.
1.1.1 Summary
There are over 50000 satellites that can be contacted directly through satellite communication technology. Our device would directly communicate with the satellite, which redirects the message to a ground station. The ground station can then send a rescue team to those GPS coordinates.
1.2 Novelty
This will be a low cost device and it can be bought by anyone. The current devices are very expensive.
2 Architecture and Implementation
• The module will be designed like a chargeable button phone and will have a radio communicator that directly communicates with a satellite when there is no Wi-fi or mobile signal around.
• The device will also have a GPS module.
• The module will have a LCD screen that displays options.
• There will be different options for different types of emergencies and this along with GPS Location will be broadcast to the satellite.

• To prevent accidental SOS Signals, they will have to type out a specific pattern of buttons for the device to be activated.
• The signal will be redirected to a ground station, and a rescue team would be dispatched to the location.
• The hardware and software will be kept as minimum as possible and the battery as large as possible to prolong battery life.
