This repository holds all program code for the sensor component, drone communications, and client application used to drive the Cellular Search and Rescue system.

A great place to get started is the documentation in the project wiki. This also contains reference materials for the configuration files and automation extensibility framework.

The "bts" folder contains Yate and YateBTS, along with their patches to support the Nuand bladeRF x40. This software is required to run the cellular base station software on the cellular sensor.

The "ocp" folder contains the application responsible for managing the lifecycle of the BTS, as well as encoding and transporting commands and event data between the operator's controller software and the BTS.

The "client" folder contains the controller application to fly the drone, send commands to the BTS, and interpret events from the cellular sensor.
