AirDrop is an autonomous Drone system, based on the open source dji naza interface interface. It's ment to deliver payloads quick and easy without relying on custom or second hand flight controller implementations. Instead, it relies on an interface, for any flight controller (currently using the DJI Naza V2), which allows the system to operate safe and predictable as well as open source. It consists of a number of ROS packages containing the core and mission critical nodes. The Web Interface for remote controle can be found here.

Command & Control (CC) node (planned)
The CC node handles all requests that require the drone to move or change position
in physical space by offering ROS services. It also manages all state variables, which makes it to the most important package. -
GPS Node
Node that constantly publishes GPS position data under thegps_rawtopic. The data is read via the raspberries serial port and comes directly from the GPS Unit's serial output(tx) which is also linked to the Naza V2. The original code to decode the gps protocol is from pawelsky and has been adapted to raspberry c++ standards and can be found here -
MN Node
Node that parses and then runs missions(files) by calling services
provided by CC node.
