Bullet GCSS is a high caliber ground control station system designed for the 21st century lifestyle.
Bullet GCSS allows an UAV pilot/operator to get the most important telemetry data right on his/her SmartPhone or computer screen. Information such as aircraft location, distance, altitude, battery status, navigation status are always available.
The main differences between Bullet GCSS and other traditional ground station systems are:
There are two fundamental parts on Bullet GCSS: The Modem and the User Interface (UI).
Modem talks to the Flight Controller on the aircraft to get the telemetry data, and sends this data to a MQTT Broker on the Internet.
The UI is connected to this same MQTT Broker, and every time it gets a new telemetry message, it'll display it on the screen.
