How it works:
A connection to the Naza GPS puck give the positioning and altitude information. Direction, speed, and distance are derived from this data.
Connections from the Naza LED module are decoded to determine the Mode.
The Naza Gimbal servo output (M1, M2) are the source for the roll and pitch data.
A provided special connection to the main battery is converted to Battery Volts.
An AttoPilot power sensor connected between the main battery and the multirotor gives battery voltage, current, and condition (% remaining).
What it can do:
The Naza data seen on the Mission Planner ground control station is nothing short of fantastic!
Not only do you see all of the above information on a very well designed GUI interface including flight path and current position, you can get realtime audio announcement of critical flight data such as altitude, ground speed, mode, and battery condition. Mission Planner can play back an automatically saved log file. The log file can be converted into a .kml file that will generate a Google Earth presentation that shows the flight path in mode annotated segments.
What it can't do:
Airframe heading is not available. Realtime gyro and accelerometer information are not available. Radio transmitter channel position and motor output levels are not available.
Transmission is one way only. Data, commands, or parameter changes can not sent from the Ground Control Station to the FBOSD. Waypoint flying is not possible. Many of the Mission Planner capabilities are not available.
