Telemetric information

To receive telemetric data from your AscTec UAV, you can use the AscTec AutoPilot Control software (for WinXP or Win7). This software was designed to give you an easy way of reading sensor data from the low level processor (LLP) of your AscTec AutoPilot. It uses the predefined serial communication protocol of the LLP,  hence remember to connect your serial device to the LLP. As a connection you can either use the AscTec USB with the "AscTec USB to AutoPilot" cable. BILD Or you can use a wireless serial connection, which consists of an XBee pair (the UFO-XBee connected to your LLP, the USB-XBee connected to your ground PC) BILD.

Before you can use the AscTec USB or the USB-XBee, you need to install the following drivers: Download driver (executable setup) or see the FTDI driver download page. (after starting the executable, you should shortly see a black window. If it did not pop up during the first try, start the .exe one more time, then it should be installed successfully)

After installing the FTDI drivers, you can connect your AscTec USB / USB-XBee to your PC. Microsoft Windows will need a few seconds to install your device. You will see the pop-up Device driver software installed successfully! in your task bar when it is ready to use.

Now you can connect your AscTec UAV to the AscTec AutoPilot Control software. To do that, follow the next steps:

  1. Switch on your AscTec UAV.
  2. Start the AutoPilot Control executable.
  3. In the "Status Information" window, click on "Refresh". Now the comport of your AscTec USB is selected automatically. If not, choose the correct comport in the drop-down menu.
  4. Click "Connect".
  5. Then you will see a pop-up that asks, where you want to save the log file. This can be used to store the flight data on your PC. For further information about the log file go to the (% style="color: rgb(255, 153, 0);" %)AscTec AutoPilot Control software page(%%). Choose "Save" or "Abort". We recommend to save a log file for every flight. This helps you to track your flight activities, can be used for post processing and can help to reconstruct the behavior of the flight system in case of an accident.

    If the communication is working, "UART Comm" shows a green button and you can see the sensor data, which is polled from your AscTec UAV.

    If the serial communication is not working, you will see a red dot behind UART Comm. In this case, please retry the previous steps.

    You can poll for further packets by adding markers in the white boxes e.g. for RC Data.

    When you are not sure about the stick configuration of your R/C, you can check it by looking at the RC Data.
    Depending on the position of the stick you will see a value between 0 and 4095. Hence 2048 is approx. the center position of the stick. Since the calibration of the sticks can not be 100% accurate, it is totally normal that the value in the center position differs a little bit from 2048 (±16). Channel 1, 2, 3 and 4 are used for the flight commands, channel 5 is used to enable the serial interface and channel 6 selects the flight mode.

    When you are not sure about the stick configuration of your R/C, you can check it by looking at the RC Data.

     

    If the R/C is not connected successfully to your AscTec UAV, the UAV will switch to the Emergency Mode.

     

    The "Sensor Status" shows, if there are any warnings.
    Green: no warning. Red: a warning occurred. Please have a look at Troubleshooting to see what to do when warnings occur.

    Furthermore you can check out the battery voltage, the flight time and the GPS information.
