Info / Download

The GPX viewer is a simple program with which it is possible to view the GPX log files recorded by the MikroKopter.
All telemetry data are recorded in these log files during a flight.

The GPX viewer functions at a glance
- Display of all telemetry data of the copter
- Errors are highlighted in color
- Problematic values are highlighted in color (e.g. Magnetic field deviations)
- Status bits of the MK are evaluated
- GPX file can be exported to Google Earth
- Additional information from the GPX file can be displayed (e.g. setting info, license info, firmware info)
- Data are given units and converted if necessary
- You can create your own graph from the values
- The columns can be moved
- Geo data can be exported for Agisoft Photoscan and Pix4D

The program GPX-Viewer can be downloaded here: Download

download GPX Logfile

To download the .gpx Log connect your MikroKopter with your Computer
and start the KopterTool. Here "click" on the Button SD Card....
Here the required .gpx log file of the flight can be selected and saved on the computer.

Larger files may take a few minutes to download.
If you want to access the log data faster, you can also remove the SD card from the copter and read it out directly with the PC.

File

Open GPX
-> To open a log file in * .GPX format
Save GPX
-> To save a log file
Show GPX
-> Shows information about the opened log file such as error messages etc.
Open in Google Earth
-> Opens Google Earth and shows the flight graphically.
Connect altitude to Ground in GE
-> If this option is activated, the height is marked in Google Earth with lines perpendicular to the ground.
Use raw GPS altitude
-> If this option is activated, the altitude calculated by the GPS is entered for the export to Google Earth and not that of the air pressure sensor.
Create photo logfile ...
-> To create an export file for Agisoft Photoscan and Pix4D
Open in Texteditor ...
-> The GPX file is opened in a text editor
Exit
-> Closes the GPX viewer

Charts

-> If you have created your own graphs / charts, they can be added here.
Select chart files
-> Show charts from the directory of the GPX viewer

The GPX log file


Latitude value in decimal degrees	Longitude value in decimal degrees	Altitude value from the GPS module	UTC time from the GPS module


Number of satellites received	Flight time in minutes: seconds	Display of the various ErrorCodes	Current FlightCtrl status


Current GPS status	Voice output HoTT telemetry	Barometric altitude measured by the air pressure sensor	Rate of climb of the copter (in m/s)


Voltage of the LiPo (in Volt)	LiPo-Current (in Ampere)	Consumed capacity (in mAh)	1: Yaw Gyro Stabilized Compass Value 2: Compass raw value 3: Compass Setpoint 4: Corrected compass value (declination)


Strength of the magnetic field in %. Value should be ~ 100%	The first value shows the inclination of the vector from the magnetic compass. The second value indicates the calculated error compared to the theoretical value of the location	Pitch angle (in Grad)	Roll angle (in Grad)


Display of the individual motor currents	Display temperature of the individual motor controllers	Motor fault counter Motor1, ... Motor8	Available energy of the motor controller (0-100%)


First value: current GAS value Second value: Calculated value for floating gas	Error counter for I²C bus	Error counter for SPI bus	Analog inputs from the NC (1024 = 3,3V)


First value: Setpoint Nick Servo in degrees Second value: Setpoint Roll Servo in degrees Third value: waypoint nick setpoint in degrees	First value: Name of the current destination waypoint (e.g. P12) Second value: Number of the current destination waypoint Third value: total number of waypoints Fourth value: Current value of the WP event	Counter for switching output OUT1	Angle from the copter to the target


Distance from the copter to the target	GPS course over ground (regardless of the compass value)	Basic speed of the copter (in cm/s)	Vertical speed of the copter (in cm/s)


Current values of the RC sticks in the following order: Nick; Roll ; Yaw ; Gas ; Ch5, ... Ch16	Influence of the GPS mode on the RC sticks in the following order: Nick, Roll, Yaw, GPS-Mode GPS-Modes: '-' = no GPS fix '/' = OFF '?' = Coming home, home position unknown (PositionHold is activated instead) 'H' = Coming home 'W' = Waypoint flight 'D' = Dynamic Position Hold 'P' = Position Hold 'm' = manual control	Quality of the PPM signal (NOT the signal strength of the receiver)	Raw GPS Altitude in m


1: GPS update rate in 0.1Hz (50 = 5,0Hz) 2: GPSData_Flags 3: Sat-fix

Charts / Graphen

You can graphically display certain values of the recorded flight separately in a separate window.
These are opened automatically when the program starts. All windows can also be closed under the "Windows" tab and only individual graphs can be displayed.

The following charts are already included with the GPX viewer:

Altitude

BL-Ctrl Temperatures

Compass

Throttle/Yaw

GroundSpeed

Nick/Roll

OUT1+2

StickGAS/Altitude

Current

WP-Event

X-Achse-Current

Voltage

Create your own graph

If you want to display certain values in a separate window, you can do this via an extra ".ini" file.
The name of the ".ini" file must then start with "Charts-" and be in the same folder as the "GPX-Viewer.exe".

Example: Display capacity over flight time
If you want to display the capacity over the flight time, the file can be called "Charts-Capacity.ini".
The content can look like this:
- [Chart1]
  ChartName = "mAh"
  Series1Ident = "Capacity"
  Series1Name = "mAh"
The display would then look like this:

Export geospatial data

With the current version of the GPX viewer it is possible to export the appropriate geodata for Pix4D and Agisoft Photoscan.

To do this, proceed as follows:

click in the GPX-Viewer ->Create photo logfile...

In the following window you select the line on which the first photo was triggered. You can recognize this by the column [ShutterCnt]

Directly below you select the first photo that was created by the waypoint flight.

Now you have to give the output file a name and select the 3D program for which the file is to be created. If you click on "Start ..." the export file is created.

From here the respective programs continue.

Agisoft Photoscan

If the photos have been loaded into Agisoft Photoscan, click on the symbol for importing the geographic information in the "Reference" tab.

Here the program already offers the option of selecting the format in which the import file is available.

Pix4D

If you have loaded photos into Pix4D without geo information, this will be displayed

With a click on "From File ..." the file generated by the GPX viewer can be read in. Once this is done you will see a green tick as confirmation.
