KAVAN Smart PRO GPS2 Logger - Instruction manual
Introduction
The GPS LOGGER is a telemetry device that offers fast and accurate real-time position detection and feedback. It uses multiple satellite navigation systems to achieve maximum precision and resolution. Logging of all the data is possible due to its large integrated Flash memory. The logged data can be downloaded and analyzed on a computer using the free MAV Manager software.
Features
- Small dimensions, high measurement accuracy
- Large industrial memory for data logging
- Latest generation GPS chipset supporting multiple satellite systems
- 3-axis magnetometer/compass for external navigation purpose
- Backup supercapacitor for fast position fix after powering off
- Voltage measurement and logging
- Automatic telemetry detection: Duplex EX, Hott, MSB, S.Bus2, P2Bus. Automatic timezone detection
- Configuration through the transmitter

| Parameter | Description |
|---|---|
| Timestamp | Current precise GPS time. |
| Latitude | Coordinate North/South. |
| Longitude | Coordinate East/West. |
| Status | Indication of activity (1=got fix) or fault condition. |
| Sattelites | Number of detected satellites. |
| Abs. altitude | Altitude above the mean sea level. |
| Distance | Distance from the “Home position”. |
| Speed | 2D/3D speed referenced to the ground. The speed type can be set in the configuration. |
| Rel. altitude | Altitude relative to the “Home position”. |
| Course | Direction of the flight (heading). Values in range 0°–359°: 0° = North, 90°=East, 180°=South, 270°=West. Compass heading is used if the speed is zero. |
| Azimuth | Position of the model with respect to the “Home position”. Values in range 0°–359°: 0° = North, 90°=East, 180°=South, 270°=West. |
| Temperature | Internal temperature. |
| Magnetometer X/Y/Z | 3-axis magnetometer value. It can be used for further calculations. |
| Voltage | Receiver voltage. (logged only) |
| Trip | Distance travelled during the flight. (logged only) |
Installation
Connect the GPS LOGGER to the receiver telemetry port. Place the device on top of the plane, so that the internal patch antenna is not shielded in any direction. Shielding materials, such as metal, carbon or anything conducting, can reduce the performance of position detection. Additionally, make sure that the 2.4GHz antennas are located at least 20cm or more from the GPS LOGGER. Try to avoid any mechanical stress on the sensor and avoid any close contact with components producing heat (such as engines or speed controllers). Use a soft double-sided adhesive tape, or Velcro as an alternative.
For good performance of the integrated magnetometer it is necessary to install the device at least 20cm away from magnetized objects and cables powering servos/motors. In addition, please keep the device orientation with respect to the flight direction as shown in the picture below.
Power up the receiver with GPS LOGGER attached. The red LED flashes once to indicate correct initialization. After a few seconds (or minutes if the device has been unpowered for more than a day), the device reports “3D position fix”. From this moment on, the device can start logging depending on the condition set in the configuration. The logging is indicated by a flashing LED synchronously with the sampling rate.
Each time the logging is started, a new file is created at the internal Flash storage. The log files are named according to current date and time in the following format:
