Want to track a drone with pre installed GPS device

Nikhil6 years ago

I have a DJI Drone spark series.(https://developer.dji.com/products/). Is it possible to sent its location to GTS real-time so that we can know the location of the drone real time from anywhere.

If this is possible then how can i make a position request from the GPS inside the drone to our traccar server. As I understand to make a position request we need to use osmand protocol to the following url http://localhost:8082/api/positions.

Any help on the workflow would be highly appreciated.

Regards,
Nikhil

Your drone needs to be able to report location. If it can I would need to know the format that it uses to send it.

Here is the information I have regarding the source of GPS in the drone model:

DJI Products come with built-in consumer satellite positioning systems that use GPS and GLONASS satellite constellations. Consumer grade satellite positioning can have position errors of several meters.

The DJI DRTK positioning system is an accessory compatible with the M600 and A3 flight controller that allows centimeter level positioning. DRTK is a real time kinetic satellite positioning system that uses GPS+GLONASS or GPS+Beidou constellations (depending on DRTK model).

The system requires both a base station and mobile station receiver, which are connected together through a wireless link. The base station receiver is deployed at a known location on the ground, while the mobile station is deployed on the aircraft. Both base station and mobile station will experience similar satellite signal errors at the same time. As the base station is at a known location, it can send real time correction information to the mobile station, resulting in centimeter accurate positing information for the mobile station relative to the base station.

The mobile station comes with two antennas which can be deployed on opposite sides of the aircraft. As the position of both antennas can be combined into a heading vector that can often be more accurate than compass heading in the environments with high magnetic field interference (like near large metal structures, or high voltage lines).

Hey Nikhil, Anton needs to know if the device is able to send its position over a network. So either the base station or the drone needs a mobile internet connection to send its position over to a traccar server.

All info you provided was that the drone has a super duper way of high accuracy GPS location function.

The component that takes the coords, wraps it in a TCP/IP packet, sends it through the internet, ... is missing.
