A lot of actors of the L1 low-cost RTK market have been emerging these months. U-Blox plays a relevant role in the miniaturization of GNSS chips for mass-market. Drotek and U-Blox are collaborating in order to produce the most reduced RTK board.


Market has shown that there are clearly two types of customers :

  • the ones  who like plug-and-play boards, but who still like to dig into hardware/software, eager to collaborate on any aspect. This is why we have created SMARTNAV RTK (http://drotek.io/1PodT25)

  • the others who only want simple-approach and reduced-form factor products without paying any attention to technical details. This why we are integrating M8P on our boards.

For the first tests we have used our XXL board and placed M8P on it. (http://drotek.io/1SQ5hCo) This version of M8P is capable of handling both base and rover states.


So we configured base in order to deliver RTCM correction messages over a 433 MHz radio link and rover to receive them. These are the first results :



We got to “float” position without any problem, and deviation map showed great results in this first short test!


Drotek is ready to manufacture, waiting for U-Blox first delivery! At this stage we still do not have pricing information.


Stay tuned on drotek.com !

Good marketing :)

What about the "ghost product" M8U with integrated IMU. Would enjoy hearing any information from your partner.

How the hell did you get one to play with?  I was told not until the summer.

Comment by Nikola Rabchevsky on April 16, 2016 at 7:53am

How long does it take to get to float and fixed RTK from power up?

@Maxime : we haven't worked with M8U yet, but looking forward to do it!

@Nikola : we have been working directly with U-Blox. This was a first test, so we did not measure accuracies or timings precisely. Just to let everyone know it is functional and coming!

Droetek units are great!
What about UAVCAN port on your boards for reliable results? Are you considering that?

Comment by Kevin Lopez Alvarez on April 16, 2016 at 10:00am
Not for the moment but probably on a near future!

@Nikola I've been talking to u-Blox about RTK for over a year. I didn't really want to mod my Drotek XXL M8T, but they conveniently have the serial TX/RX and power headerized so connecting it to a HM-TRP (3DR) type radio would be a breeze. And it's a perfect form factor.

Any updates or word on this product?, is the  XXL board with a M8P chip coming out soon?

Comment by DROTEK on August 12, 2016 at 6:22am

Yes an with an incredible form factor. Really soon so stay tuned!
