TINY RTK : The world smallest precision GPS ... and the cheapest

 

Ultra precise positioning at low cost and reduced form factor.

We just release TINY RTK, the world smallest RTK GPS based on u-blox NEO-M8P.

Size: 23.5 x 24.5 mm

Key features

  • Centimeter‑level GNSS positioning for mass market, based on U-Blox M8P
  • Integrated Real Time Kinematics (RTK) for fast time‑to‑market
  • Smallest, lightest, and best energy‑efficient RTK module
  • Receiver type: 72-channel GPS L1 , GLONASS L1, BeiDou B1, GALILEO E1
  • Nav. update rate: up to 8 Hz
  • Position accuracy: 2.5 cm
  • Connectors: SMA, USB, JST-GH
  • Data link: whatever can be connected to a UART : Bluetooth, 433-868-915 MHz radio link, XBee, WiFi...

We've decided to launch an INDIEGOGO campaign to lower chip prices by ordering mass. 

If you're interested by precision GNSS and want a Plug&Play solution at an incredible price ... TINY RTK is designed for you

@Olivier WIth regards to battery life, I'm thinking of the Solo with it's stock GPS taking a lot longer than it should to get an initial fix.  As for update rate, if your movements are slow and smooth, the INS code can make decent predictions but if you're traveling very fast with abrupt changes in direction, you need things to run a lot faster.  It boils down to your use-case.  High-end INS systems (in the several thousand dollar range and up) have position updates at 40 or 50 Hz.  Consider trying to execute a high-speed 90-degree turn in a fraction of a second.

What is the easiest way to give this board corrections from a virtual RTK station? Here in Spain they are widely available and everyone is using those, no one uses real base and rover :)

I would love to implement this in surveying drones

Congrats on a great looking product

@Satyabrata Satapathy :

Sorry for the delay, we have been working this week-end to add another fully integrated version. Please have a look at our Indiegogo campaign.

@AJ152 : 

We have added some basic documentation on our website. Rover module is already compatible with Pixhawk (driver is the same). Differential data encapsulation from base in MAVLink protocol is work in progress. However it is already possible to have it fully functional with a dedicated datalink (see our documentation).

@Jose : 

What messages can your correction service provide? M8P works with RTCM 1005, 1077 and 1087 by default for GPS and GLONASS (it has also BEIDOU), and u-blox will probably extend compatibility to other messages. Do you usually work over 3G connection?

ppk is not possible?

with that not needed to online transfer data.
