is the lightest multiband GNSS board in the market (7.8g only).  Based on u-blox ZED-F9P module, it can work as a standalone product to provide cm level precision or as moving base in combination with the simpleRTK2B board to provide extremely accurate heading.

Centimeter level precision
<1cm precision with base-rover
<1cm precision with NTRIP corrections
<5cm precision with SSR corrections
<1.5m in standalone mode
<1m in standalone mode with SBAS coverage

Advanced configurations
Unleash your creativity with simpleRTK2B. It supports multiple rover configurations, moving base, …

Suitable for drones and ultra-lightweight projects
6pin JST-GH connector for Pixhawk + EXTINT pin for photogrammetry applications (both are not shown in the protoype pictures but will be available in the production version)

Typical convergence times of modules based on:
– Single band RTK (NEO-M8): <60s
Multi band RTK (ZED-F9P): <10s

• Reduces convergence time
• Increases ambiguity fixing rates
• Increases overall cm-level position availability

• GPS & GLONASS: readily available in L2C/L2OC
• Galileo: full E5b constellation by ~2020
• BeiDou: B2I available until migration to B2a

Raw GNSS measurements
Read the raw data from the satellites without any post-processing

Radio link flexibility
simpleRTK2Blite can be used with almost any radio link: wifi,  BT, ISM, … with XBee format by stacking it on top of the module. We offer 3 options: medium range, long range and 3G. Check our store to learn more!

RoHS compliant


simpleRTK2Blite supports different operating modes, is extremely flexible and is compatible with your existing radios and simpleRTK2B boards

Standalone – simplest way of reaching 1m position accuracy without range limitations
The most basic configuration is to use simpleRTK2Blite as a standalone GNSS application board.
Connect it to your ultralight weight project and get your position in seconds.


Heading – get extremely accurate heading without range limitations
This is the first low cost, ready to used module with the moving base capability.
Simply stack the simpleRTK2Blite on top of the simpleRTK2B board and place the two GNSS antennas where you want to measure the heading.
Heading and baseline distance will be calculated online, without any kind of postprocessing.

RTK positioning – get cm level accuracy
Use the simpleRTK2Blite with RTK corrections exactly like the bigger simpleRTK2B board:

  • Use a base-rover or base multi-rover configuration to supply corrections with your favorite radio module in XBee format
  • Supply NTRIP corrections via your computer, 3G modem or smartphone via Bluetooth

RTK positioning + heading – get cm level accuracy and accurate heading
Combine simpleRTK2Blite with simpleRTK2B and your preferred corrections source to get extremely accurate readings of position and heading.

  • Provide corrections from a base station
  • Supply NTRIP corrections via your computer, 3G modem or smartphone via Bluetooth
