Blog – NTRIP Base and CORS PX1122R RTK TRIMBLE – Volodymyr Maslovskyi


Hello ESPrtk User and Happy new year 2022 !πŸŽ„ ❄️ πŸŽ…πŸ¦Œβ˜ƒ

This is the ESPrtk NTRIP Base + CORS project of Volodymyr Maslovskyi

He uses ESP32 DEV kit and PX1122R modules.

Initially he had a problem with the hardware but then everything was resolved.

Then he experimented with building NTRIP Base station with ESPrtk WIFI and Ethernet.

Below are some of his pictures that he sent during contacting us via email and Facebook messenger.

We will continue to update on this project of his in the near future.

Hardware.

Warning !

For those who are intending to use buzzer on ESPrtk.

To protect ESP32 chip. Do not connect the buzzer directly to the ESP32’s GPIO12 pin.

Please use protection diode (or combine with NPN transistor as shown image below).


  • App Build : NTRIP/MQTT RTK Base Station+Rover+CASTER
  • ESP32 : ESP32 DEV KIT C Espressif ( ESP32_WROOM_32U or ESP32_WROOM_32UE CHIP)
  • RTK GNSS: F9P or PX1122R
  • Display: OLED SSD1306 0.96 inch or SH1106 1.3 inch( option !)
  • Ethernet: W5500 ( option !)
  • Power supply: 5V 2.5A Adapter
  • Other: LED , Button, Switch , 2.4Ghz WiFi Antenna , GNSS RTK Antenna, RJ45 Etheret cable, Micro USB Cable , 3.3V Active Buzzer , …

NTRIP RTK Basestation – PX1122R / F9P + ESP32 + TRIMBLE, TOPCON, John Deere – ESP32 RTK.

If you want to build your own CORS RTK SERVER Base station, read more here (Full instructions, connection diagram, how to configure):
DIY NTRIP CASTER CORS Server with ESP32 and free DDNS host name – F9P PX1122R ESP32 RTK.


Step 1 : Hardware connection – ETHERNET + Full standards.

For RTK Basestation applications with up to several months or years of continuous uptime, we always recommend users to use the W5500 Ethernet module for their systems to ensure a stable 24-hour connection !.

In addition, it is possible to add 1 buzzer on the ERROR LED pin (3.3V Active Buzzer) and 1 small OLED module to be able to see the operating status, (connection status, error, flow rate, etc.) of the whole. system .
