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

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.

• 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

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 .
