This is the tool to configure RTK Skytra module.

This article shows you how to use ESPrtk to configure Skytraq's NS-HP GL/BD/GN/GN2 module in Rover mode (export NMEA data to TX1 port).

Hardware connect

ESPrtk	NS-HP-BD NS-HP-GL	NS-HP-xx	Other
TX-UART1	RX1	RX1	RX-UART Conigure
RX-UART1	TX1	TX1	TX-UART Conigure
TX-UART2	RX2	RX2	RX-UART Conigure
RX-UART2	TX2	TX2	TX-UART Conigure

After connecting the ESPrtk to the Naspark module, start ESPrtk in "WEB Configure" mode, access the "Navspark" tab and start communicating with the Navspark module with the baudrate and port. (See more Tab Navspark Configure ).

Configure to run Rover mode

To use NS‐HP‐GN2 as RTK rover, connect antenna, place antenna at location with clear open sky view, apply base data to UART RX2 input and apply power, NMEA result will come out from UART TXD output.

The base data may come from a NS‐HP‐GN2 base sent over wireless radio, or a remote RTCM 3.x base station within 30Km range retrieved by NTRIP client over Internet and send over Bluetooth‐to‐Serial or USB‐to‐Serial interface.

From GNSS Viewer RTK pull down menu, select Configure RTK Mode, select RTK rover mode and update to SRAM+Flash

Configure type NMEA message output

Configure talker id format as $GNxxx or $GPxxx
