    evk-tau1312

    TAU1312-evk datasheet

    1.1 Requirement

    1.1.1 Hardware

    • RTK EVK(TAU1312) *1
    • GNSS antenna*1
    • USB cable*1
    • GNSS antenna cable*1
    • Power bank(optional)

    1.1.2 Software


    Tips


    1.2 Specifications

    • support 1/2/5Hz for rtk output rate
    • support 1/2/5/10Hz for standalone output rate
    • support rtk rover mode and base mode

    1.3 Guide

    Satrack


    Tips TAU1312 support the following working mode:

    • GN_DGNSS_NONE
    • GN_DGNSS_SBAS
    • GN_DGNSS_RTD
    • GN_DGNSS_RTK_FLTINT
    • GN_DGNSS_RTK_FIXINT

    1.4 Standalone mode

    1.4.1 set to standalone mode

    set DGNSS to none

    1.4.2 set PVT output rate

    set output rate

    Note: set the “Update period” to

    • 1000ms for 1Hz
    • 500ms for 2Hz
    • 200ms for 5Hz
    • 100ms for 10Hz


    Tips For TAU1312, support 1/2/5/10Hz in standalone mode.

    1.5 RTK mode

    1.5.1 set to RTK mode

    set DGNSS to RTK

    1.5.2 set RTK data output rate [PVT,NMEA]

    set output rate

    Note: set the “Update period” to

    • 1000ms for 1Hz
    • 500ms for 2Hz
    • 200ms for 5Hz


    Tips For TAU1312, support 1/2/5Hz in RTK mode.

    1.5.3 RTK base station

    set evk as a base staion, you need set the evk to output RTCM data:

    • Type 1005 (base station position)
    • Type 1077/1087/1097/1107/1117/1127 (raw data, MSM7)


    Tips To reduce the data payload, you could set the RTCM data from MSM7 to MSM4.

    i. set output rate to 1Hz

    set output rate

    ii. set NMEA output off

    NMEA off

    iii. set RTCM output on

    RTCM on

    iv. set fixed position for base station

    set fixed position for base staion

    • CFG-FIXEDECEF
    • If you have the known position for base station, please input the three value XYZ.
    • Otherwise, press “GetNow” to fill the XYZ field
    • Then Press “Send” button

    After above operation, you will see the following 1005 with the fixed base position.

    Check RTCM type 1005 with the fixed pos

    1.6 Save config

    Tips Save config to keep the configuration available in the next power boot.

    Save config

    Press “Send” button to save it. Sometimes if the data update rate is too high, you need press button several times.

    2. Test EVK-TAU1312 with 3rd party utilities

    • str2str, a powerful utility for stream application
    • rtkplot, a powerful plot utility

    above two utilities is the part of the famous RTKLIB. if you want the full experience test, please download RTKLIB from rtklib official website
