Set Fixed LLH or ECEF

This step-by-step tutorial will let you to manually set the Longitude, Latitude, Height and Earth-Centered Earth-Fixed for the Base.
LLH: Longitude, Latitude, Height
ECEF: Earth-Centered Earth-Fixed
First, connect your GNSS device to a computer using a USB micro cable.
Now start the U-blox “u-center” software. Then on the top left corner of the screen, left-click on the reversed tiny black triangle to select the COM Port related to your GNSS device. (the COM port may differ, COM7 as shown in pictures)
Make sure the connection icon is blinking in the bottom state bar. It indicates that the serial communication between the computer and the GNSS device is working.
Next go to ‘View’ then click on “Generation 9 Configuration View
A new window showing by default “GNSS Configuration” opens.
  1. 1.
    So first, click on “Advanced Configuration” to display all the configuration registers.
  2. 2.
    Then click on the small ‘+’ on the CFG-TPMODE line
  3. 3.
    You can now have access to an expanded menu and click on CFG-TPMODE-MODE
  4. 4.
    Select “2-FIXED” in the dropdown menu
  5. 5.
    Click consecutively on RAM, BBR and Flash to write changes into RAM and both non-volatile memories (BBR and Flash)
  6. 6.
    Check the 3 corresponding commands are present in the “Ready to send” box and then click on ‘Send
LLH: Longitude, Latitude, Height set up
ECEF: Earth-Centered Earth-Fixed set up
Make sure to set up the base in Fixed Mode before setting up LLH mode
A new window showing by default “GNSS Configuration” opens.
  1. 1.
    So first, click on “Advanced Configuration” to display all the configuration registers.
  2. 2.
    Then click on the small ‘+’ on the CFG-TPMODE line
  3. 3.
    You can now have access to an expanded menu and click on CFG-TPMODE-POS_TYPE
  4. 4.
    Select “1-LLH” in the dropdown menu
  5. 5.
    Click consecutively on RAM, BBR and Flash to write changes into RAM and both non-volatile memories (BBR and Flash)
  6. 6.
    Check the 3 corresponding commands are present in the “Ready to send” box and then click on ‘Send

Setting up the Longitude and Latitude

A new window showing by default “GNSS Configuration” opens.
  1. 1.
    So first, click on “Advanced Configuration” to display all the configuration registers.
  2. 2.
    Then click on the small ‘+’ on the CFG-TPMODE line
  3. 3.
    You can now have access to an expanded menu and click on CFG-TPMODE-LAT
  4. 4.
    Enter a valid degree value within a 1e-7 scale (ex : you want 45.9635687° = you write 459635687, if you want 01.9532443° = you write 019532443)
  5. 5.
    Click consecutively on RAM, BBR and Flash to write changes into RAM and both non-volatile memories (BBR and Flash)
  6. 6.
    Check the 3 corresponding commands are present in the “Ready to send” box and then click on ‘Send
Repeat the same process to set CFG-TPMODE-LON value
Make sure to set up the base in Fixed & LLH mode before setting up LAT & LON

Setting up the Height

A new window showing by default “GNSS Configuration” opens.
  1. 1.
    So first, click on “Advanced Configuration” to display all the configuration registers.
  2. 2.
    Then click on the small ‘+’ on the CFG-TPMODE line
  3. 3.
    You can now have access to an expanded menu and click on CFG-TPMODE-HEIGHT
  4. 4.
    Enter a valid height value in cm (ex : you want 200m = you write 20’000)
  5. 5.
    Click consecutively on RAM, BBR and Flash to write changes into RAM and both non-volatile memories (BBR and Flash)
  6. 6.
    Check the 3 corresponding commands are present in the “Ready to send” box and then click on ‘Send
Make sure to set up the base in Fixed & LLH mode before setting up HEIGHT
