<= div dir=3D"auto">Hi Stefan, Andy, VLF.

A year ago, I wrote to LF group some informations about U-ce= nter, the management software by Ublox for NEO-x and LEA-x modules:

"Use "U-center" (by U-blox -=
https://www.u-blox.com= /en/product/u-center-windows) to pre-configure
the module.
= After connecting it= , it's necessary to set the navigation mode and
minimum elevation of sats (thanks to Domenico for the adv= ice).

Go to...
- Menu - View
= - Configuration vie= w

- Select item "NAV5 (Navigation 5)" (left s= ide)
- Set Dynamic Model to "= Stationary" (right side)
- Se= t Min SV Elevation to 10 degrees
-= Press Send button

- Select item "TP5 (Timepulse 5= )" (left side).
- Select Freq= uency and Duty Cycle mode (right side)
- Set Duty cycle values (50% normally)
- Set QRG values Frequency and Frequency Locked (in Hz) ...
- Press Send button

...obviously we need GPS module status ALWAYS in locked mode to obtain
a valid coherent signal...

- Select item "CFG (Configuration)" (left side)<= br style=3D"font-family:sans-serif;font-size:12.8px">- Select "Save current configuration= " (right side)
- Select all D= evices (in particular I2C-EEPROM) by keeping pressing Shift key
- Press Send button

Now t= he module is programmed."

Then, close U-center.
Now you can se= nd, via serial UBX protocol, specific commands to set your frequency (with = 1 Hz step).
The complete protocol is expl= ained in this document (have a look at page 133):
https://www.u-blo= x.com/sites/default/files/products/documents/u-blox8-M8_Rece= iverDescrProtSpec_%28UBX-13003221%29_Public.pdf

In particular, have a look also at page 221 (UBX-CFG-TP5 command= specifications).


So, have fun with= Raspberry and your new NEO GPS module.

All the best
