Ublox Max7c and the GP-02 GPRS Series GPS + BDS Compass ATGM336H work in my circuit equally well...why not the Teseo-LIV3F ?

Hello,I had recently purchased the TESEO-LIV3F GPS module from Arrow electronics.https://www.arrow.com/en/products/teseo-liv3f/stmicroelectronics I have read the datasheet carefully before purchasing this module and appeared to be very similar to the...

When I say RFI this is because the circuit the GPS is mounted to also has an Si5351 chip onboard that sends the RF to be received by radio.In the past,I had issues with 5351 and GPS interfering with each other and learned I needed to isolate this RF ...

Karim,Here is the part I can not understand.When the GPS arrived,I could clearly see it was of very good quality just in physical appearance. Like Ublox or the Generic modules,I simply placed it onto PCB and soldered it into the existing circuit.From...

So looking at my PCB schematic,I do not use this filtering at all. Also...my antenna is simply a 45mm length of wire directly connected to PCB from Pin 11.Notice I do not have Pin 6 connected...I may also connect that to VCC like figure 12 is showing...

I was looking at the datasheet and did see the additional filtering at VCC and suggest I use this for this module.The other GPS do not require these additional components and must be what is happening here as why it is not working,or not well.The cir...

Sort of a bummer...I was hoping it would work in my current circuit as is.Maybe it does not pay to get things fast...now have to wait longer for the proper GPS.This is my schematic using Ublox and generic which work perfectly fine.May be too small to...
