I managed to launch GPS L1CA + Galileo E1 + BeiDou B1I

all three systems are determined by the receiver. I'm broadcasting via hackrf

May I ask if you have made any modifications to the code? I am unable to enable B1I.

Круто! спасибо большое @danusha2345

Я только что запустил код — вроде бы внесены не все изменения. @danusha2345

В функции: GpsSatPosSpeedEph(
теперь работает.

thanks！！

@danusha2345 What code are you using for transmitting IQ files over hackrf ? I tried with plutosdr but not getting any lock there and doesn't show up on spectrum analyzer. Just wanted to see if I'm doing anything wrong.

@danusha2345 Please send me the modifications of the code, the link is broken ??
also could you please give me the config you have used. ^-^

@danusha2345 thanks for the link ^_^.
sorry but, what is the config file for simulate the three gnss constellations GPS, BDS and GAL ? and if it is possible did you use more than one hackRF to transmit the 3 GNSS Constellations simultaneously.

@danusha2345 Thank you verrrrrry much.
I still have some issues with the USRP I am using B210, but I have problems like "terminate called after throwing an instance of 'uhd::usb_error' what(): Runtime Error: USBError -11: usb tx2 submit failed: LIBUSB_ERROR_NO_MEM Aborted (core dumped).
I am using a clock of 10MHz.

@danusha2345, could you please give me the config you have used for these satellites?
also, if you provide an .exe which is used for generating C8 files.

Hello, I would like to ask you how you transmit a three-mode signal. Before generating the signal: how should the central frequency be set in the json file? Additionally, I am using SDR to transmit the bin file; how should the transmission frequency be set?

[kfircohen7519]

If you can please send the configuration file to create three constellations combined?
I managed to get 3D fix with usrp and ublox only with L1CA alone and E1 alone.
By the way the link you have sent is broken
