[time-nuts] L1 and L2 frequencies

[Martyn Smith]

Hello,

I have some questions on GPS and GNSS.

Do all the civilian GPS receivers only operate on the L1 frequency?

Are there any GPS frequency standards out there that use L1 and L2 and that can be purchased by non-military customers?

I am playing with the new Lea-M8T receiver.

How do I know what satellites are GPS, GLONASS, Galileo etc.

>From my understanding GLONASS have different SV numbers but not 100% sure.

Any help appreciated.

Regards

Martyn
