GLONASS is pretty underrated. For example, it powers a whole bunch of vital farm equipment in the US.

Although the Russian air force planes with a Garmin taped to the control panel may indicate otherwise on that technology....

I get it, reddit is a fun place to beat up on the Ruskies. But the usage of a Garmin doesn't mean GLONASS is bad.

GPS and GLONASS use different frequencies and redundant signaling systems is common in aviation.

And Garmin actually works with both for a more accurate location:

It could also be a way to better resist to jamming or (government mandated) data pollution by matching the data from the two receivers for significant differences. I'm 100% pro-Ukraine but that looks a smart move to me.
