GMTANeither the Standard or the 4k use GLONASS. At this time only the Advanced & Pro have that additional feature.
Just ordered a advance today. Thanks for the info.No. You'll need to get the P3A/P3P if you want GLONASS too.
Honestly I don't see much difference in satellite count here in the Midwest between my P3P and my other phantoms without GLONASS.
