Looks like we'll see an improvement on gps accuracy in phones and u-blox gps systems in the coming year. The Ruskies are updating the firmware on their GLONASS gps birds to reduce tropospheric and ionospheric interference by 70 to 80%. Overall positional accuracy will be improved. sputniknews.com/science/201712241060285811-glonass-new-firmware/
Not sure if it will be of any benefit to GW-60 GPS watches we use, can't find any mention of Locosys using GLONASS tracking on the GW-60.
Read article online that Russian system not as accurate as GPS. Own measurement seemed to confirm this. Maybe Russians are upgrading to match other providers accuracy.
