>>382108>GLONASS ?is a space-based satellite navigation system operated by the Russian Aerospace Defence Forces. It provides an alternative to Global Positioning System (GPS).
At peak efficiency, the standard-precision signal offers horizontal positioning accuracy within 5–10 meters, vertical positioning within 15 meters, a velocity vector measuring within 10 cm/s, and timing within 200 ns, all based on measurements from four first-generation satellites simultaneously.
battery life on gps devices can be better, since they don’t use a “super duper ultra bright, mega colorful, 720p HD screen”
