GLONASS position accuracy is 5-10m while GPS is 3.5-7.8m. Therefore, GPS outweighs GLONASS in accuracy as lower error numbers are better.Q:Should you use GPS with GLONASS?A:Actually only gps should do its job in case satellite reception is perfect. The combination with another system will improve accuracy when the signal gets weaker.Q:Does GPS work without an antenna?A:GPS (Global Positioning System) systems work by receiving signals from satellites. That isn't possible without an antennaQ:Where to put a GPS antenna?A:In most cases, you can mount the GPS antenna near the top of the underside of your dash (behind or above the receiver).
