GPS positioning is what causes the slow GPS positioning is generally slow because of a hardware problem, determine GPS positioning time is that it's time to start positioning time is the time to restart GPS receiver receives location determines the time required for now. For 20-channel receiver, if you locate near the last location of the cold start positioning time is usually 3 to 5 minutes, the hot start of 15 to 30 seconds. Cold start initial use; battery depletion resulting in loss of information ephemeris. GPS can not locate what is the reason the general case of GPS signal vulnerable buildings and metal barrier, so the use of GPS to be outdoors.

GPS positioning is not exactly what the reasons 1, GPS positioning system, regardless of vehicle positioning system, or personnel positioning system. Both civilian and military sub-two kinds. Because the GPS satellite positioning system used in the United States on military and civilian motorcycle gps price differential signal, GPS positioning system we contacted all of this is the root of civilian positioning error. 2, the map is accurate and detailed GPS positioning system is accurate also factors. 3, misunderstanding, positioning and positioning GPS positioning system on the electronic map in reality there is a gap in the electronic map is a coordinate point as a reference position, but in reality the coordinate points may be a building or other object. 4, GPS positioning system itself quality problems, incorrect installation may cause misalignment.
