The utility model provides a high-precision positioning
Bluetooth watch based on a dual-frequency GPS 8, and the watch comprises a housing, the interior of the housing is fixedly provided with a holder, the interior of the holder is movably connected with a
lithium battery in a clamping manner, one side of the
lithium battery is provided with a control mainboard, the control mainboard is connected with the holder in a clamping manner, and the bottom of the control mainboard is provided with a
wireless charging module. An
electric control button is arranged in the middle of the upper surface of the control mainboard, and a GPS module is welded to one side of the control mainboard. Through the arrangement of the
Bluetooth transceiver, the control
chip and the GPS module, when the watch carries out positioning operation,
information transmission with multiple satellites can be formed at the same time, and the L1 + L5
wave band of each
satellite is received; therefore, the multi-
signal information overlapping positioning operation is completed, and the problems that in the prior art, GPS single-frequency positioning is adopted mostly, so that positioning updating is very easy to occur slowly on a crowded road section or a tunnel mountain road with poor signals, judgment of a user on the position of the user is affected, and then the user misses an intersection are solved.
