GPS (Global Positioning System) is the position measurrment system that the U.S. control and operate. It have some posibility of
the position measurement deterioration that depends on the working GPS.
It dose not gurantee the standard,etc in this material including the case above.

Reception Unit Initialization and Operation
The GXB2000 operation is started by setting the reset input signal RESET (Pin 2) for the reception unit
initialization to high level. The timing should satisfy the conditions noted below.
During Power-on (power-on reset)
VDD = 3.0 to 3.6V, VCC = 4.5 to 5.5V, temperature = –40 to +85°C
