Power Consumption by GPS Receivers


Note: Hours of Operation are based on theoretical battery specifications for new batteries. Expect older batteries have reduced hours of operation and always have extra batteries on hand to replace dead or malfunctioning batteries.

Voltage (V) V=sum(v) v=v=v      
Resistance (R) R=sum(r) 1/R=(1/r)+(1/r)+(1/r)      
Current (I) I=I=I I=i+i+i      
           
Voltage=Current*Resistance [V=I*R]          
Power=Current*Voltage [P=I*V]
