I am looking for someone who can design a gps tracker using gsm/gps/gprs combo module sim900a.
This gps tracker will not track continuously. It will track only on request of tracking.
This tracker will be in sleep mode all time, and wake up after periodic intervals and look for tracking request.
In sleep mode it should consume least battery in such way that it will run continuously on 1100mAh battery
for atleast one year.
for reference you can see this device.
