It provides time accurate to 1 x 10E-6 seconds.The GPS receiver receives time from the GPS satellite constellation which surrounds the earth. The receiver is standard on all of our Howard and Seth Thomas Street Clocks (pre-mounted on the top of the clock). It must be located with a partial view of the sky. The receiver is provided with a 150′ (45 meter) cable.
