Claim Text:
1. A method for measuring a parameter of an alternating current power grid with a measuring system that includes an antenna exposed to the sky, a signal receiver coupled to the antenna, and a measuring device coupled to the signal receiver via a cable, the method comprising: receiving a first signal at the antenna; transmitting the first signal to the signal receiver; generating a second signal at the signal receiver; generating a third signal based on the second signal and electrically isolated from the second signal; transmitting the third signal in the cable toward the measuring device; generating a fourth signal based on the third signal and electrically isolated from the third signal; transmitting the fourth signal to the measuring device; calibrating the fourth signal by subtracting a delay constant from the fourth signal, wherein the delay constant approximates the delay between receipt of the first signal at the antenna and a receipt of the fourth signal at the measuring device; and measuring a parameter on the alternating current power grid relative to the calibrated fourth signal.
