Claim 6:
7. A method for measuring a characteristic of drilling through the earth's subsurface, the method comprising:
conveying a downhole drilling tool into the earth's subsurface, the downhole drilling tool having an active measurement system, the active measurement system comprising a receiver, a first transmitter, and a second transmitter;
transmitting a first transmitted signal from the first transmitter;
transmitting a second transmitted signal from the second transmitter;
receiving, with the receiver, a first received signal from the first transmitted signal and a second received signal from the second transmitted signal; and
determining, with a processor, the characteristic of drilling from the first received signal and the second received signal, wherein the characteristic of drilling is indicative of at least one of a rate of penetration, a depth, a rotational velocity, an arc length, and a toolface,
wherein the downhole drilling tool is configured to rotate about a longitudinal tool axis and the first transmitter and the second transmitter are both positioned uphole relative to the receiver or the first transmitter and the second transmitter are both positioned downhole relative to the receiver along the longitudinal tool axis.
