Claim 0:
1. A downhole drilling characteristic measurement system for measuring a characteristic of drilling through the earth's subsurface, the downhole drilling characteristic measurement system comprising:
a downhole tool having an active measurement system, comprising a receiver, a first transmitter, and a second transmitter;
a controller in communication with the first transmitter and the second transmitter, the controller configured to control the first transmitter and the second transmitter to transmit a first transmitted signal from the first transmitter and a second transmitted signal from the second transmitter, wherein the receiver is arranged to receive a first received signal from the first transmitted signal and a second received signal from the second transmitted signal; and
a processor configured to determine 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 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.
