Mezintel Gamma continuously sends out data to depth tracking EDR providers such as Pason and RigSense (NOV).
On a regular basis, about every 5 seconds, WITS data packets are sent out as several lines of plain text (ASCII) that are usually comprised of Toolface, Surveys, and Gamma data.
As of version 22.00.031 [1], you have more control over the structure of the data packet.
