Time Stamp Recorder 4

Overview

The Time Stamp Recorder 4, or TSR 4, is a compact autonomous trigger timing system designed to record precise hit times and GPS positions for impact seismic sources. Each trigger event is stored on a removable ruggedized memory plug and later combined with autonomous nodal recording data to create shot records.

The TSR 4 is ideal for modern autonomous seismic acquisition systems where precise source timing and accurate GPS positioning are required without continuous radio communication. Internal GPS timing, integrated Wi-Fi, removable storage, and optional Android navigation support make the TSR 4 a lightweight and highly portable acquisition solution.

When paired with the optional Navigation App, operators can navigate directly to shot points, view shot status information in real time, log comments during acquisition, and automatically generate observer logs containing line numbers, station numbers, shot times, and GPS source locations.
