Radio Trigger Module
RTM3 - Seismic Source Co. (SSC)
The Remote Trigger Module 3, or RTM3 3, is a new generation of impact trigger device. It is designed to time synchronize a single seismic source unit with multiple seismic recorders. It can also be used to synchronize multiple seismic recorders. The RTM3 units use an internal high accuracy oscillator that is synchronized to GPS timing information. Each RTM3 unit requires an external GPS receiver with valid satellite information to synchronize the internal clock. Once the internal clock is synchronized the RTM3 can be used without any GPS signal for up to 10 minutes.
