Data flow from Reftek recorders to seedlink server is working

The first major task of the TuSeisNet near real-time data flow reorganization is working. The data finds its way from the Reftek recorders to a seedlink server.

First permanent installation

Last week we installed two Ruwai data recorders at two field sites. One in a gallery at the foot of mount Hoher Sonnblick and another one at the top of mount Kitzsteinhorn. I’m curious if the data recorders behave as reliable as they did in the lab.

GPS timestamping works

One very important feature of a seismograph is the timestamping of the sampled data to an absolute time reference. The most important a global time reference is the GPS time and I'm using it to correctly timestamp the samples of the Ruwai data recorder. A test with another seismic data recorder of a different type shows that it is working.

Learning by doing

I started with the first small series of GPS Timing Shield PCBs. After resolving some problems it worked fine.

DIY assembly

I started with the assembly of a small series of Ruwai. I chose the Power Supply shield to start because it doesn't contain too many SMD components. Perfect to start learning.
