Our agenda:
1) Homestake update
Vuk: continuing interaction with SDSTA. It looks like power will be available at all of the necessary “landings”: Yates at 1700, 4100, 4850, and Ross at 300, 800, 2000. Also, power should be available for 1700-1 seismic station, and for 4850-2,3,4. So this leaves us with battery solutions for 1700-2,3,4 and 4850-1. The 4100-2 station is unclear at this point, but it is also the lowest priority for us. One issue: fiber to 2000 via Ross has been damaged, considering rerouting via Yates - depending on this, the GPS distribution may be different.
The GPS distribution system design is near final. Liteway is making modifications to their units so that we can test them before the large order.
For network, there should be no problem at the AC-powered stations. For battery-powered stations, concerned with the power consumption due to the network switch and the media converter - if the power consumption turns out to be prohibitive, considering to store the data locally and retrieve it when the the batteries are replaced.
2) UMN test setup (Tanner)
3) Analysis of existing data
