Alex surveys the equipment suppplies for 15 stations, in the basement at TU-Wien

Equipment for one vehicle and about 8 stations - later supplemented with steel posts for fences.

The excavation for pit and batttery box at Laab, CBP3E, the first installation. The sensor rests ona hexagonal cement paver, 23 cm across (corner to corner).

Setting up the Solar panel frame at Laab

The solar panel is supported by 3 posts to keep it above the expected 50 cm snow depth. The large building in the background is a convent.

Pit and battery box are covered with hard boards wrapped in plastic. A fence is built to keep animals out.

Setting up in the snow and sleet at Raxendorf, CBP4C

Drainage was a problem here. With some difficulty we dug a drain and buried some irrigation pipe to drain excess water away from the sensor

With topography like this, you would expect it to be well-drained, but melting snow apparently was the source of the water.

Finally completed one very muddy installation at Raxendorf, CBP4C

The installation completed at Gross Gehrungs - also in snow, but cold and dry.

The site at Ellends, CBP3B, in well-drained sand, one of the easier installations.

A much simpler, warmer, and dryer installation at Ellends, CBP3B

Most of the equipment needed for installation of one station is laid out here for the record - add a step ladder, the fencing material and the sensor, etc.

Installation at Voestenhof, CBP4E

The solar panel set up at Voestenhof. The landowner wanted us as close to the fence as possible - even though the panel's view of the sum would be obstructed in the morning.

The installation at Siegensdorf, CBP3G, was in a nature reserve - authorised.

The GPS antenna needed to be offset from the mast on which it was mounted at Wiesmath, CBP4G.

The installation at Wiesmath, beside a demountable cabin, used for meteorological observations - battery and mains power inside.
