We have acquired a truck with aerial lift from Nor-Star (Duluth, MN). The truck will carry our Direct-Sampling Digital Radiometer (DSDR) in field experiments. For more information about our truck, contact David Boprie. |
| DSDR Mounting Structure
(Dec. 2, 1999) |
|
Rotator which holds antennas is mounted on the green unistrut. The antennas are pointed at a zenith angle of 180 degrees. The four silver zero cases on the backplanes of the antennas hold DSDR parts. The grey box in the foreground attached to the antenna that Mark is working on holds the IR and video camera. Are initial idea is to mount ACMR on the other antenna, opposite the IR and video. |
Another closer look of one antenna. Note IR/video box at center-right. |
|
In the center is the rotator. David attached a 90-degree metal plate to it so that the rotator sits in a "cradle" which is mounted on the end of the boom on the truck. You can see in the lower-left how the IR/video is attached. Imagine ACMR on the opposite side. |
Looking from the back side at the other antenna. ACMR would be mounted on this antenna. |
|
Looking down on the antenna to which ACMR would be mounted. Note that ACMR would be on the other side of this antenna, i.e. you are looking at the back side. |
A closer look at some of DSDR. This is the antenna with IR/video on the front. |
|
This is the spot where ACMR would go. The idea is that it would attach to the metal plate on at center-left where you see the tie-wrap. We can extend this metal piece if ACMR needs more room. |
Another picture of the spot for ACMR. The ruler is 31 inches long. |

Another picture of the spot for ACMR, now looking sideways. You can see 11 inches of the ruler. |
