The Mills Cross project was the first major project that I worked on at the Remote Sensing Center. This project was a ground radar built to measure ice thickness. We built a 20m x 18m cross out of many layers of fiberglass and insulation foam, which encased radar antenna elements. The project was flown to Northern Greenland at the EastGrip camp in August of 2018, and was operated by one of my colleges, Chris Simpson. Below, check out some images of our project from fabrication to deployment!

We used cinder blocks here to provide weight on a wire bulkhead while it was curing to the panels

These green fiberglass rails allow us to mount the panels on stands, and to connect them together on the sled
