Photogrammetric application for high precision positioning of drones
The experiments to measure the cosmic microwave background (CMB) radiation requiere high precision polarized calibrators. For this, our group is developing a drone based calibrator able to provide a polarized reference signal on the sky, requiring a high precision metrology system able to provide an extremely accurate position and aim of the drone while flying. Our system is based on photogrammetry (patent pending) and can monitor the polarization angle of the source with better than 0.1 degrees of absolute accuracy. In this IPRE the student will contribute to develop this metrology system, performing field tests with the drone, running experimental data analysis, developing of specialized photogrammetry software, and, if possible, can even participate in real site tests at the astronomical sites of northern Chile.

Modeling of the atmospheric signal and other contaminants in cosmological data
The measurements of the cosmic microwave background radiation done from the ground suffer from atmospheric contamination, as well as other contaminants. This justifies the development of new models to identify and treat these contaminants, aiming to produce clean maps of the background signal. Our group is an active collaborator of several CMB experiments installed in Chile, contributing among other things to the analysis and reduction of raw data, including the modeling of contamination and systematic effects contained in the data. In this IPRE the student will develop computational and mathematical methods to model and extract the atmospheric signal from real raw data obtained by the ACT telescope. His/her results will be potentially implemented in the real pipeline for the production of better CMB maps.
