CRA Seminar: Dr. John Christian

December 9, 2021 @ 3:00 pm - 4:00 pm

Dr. John A Christian

There will be an in-person viewing of the online seminar held in the CRA Visualization Lab (Boggs 1-44).

Title: Astrometric Methods for Star-Based Navigation
Abstract: Humans have used stars for navigation since antiquity. It should come as no surprise, therefore, that star sightings were amongst the first observables used to navigate exploration spacecraft (both crewed and robotic). Today, star observations remain central to the navigation of almost every modern spacecraft. However, as space exploration missions become more ambitious and the technologies for star-based navigation improve, we begin to run into limitations of existing methods for observing and cataloging stars. In this seminar we will discuss a variety of recent advancements at the intersection of astronomy and navigation, such as generalized astrometric calibration and velocity estimation from stellar aberration. The objective is to familiarize the CRA community with current problems at the intersection of astrophysics, astrometry, and spacecraft engineering — with the hope of fostering an a growing dialog between physics and aerospace engineering at Georgia Tech.
