Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

As a GNC Intern, you will support the development of our in-house satellite, Element, by analyzing future satellite and constellation missions to drive technology roadmaps and business plans. This will be a project-based internship where you will get the opportunity to work on a space mission analysis assignment.You will work closely with CesiumAstro engineers on orbit design, mission analysis, system trades, and subsystem interactions. Interns will have the opportunity to contribute directly to CesiumAstro’s spacecraft programs through Element GNC analysis as well.

During the program, interns will present their work to peers, mentors, and Cesium executive leadership. As such, strong communication skills are essential.
