The University of Arizona Steward Observatory is seeking a first-year post-doc to support a research team focused on architectural and performance modeling of future cislunar satellite constellations. Through our research we intend to analyze and optimize multi-satellite constellations to maximum mission utility for space domain awareness (SDA) applications with electro-optical and passive radio-frequency (RF) sensor systems and innovative cooperative position/navigation/timing (PNT) approaches. We will use this notional architecture to  assess the various trades and opportunities for synoptic surveillance of the cislunar domain and provide foundational infrastructure for mutual self-navigation and robust communications.  Since many proposed missions such as communication relays, lunar surface GPS share the foundational form of several satellites sharing a common cislunar orbit, our tools will be extensible beyond the SDA mission which is the focus of this solicitation.
 
The post-doc position is focused on applying an integrated Model-Based Systems Engineering (MBSE) and digital engineering approach to analyze and preform trade studies using MBSE tools such as SysML, digital design tools including STK, and optical and radar sensor performance models. We strive to link formalized requirements directly to cislunar satellite constellation simulation elements, enabling automated verification throughout a digital development lifecycle. By using MATLAB and other STK-specific interoperability software within an MBSE context, this research proposes the modeling, simulation, and verification of a cislunar satellite constellation which must meet certain requirements for space domain awareness, such as sensitivity and custody. MBSE generates value as a decision-support tool for space systems deployment.

This position requires software-based model-based systems engineering experience, including SysML integration with STK and other external software and capturing mission level requirements and traceability in SysML.  Space systems modeling and simulation experience preferred. A successful candidate should have foundational familiarity with the SDA mission and a desire to apply an integrated MBSE-DE approach to bring a new comprehensive approach to mission oriented system-of-systems trade studies.

This position will work on a project that requires the incumbent to have US citizenship and eligibility for DoD security clearance.

Outstanding UA benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; UA/ASU/NAU tuition reduction for the employee and qualified family members; access to UA recreation and cultural activities; and more!
