\section{Detailed Project Descriptions}
\headerwithlabel{spacetime}{(work in progress) \href{https://philiplinden.github.io/spacetime/}{philiplinden.github.io/spacetime}}{Personal, 2024}
A simulation of heterogeneous networked clocks in cislunar space, built in Rust on the Bevy game engine. This project aims to use agent-based modeling and simulations to explore how network topology and time synchronization evolve in a growing lunar ecosystem. Modeling how the approach may be used in practice and at scale informs decisions about how to architect a robust cislunar PNT system that scales with the population.

{\bf Graduate Paper}
\headerwithlabel{Cislunar Open Clock Synchronization System (CLOCSS)}{\href{https://www.youtube.com/watch?v=cd8hiubLy48}{presentation}}{MoonDAO, 2023}
{\it DARPA LunA-10 Proposal (Shortlisted)}
Developed a concept for a decentralized approach to lunar infrastructure. Authored manuscript and presentation materials submitted to DARPA's \href{https://www.darpa.mil/news-events/2023-08-15}{LunA-10} capability study.

\headerwithlabel{Possibilities for a Local Lunar Time Standard}{\href{https://www.openlunar.org/research/possibilities-for-a-local-lunar-time-standard}{white paper}}{Open Lunar Fellowship, 2023}
Authored a white paper that explores the characteristics of a common reference timing signal to serve future lunar operations. The goal was to identify a low-cost, transparent approach to the development of a Local Lunar Time Standard.

\headerwithlabel{On-Orbit Demonstrations of Proactive Tasking of Glint Imagery}{}
{IEEE Aerospace Conference, 2023}
{\it Awarded Best Paper in Track (Track 12)} \href{https://doi.org/10.1109/AERO55745.2023.10115608}{doi:10.1109/AERO55745.2023.10115608} \\
Formalized a methodology to predict future glint windows over a specific region. Studied various tasking approaches that described the satellite's actions during these windows to autonomously acquire glint captures. These actions were then demonstrated by orbiting satellites, and their captures were then analyzed.

\headerwithlabel{Automatic Optical Image Stabilization System Calibration}
{\href{https://digitalcommons.usu.edu/smallsat/2021/all2021/189/}{SSC21-VIII-05}}
{Small Satellite Conference, 2021}
Developed and executed an on-orbit calibration campaign. Automated on-orbit procedures and analyses were used for calibration and validation of an optical image stabilization (OIS) system across a fleet of 19 satellites. OIS actuation settings were configured for each image capture through automated optimization procedures.

\headerwithlabel{High Altitude Balloon Autonomous Altitude Control
System}{\href{https://brickworks.github.io/Nucleus/pdr_altitudecontrol/}{brickworks.github.io/Nucleus}}{Personal, 2020}
Designed a control system for a high altitude balloon (HAB)
to maintain a target altitude by venting gas from the balloon and dropping
ballast mass in flight. I modeled passive flight dynamics of a HAB in MATLAB,
Simulink, and Python. I developed a state machine and control system in
Simulink and used the model to tune a PID controller. I then derived a
state-space model, Kalman filter, and LQR controller from scratch to achieve
better performance.

Contributed to a proposal for a Probe Class (\textasciitilde\$850M) NASA mission
for a 1.5 meter space telescope intended to observe near-infrared light from the
early universe. Compiled financial, mass, and power budgets for the optics,
instruments, cryocooler \& spacecraft. Defined system-level design, generated
representative CAD models and figures of the spacecraft. This mission was

Developed the concept, system-level design, and nozzle design for a small scale
arcjet thruster demonstration. Worked in a multidisciplinary team of mechanical
and electrical engineers. Responsible for communication between the team and the
customer (RIT Space Exploration). Designed and performed CFD analysis on the
thruster nozzle.

\headerwithlabel{Optical Image Stabilization System On-Orbit Calibration}
{\href{https://digitalcommons.usu.edu/smallsat/2021/all2021/189/}{Small Satellite Conference 2021}}
{\bf Publication}
Led a small team to calibrate SkySat Optical Image Stabilization (OIS) System,
and overhauled the calibration process into an automated procedure. The
automated procedure improved calibration from a manual effort requiring weeks
of effort by a subject matter expert, to a code-assisted workflow that may be
completed by any flight operator in a matter of hours. Wrote a conference paper
and technical presentation describing key concepts of the technology, an
overview of the calibration approach, and key results of the effort. The
calibrated OIS system improves SNR and constrains motion blur to less than 1
pixel while also allowing faster scan rates and HDR captures.

\headerwithlabel{SkySat Payload Commissioning \& Recalibration}{Planet}{}
Conducted on-orbit calibration of payload subsystems. I developed new
procedures and Python scripts to automate calibration workflows and commission
the payloads of eight newly launched SkySats and recalibrate payloads of the
rest of the 21-satellite fleet.

Python. I developed a state machine and control system in Simulink and used the

image processing with a Raspberry Pi 3, Python 3 and OpenCV 3.3 to mask RGB
images of the Earth and attempts to mask areas of vegetation using colorspace
transformations. WUAP flew as a payload on RIT Space Exploration's HAB4 high

telescope, and mechanical supports in Solidworks 2015. I was the systems
engineer for payload integration with a Black Brant IX at NASA Wallops Flight
Facility.
