Hi, I’m Juno Woods, PhD.

I do spacecraft navigation (state estimation), and mission design, with a focus on lunar missions, and dabble in space settlement policy. I believe firmly that we cannot solve our environmental problems without moving heavy industry into space, which requires a sustained presence on the Moon.

I perform engineering work on a contract basis. Please do reach out if you’re interested in hiring Translunar LLC. My CV, which includes my email address, is linked in the upper right-hand corner.

Briefly, here are some of the services I provide:

  • Design and derive an extended Kalman filter, including measurement models for sensors.
  • Spec out an inertial measurement unit (IMU).
  • Conduct an observability analysis.
  • Use a linear covariance analysis to specify navigation requirements, such as how often your sensors need to update along a given trajectory.
  • Design or optimize a trajectory.
  • Determine sensor location and mount angles and design a mission attitude timeline.
  • Provide delta-v estimates and other types of error budgets.
  • Size a reaction control system and analyze controllability using candidate optimal groups.
  • Design an eigenaxis controller.
  • Help you with approaching (berthing or docking) or departing the International Space Station.
  • Various relative navigation problems, especially using LIDAR or cameras.
  • Implement terrain-relative navigation designs.
  • Select ground station locations for the best possible orbit determination solutions.
  • Design a batch least squares estimator for incorporating two-way radiometric measurements.
  • Implement guidance algorithms for planetary landing.
  • Write hardware-in-the-loop simulations in C, C++, and Python.
  • Write proposals, business plans, or grant applications.

I do not work on any weapons systems.

I’m non-binary and my pronouns are they/them. I find that, in the aerospace industry, folks don’t talk about gender or pronouns much. If you have questions, MyPronouns.org is a useful resource — or you can just ask me.
