Python Implementation Of Batch Least-Squares Filter For Satellite Orbit Determination, Austin Ogle Jul 2020

Python Implementation Of Batch Least-Squares Filter For Satellite Orbit Determination, Austin Ogle

Doctoral Dissertations and Master's Theses

Accurate orbit determination techniques are fundamental to the maintenance and execution of any ongoing space-based mission. This project serves as a guide and demonstration of a batch sequential least-squares filter for Earth-orbiting satellites using exclusively open-source technologies. The target audience for this project was an academic institution aiming to keep track of an irregularly documented satellite. The observation function mimics a telescope, accepting right ascension and declination as measured values.

State propagation was handled using the Poliastro library. This package boasts FORTRANlevel speed by utilizing the DOPRI8 integrator, explicitly calling FORTRAN code. Matrix inversion was solved using the SciPy banded …


Neusch Automated Filter System: A Custom-Designed Photo-Filter Switching Apparatus For Embry-Riddle’S 1 Meter Telescope, Tyler Neusch May 2020

Neusch Automated Filter System: A Custom-Designed Photo-Filter Switching Apparatus For Embry-Riddle’S 1 Meter Telescope, Tyler Neusch

Doctoral Dissertations and Master's Theses

The one-meter telescope on the roof of Embry-Riddle’s College of Arts and Sciences building in Daytona Beach, FL is an advanced piece of technology supporting education and public outreach. One part of this telescopic system is a custom-made Cassegrain Instrument Mount. This one-of-a-kind mount allows for multiple scientific instruments to be simultaneously mounted to the telescope. However, its mechanical layout prevents the use of a traditional device known as a filter wheel.

Filter wheels store multiple photo-filters each capable of filtering out all but certain wavelengths of light for use with a CCD camera. Therefore, a filter wheel allows the …
