    Effect of Space Weather on Orbit Predictions in LEO

    This whitepaper explores how variations in neutral density, driven by space weather, impact the orbit prediction of Resident Space Objects (RSOs) in Low-Earth Orbit (LEO). It evaluates the accuracy of Digantara’s proprietary orbit propagator, OrEng, through a testing framework described in the paper. Four atmospheric neutral density models - NRLMSISE-00, NRLMSIS2.0, JB2008, and WAM-IPE - were employed to assess OrEng's performance across a spectrum of Space Weather events.

    Robust Orbit Determination and Propagation Tool

    This whitepaper explores Digantara's robust pipeline for Initial Orbit Determination (IOD), Orbit Propagation (OP), and ephemeris generation. Central to these capabilities is our proprietary tool, OrEng, which plays a critical role in accurately identifying, tracking, and predicting Resident Space Objects (RSOs) in orbit. The whitepaper also presents a case study conducted at the company to assess the precision and accuracy of OrEng. For this study, the satellite Sentinel-3A (NORAD ID: 41335) was selected. The outcomes from OrEng, including state estimates and covariance, were compared with truth datasets obtained from the International Laser Ranging Service (ILRS).

    Multi-perspective Multi-modal PoL Characterization of LEO Objects

    The Pattern of Life (PoL) characterization of a satellite in Low Earth Orbit (LEO) is an intricate process demanding high fidelity data and robust data processing techniques. The solution to this complicated problem demands a methodology based on multiple perspectives and the ability to process, synthesize and correlate data from multiple sources of varying fidelity. Towards this objective, the current research proposes a dynamic and robust methodology to precisely characterize and synthesize PoL of satellites based on a multi-perspective multi-modal analysis, involving many aspects of a Space Domain Awareness (SDA) technological chain.
