Neuraspace proposes a GNSS-based project to enhance satellite navigation and space traffic management. The project focuses on three features that will strengthen Neuraspace’s Space Domain Awareness platform. First, GNSS Data Cleanup will remove biases and outliers from GNSS inputs, improving reliability. Second, GNSS Orbit Determination Accuracy will deliver precise orbit and covariance outputs to support critical decision-making. Third, GNSS Orbital Phase Correction will use lightweight onboard algorithms to improve real-time autonomy. These innovations address key GNSS application gaps in satellite navigation: enhanced data quality, improved orbit prediction, and autonomous scalability for growing satellite constellations. The project aligns with ESA NAVISP Element 2 by offering a scalable, robust solution tailored to emerging small satellite operators and future space traffic management demands.
