A Statistically Optimized Star Camera Fusion Approach for the Attitude Determination of Low-Low Satellite-to-Satellite Tracking Mission

Abstract: Precise attitude determination is essential for orbit determination and time-variable gravity field recovery from low-low Satellite-to-Satellite Tracking (ll-SST) missions, e.g., GRACE and ...

I ditched Google Maps for a free alternative that doesn't track me (or drain my phone battery)

CoMaps is community-driven, open-source, transparent, and the developers aren't concerned with making a profit. The app is fairly new (just hitting Google Play Store and the Apple App Store around ...
