Measurements of atmospheric temperature, pressure, water vapor, and composition are important to users in the Earth science, defense, and intelligence communities. Nanosatellites (with mass < 10 kg, such as CubeSats) can support miniaturized instruments for atmospheric sounding and characterization. Nanosatellite constellations can improve spatial and temporal weather sensor coverage of Earth a...

In this paper, we propose an approach for constructing a multi-layer multi-orbit space information network (SIN) to provide high-speed continuous broadband connectivity missions (nanosatellite terminals) from the emerging space-based Internet providers. This notion has been motivated by rapid developments in satellite technologies terms of miniaturization and reusable rocket launch, as well inc...

Specialized drift recovery and station keeping algorithms were developed for the Canadian Advanced Nanospace eXperiments 4 and 5 (CanX-4 & CanX-5) formation flying mission (launched 30 June 2014), and successfully verified on orbit. These algorithms performed almost exactly according to predictions. The highly successful CanX4 and CanX-5 formation flying demonstration mission was completed in N...
