| 摘要： | The objective of the work described was to build a nanosat as part for the UNP-6 competition cycle to demonstrate the use of the Global Positioning System (GPS) as passive bistatic radar for on-orbit relative navigation, proximity detection and remote sensing. This was the University of Minnesota s entry into the UNP-6. This bistatic radar will use GPS signals reflected or re-radiated from objects on orbit to detect, localize and perhaps characterize or image them. At a minimum, reflected GPS signals can be used to provide a relative navigation measurement between spacecraft (range and velocity), allowing for a passive sensor with little additional mass and no extra power. This is particularly useful when navigating relative to non- cooperative targets (e.g, during operation for servicing malfunctioning satellites) where traditional carrier phase differential GPS techniques which rely on GPS measurement data exchange between vehicles cannot be used. |
