Latest Patents

Bergesen holds a patent titled "Real time position correction to ground generated spacecraft ephemeris." This invention implements a reference trajectory management module, an error estimation module, a parameter calculation module, and a position information management module. The reference trajectory management module accesses reference trajectory data, such as ground-generated ephemeris data, which is uplinked to a spacecraft through a communications unit. The position information management module interprets position information, such as Global Positioning System (GPS) measurement data, to provide measured spacecraft positions. The parameter calculation module calculates spacecraft position and velocity from the reference trajectory data. The error estimation module compares the measured and calculated positions to provide a position difference, smoothes the position difference to filter anomalous data, and provides a correction term for the determination of corrected spacecraft orbital parameters.
