  • Supporting an estimation of satellite locations
    Patent number: 10564292
    Abstract: An apparatus computes first locations of a satellite for several points in time based on a first set of parameters values broadcast by the satellite for a first validity period and second locations of the satellite for these points in time based on a second set of parameter values with associated second validity period. The first or second validity period is extended by an equation of motion, which includes forces acting on the satellite. The apparatus computes a value of an error component for points in time by comparing first with second locations and fits parameter values of a model to the values of the error component to obtain a model of a time-evolution of values of the error component. The apparatus provides the model of the time-evolution as a basis for a correction of locations of the satellite that are computed based on the first set of parameter values.

  • State vector estimation using a constraint derived from a map
    Patent number: 8892392
    Abstract: It is disclosed to estimate a state vector of an object, wherein the state vector comprises a state variable related to a position or an orientation of the object, based on at least one of a probability density function of the state vector truncated under consideration of a constraint for the state variable, wherein the constraint is derived from a map, and properties of the truncated probability density function.
