Integrated GNSS/LEO precise point positioning using factor graph optimization with heterogeneous graph-based stochastic modeling
Abstract Low Earth Orbit (LEO) satellite augmentation can improve the availability and satellite geometry of Precise Point Positioning (PPP). However, most existing Global Navigation Satellite System (GNSS)/LEO PPP methods rely on fixed stochastic models and do not fully exploit the heterogeneous characteristics of GNS...
