Aided GPS/GLONASS Navigation in Urban Environment - (PPT)

摘要

Different GNSS combinations are tested in single point with LS and KF estimators. Including GLONASS measurements in GNSS positioning provides improvements in terms of solution availability and accuracy (above all LS). Applying aid on altitude, performances are improved for all tested configuration (Availability & Accuracy). The Kalman Filter has the advantage (on LS) of a continuous solution; the vertical component is better estimated (thanks to process model suitable for land navigation). Applying aid on inter-system bias yields benefits only in terms of availability.
