“…In [38,39], the piecewise constant system (PWCS) method is used to analyse the observability of a time variant system. The global observability is applied to analyse navigation states' observability of integrated navigation systems [40] and non-holonomic constraints [41,42]. According to [42,43] and [44], under different maneuvering, unobservable states will become observable.…”

“…The global observability is applied to analyse navigation states' observability of integrated navigation systems [40] and non-holonomic constraints [41,42]. According to [42,43] and [44], under different maneuvering, unobservable states will become observable. The researchers introduce the concept of degree of observability, which reflects the effect of maneuvering to state estimation in [45][46][47].…”

“…However, GNSS faces problems such as signal blockage and multipath in urban areas and other GNSS-challenging environments. In these cases, GNSS/INS (inertial navigation system) integrated systems are usually used for navigation applications [3][4][5]. However, GNSS/INS integrated systems cannot work well for pedestrian navigation in deep indoor environments where GNSS is totally unavailable.…”

“…Calibration is a useful way to remove many deterministic sensor errors and improve sensor-based navigation [10]; however, MEMS inertial sensors suffer from significant run-to-run biases and thermal drifts [11]. Especially, the heading error will grow when there is no aiding information [12]. Magnetometers can assist the heading estimation by sensing the geomagnetic field [13].…”
