“…b) PDR trajectory in the third floor of the building above (an ideal floor for HDE navigation). In green color, the INS-based IEZ method (no magnetometers) [4]. The HDE solution ( =45 o ) is represented in magenta color, with black circles at the detected steps where the HDE correction is performed.…”

“…Each measurement contains the horizontal Yaw angle of the sensor's X-axis with respect to the North (see Figure 5). This Yaw angle is computed from the magnetometer (Yawmag) as in [4]. Also, we have a reference Yaw angle or ground truth (Yaw ), which is real deduced automatically from our PDR algorithms with the HDE heuristic enabled in order to keep the trajectory well aligned with respect to the dominant principal directions of the building [11].…”

“…In reference [11], [12], the zero velocity intervals are determined based on the variance of accelerometer values. In reference [13], the zero velocity is determined based on norms of accelerometers and gyroscopes along with variance of accelerations. In reference [14], the zero-velocity detection problem is abstracted as a hypothesis-testing problem.…”
