“…Therefore, the measured states of real (blue, up) and pseudo (green, down) sensors are coupled with each other in the redundant sensors system measurements [15, 16, 18]. The configuration number denoted by C # while sensor number denoted by S #.…”

“…The proposed approach is true for even and odd number of sensors with ultra‐care choice for the single sensor location in the case of the odd number sensors. The measurement equations of the system enclose, n , sensors [6, 16] are

“…The calibration of the navigational system and the compensation of the amount of error during navigation is one of the most urgent procedures that help stabilise the operation of the system using multiple sensors [11–14]. In [15–18], the proposed pseudo sensor enhancement method (PSEM) was introduced to achieve the optimal structural configuration of the sensors and study the prediction of the most critical sensor. Then, a specific pseudo sensor will be integrated with the critical sensor at the same arrangement position and both are working together as a unity sensor to overcome the errors that cause malfunction of the navigational system.…”
