-Pedestrian navigation refers to the use of Global Navigation Satellite Systems (GNSS) and other technologies to determine the location and movement of a pedestrian. It allows for the precise tracking of a pedestrian's location and movement, and it can be used for a variety of applications, such as personal navigation, emergency response, and transportation planning.

-Pedestrian navigation systems typically use a combination of GNSS, such as GPS, and other sensors, such as accelerometers, magnetometers, and barometers, to determine the location and movement of a pedestrian. The GNSS receiver receives signals from satellites in orbit and uses the information to calculate the position of the receiver. The other sensors, such as the accelerometers and magnetometers, can be used to improve the accuracy of the navigation by providing additional information on the pedestrian's movement and orientation.

-The navigation information can be displayed on a device such as a smartphone or a dedicated navigation device, and it can provide information such as the current location, direction of travel, and estimated time of arrival. Pedestrian navigation systems can also be integrated with other technologies such as digital maps and real-time traffic information to provide additional navigation capabilities.

 Pedestrian navigation can also be used to support other applications such as indoor navigation, where traditional GNSS signals may not be available, by using other sensors such as Wi-Fi, Bluetooth and ultrasonic to determine the location of the pedestrian.
