A method to compute location in GNSS denied area
TLDR
The design of such a locating device which uses both data obtained from GNSS and DRM to compute the position information where GNSS signals are not available or weak is discussed.Abstract:
This paper discusses a method to compute the location of the receiver in the area where the signal from the Global Navigation Satellite System (GNSS) such as GPS and GLONASS does not reach or weak. These areas are called GNSS denied environment. The method in takes the initial location obtained from GNSS system as seed to further compute the location of the receiver using interpolated and extrapolated positions using dead reckoning module (DRM). This paper further discusses the design of such a locating device which uses both data obtained from GNSS and DRM to compute the position information where GNSS signals are not available or weak.read more

Slam-Based Multi-Sensor Backpack Lidar Systems in Gnss-Denied Environments
TL;DR: This paper presents a multi-sensor-based backpack LiDAR system for mapping in GNSS-denied environments that solves the problem of inaccurate positioning caused by the inability to receive GNSS signals in a small-sized lidar portable device and reduces the cumulative error causing by the IMU module through the analysis of the vibration pattern.

Smartphone-based Pedestrian Dead Reckoning as an indoor positioning system
TL;DR: Pedestrian Dead Reckoning (PDR), which is a pedestrian positioning technique using the accelerometer sensor to recognize pattern of steps, is an alternative method that has advantages in terms of infrastructure-independent and the variation of walking pattern will make some difficulties for the system to detect displacement.
