Image-assisted GNSS/INS navigation for UAV-based mobile mapping systems during GNSS outages

2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018
Nowadays, unmanned aerial vehicles (UAVs) have evolved into an alternative to traditional mapping platforms for some applications due to their flexibility and cost savings. Most UAVs, which are used as mobile mapping systems (MMS), depend on utilizing position and orientation system (POS) onboard the platform. Usually, POS consists of Global Navigation

Using UWB Aided GNSS/INS Integrated Navigation to Bridge GNSS Outages Based on Optimal Anchor Distribution Strategy

2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020
This paper investigates into the feasibility of a combined use of Ultra-wideband (UWB) and Global Navigation Satellite System (GNSS) / Inertial Navigation System (INS) for integrated navigation in GNSS challenged environments. The performance of the original integrated GNSS/INS navigation system deteriorated rapidly due to the GNSS signal outages.

Integration of GNSS and MEMS-Based Rotary INS for Bridging GNSS Outages

2015
In a GNSS/INS integrated system, the GNSS outputs, such as position and velocity, are used to estimate the INS navigation errors and inertial sensor errors and the inertial solutions are used to bridge the GNSS outages for which a good quality IMU is needed.

A Hybrid Particle Approach for GNSS Applications With Partial GPS Outages

IEEE Transactions on Instrumentation and Measurement, 2010
To provide an accurate positioning, the land vehicle navigation applications are based on global positioning system (GPS). The addition of a digital road map allows locating the vehicle continuously and helps the driver to get the best path. These systems are usually enhanced with dead reckoning sensors due to GPS outages in urban areas in particular ...
