Hi @koide3 , thanks for sharing your work to the community. I have test the accuracy og the ndt-omp and the conventional ndt in pcl. the ndt_omp seems to drift...

Currently, the primary method for determining the object coordinates is positioning using Global Navigation Satellite Systems (GNSS) supported by Inertial Navigation Systems (INS). The main goal of this solution is...

Hi, when I use this ublox driver to collect data from ublox EVK-M8T using the mini-USB port, I get the error as following ![error](https://user-images.githubusercontent.com/24927996/32602836-9798736c-c582-11e7-8fca-7173f64c650f.png) my launch file is : ![image](https://user-images.githubusercontent.com/24927996/32603109-7cc7f76e-c583-11e7-8920-6c57182a8dc9.png)...

Dear All Thanks for reading this pacakge. do any one successfully employ this driver in ublox M8T device? Thanks Welson

With the continuous expansion of the application field of UAV intelligent systems to GNSS-denied environments, the existing navigation system can hardly meet low cost, high precision, and high robustness in...

Monitoring [oceanographic parameters](https://www.sciencedirect.com/topics/earth-and-planetary-sciences/oceanographic-parameter) is essential for marine engineering construction, coastal safety, marine analysis, and climatic analysis. Traditionally, oceanographic parameters have been monitored using different sensors. With the development of [global...

Due to inter-frequency clock bias (IFCB), the dual-frequency precise clock products cannot be directly applied to BDS-2 triple-frequency precise point positioning (PPP). In this study, the datasets collected at 195...

Accurate rail vehicle positioning is crucial for railroad operational safety. Modern light detection and ranging (LiDAR) simultaneously localization and mapping (SLAM) systems have delivered excellent results in real-world scenarios. However,...

This paper proposes a highly accurate trajectory estimation method for outdoor mobile robots using global navigation satellite system (GNSS) time differences of carrier phase (TDCP) measurements. By using GNSS TDCP,...

Accurate positioning is one of the main components and challenges for precision forestry. This study was established to test the feasibility of a low-cost GNSS receiver, u-blox ZED-F9P, in movable...
