Localization package (This package is still under development)

This package seeks to provide navigation solution in diverse scenarios using different sensors, with:

Expected Capabilities (under development)

evaluation of algorithm: filtering (eg.EKF) and smoothing (eg. factor graph)

Using

GNSS(GPS/BeiDou in Asian area): raw measurements is better (robust GNSS).
INS: using Xsens MTi 10. state-of-the-art pre-integration is applied.
LiDAR odometry: using LiDAR odometry by matching two frame of point clouds.
LiDAR matching: using LiDAR matching between map and real-time point clouds.

Package description

amsi- adaptive multi-sensor integration package
nlosExclusion- GNSS NLOS exclusion package (under development)
rtklibros- rtklib in ros package rtklib
Mapping- LiDAR mapping and its integration with GNSS (in local frame) (SLAM)

Currently support

loosely coupled GNSS/INS integration using EKF at here.
tightly coupled GNSS/INS integration using EKF at here.
loosely coupled GNSS/INS integration using factor graph at here.
tightly coupled GNSS/INS integration using factor graph at here (to be developed).

How to use this for your data

The data for public will be opened soon,
