Visual–inertial odometry (VIO) is known to suffer from drifting, especially over long-term runs. In this article, we present GVINS, a nonlinear optimization-based system that tightly fuses global navigation satellite (GNSS) raw measurements with visual and inertial information for real-time drift-free stateestimation. Our aims provide accurate six-degree-of-freedom estimation under complex indo...
Nature is observed at all scales; with multiscale modeling, scientists bring together several scales for a holistic analysis of a phenomenon. The models on these different scales may require significant but also heterogeneous computational resources, creating the need for distributed multiscale computing. A particularly demanding type of multiscale models, tightly coupled, brings with it a numb...
Nonlinear Observer for Tightly Coupled Integrated Inertial Navigation Aided by RTK-GNSS Measurements
To overcome the limited payload dedicated to onboard antennas for CubeSat/SmallSat applications, this paper presents a novel, foldable, dual-polarized Tightly Coupled Dipole Array (TCDA). In comparison previous vertical feeds used TCDAs, array integrates planar microstrip balun feed enable foldability. The proposed attains 5.4:1 (0.6-3.20 GHz) impedance bandwidth with VSWR < 3 at broadside and ...
