A Multi-Global Navigation Satellite System (GNSS) Time Transfer Method with Federated Kalman Filter (FKF)

open access: yesSensors, 2023
Relative to single Global Navigation Satellite System (GNSS) measurements, i.e., the measurements from a single GNSS system, a single GNSS code, and a single GNSS receiver, multi-GNSS measurements for time transfer could improve reliability and provide ...

A prototype for a Multi-GNSS orbit combination

open access: yes2020 European Navigation Conference (ENC), 2020
Since 1994, the International GNSS Service (IGS) provides a combination of orbit and clock offset products from its different Analysis Centers. These products are used as input by many software for countless scientific and/or operational applications. They can also be used as an independent reference for benchmark experiments.

Posicionamento multi-GNSS

open access: yesRevista Brasileira de Cartografia, 2020
GNSS (Global Navigation Satellite Systems) have gained a lot of visibility in the last two decades, being currently applied in several activities that go far beyond navigation positioning, some of them requiring high precision (centimeter to millimeter), such as structural monitoring and precision agriculture.

Enhanced GNSS Reliability on High-Dynamic Platforms: A Comparative Study of Multi-Frequency, Multi-Constellation Signals in Jamming Environments

open access: yesSensors, 2023
The global navigation satellite system (GNSS) signals are vulnerable to disruption sources, such as signal jamming. This, in turn, can cause severe degradation or discontinuities of the GNSS-based position, navigation, and timing services.

A Novel Method to Estimate Multi-GNSS Differential Code Bias without Using Ionospheric Function Model and Global Ionosphere Map

open access: yesRemote Sensing, 2022
Global navigation satellite system (GNSS) differential code bias (DCB) is one of main errors in ionospheric modeling and applications. Accurate estimation of multiple types of GNSS DCBs is important for GNSS positioning, navigation, and timing, as well ...
