This paper quantifies the relationship between forward scattered L‐band Global Navigation
Satellite System (GNSS) signals, recorded by the Cyclone Global Navigation Satellite …

In traditional GNSS applications, signals arriving at a receiver's antenna from nearby
reflecting surfaces (multipath) interfere with the signals received directly from the satellites …

The ability of spaceborne Global Navigation Satellite System (GNSS) bistatic radar receivers
to sense changes in soil moisture is investigated using observations from the low Earth …

The Global Positioning System (GPS) is a navigation system based on satellite technology.
Its fundamental technique involves measuring the ranges between the receiver and a few …

Launched on 5 June 2019, the BuFeng-1 A/B twin satellites were part of the first Chinese
global navigation satellite system reflectometry (GNSS-R) satellite mission. In this letter, a …

Ground-reflected global positioning system signals measured by a geodetic-quality GPS
system can be used to infer temporal changes in near-surface soil moisture for the area …

The calibration algorithm used by the Cyclone Global Navigation Satellite System
(CYGNSS) mission to produce version 2.1 of its Level 1 (L1) science data products is …

We present the first spaceborne observation of a Global Positioning System (GPS) signal
reflected from the Earth's surface, specifically from the Pacific Ocean. This result is scaled to …

This paper presents the fundamental characteristics of bistatic altimetry performed using the
Global Positioning System (GPS) signal scattered off the ocean surface and collected by a …

This paper develops and characterizes the algorithms used to generate the Level 1 (L1)
