Software-Defined Radio Direct Correlation GNSS Reflectometry by Means of GLONASS

Dynamically Reconfigurable Software Defined Radio for Gnss Applications

Historically, the military has used special purpose Global Positioning System (GPS) radios for radio navigation. This has the disadvantage of locking users into fixed technology solutions designed to meet a fixed set of requirements. Software Defined Radios (SDR) have the advantage of being able to easily adapt to provide new capabilities using current generation technology. Continued improveme...

Multicore Software-Defined Radio Architecture for GNSS Receiver Signal Processing

We describe a multicore Software-Defined Radio (SDR) architecture for Global Navigation Satellite System (GNSS) receiver implementation. A GNSS receiver picks up very low power signals from multiple satellites and then uses dedicated processing to demodulate and measure the exact timing of these signals from which the user’s position, velocity, and time (PVT) can be estimated. Three GNSS SDR ar...

GLONASS-R: GNSS reflectometry with an FDMA based satellite navigation system

This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the signals can become a valuable data source, from which geophysical properties can be deduced. This approach, called GNSS-Reflectometry (GNSS-R), can be used to develop i...

A software defined radio platform with direct conversion: SOPRANO

ilktract-In this paper, a new software defined radio plat-forim with multiport-based direct conversion is proposed, named SOPRANO (Software Programmable and Hardware Eeconfigurable Architecture for Eetwgrk). The main features of SOPRANO are a high-level design methodology for digital circuits, a new mixer-less direct conversion method, and software algorithms for multi-band and multi-mode opera...
