Get your first position fix using GNSS-SDR and a file containing raw signal samples.

GNSS-SDR is an open-source project that implements a global navigation satellite system software-defined receiver in C++. With GNSS-SDR, users can build a GNSS software receiver …

Then, GNSS-SDR takes care of all the digital signal processing, performing signal acquisition and tracking of the available satellite signals, decoding the navigation message, and computing the observables needed by positioning algorithms, which ultimately compute the navigation solution.

You will need Xcode and a software package manager such as Macports (there is a gnss-sdr port that will do all the work for you) or Homebrew. Microsoft Windows: At this time of writing, GNSS-SDR cannot be built natively on Microsoft Windows.

By adopting GNU Radio’s signal processing framework, GNSS-SDR bases its software architecture in a well-established, highly-efficient design and an extensively proven …

Tutorials In addition, there is a set of tutorials providing more information in particular topics or examples of use:Organization of the documentation

GNSS-SDR and its software dependencies can all be installed either by downloading their source code, building and installing them in your system, or by installing the corresponding software package.

This page describes examples of hardware setups, software configurations, and general tips for obtaining position fixes (and a collection of side data, delivered in standard formats) with GNSS-SDR.

2020年8月7日 · This article introduces the operation details and some performance measurements regarding this GNSS-SDR feature. The GNSS-SDR support for Realtek RTL2832U dongles makes use of the OsmoSDR GNU Radio source block and driver.

2025年2月19日 · The design of a GNSS software-defined receiver needs to resolve some design forces that could appear as antithetical, (e.g., portability vs. efficiency, openness vs. marketable product), and a “sweet spot” must be identified according to the targeted user and application.
