Bosch, GM, and Swift Discuss Critical Role of Precision GNSS in AV

On April 8, 2025, Swift Navigation partnered with the Society of Automotive Analysts to host a panel on the future
of precise GNSS positioning and its role in enabling safe, scalable autonomy— and to demonstrate its power by navigating a complex test circuit using only Swift’s GNSS solution, without any visual aid.

What are the Different GNSS Correction Methods?

This blog delves into the primary GNSS correction methods-Differential GNSS (DGNSS), Satellite-Based
Augmentation Services (SBAS), Real-Time Kinematic (RTK), Precise Point Positioning (PPP), and PPP-RTK-
examining their features, advantages, limitations, and use cases.

What Is NTRIP and How Does It Work?

In this article, we delve into the critical aspects of NTRIP, including its role in GNSS correction delivery and how the technology itself works. We also highlight the advantages and challenges of using NTRIP, discuss its common applications, and provide a step-by-step guide on connecting to a NTRIP service.

Atmospheric Modeling in GNSS Corrections

This article explores the benefits and applications of atmospheric modeling, showcasing how Swift’s innovative,
future-proof approach is designed to meet the most challenging positioning needs of today and tomorrow.

What Are Reference Frames, Epochs and Coordinate Transformations In RTK?

Understanding how to align coordinates in space and time is crucial for high-precision GNSS and real-time kinematic (RTK) solutions. This article explains the core concepts of reference frames, epochs, and coordinate transformations which are essential for achieving precise positioning in GNSS applications.

How to set up the Bad Elf Flex Mini with RTK Corrections

Inaccurate GPS data can lead to costly errors in utility surveying, construction, and asset monitoring. Fortunately,
ith the Bad Elf Flex Mini, you can turn your smartphone, tablet, or laptop into a high-precision tool capable of delivering centimeter-level accuracy using RTK corrections.
