Graphing a Way out of Multipath: Robust Navigation for Autonomous Vehicles and Robots

A factor-graph optimization-based GNSS positioning method uses GNSS pseudorange and Doppler observations to estimate position, velocity, and receiver clock biases. Added constraints on past and current graph nodes of the graph using time-difference observations of the GNSS carrier phase improve the accuracy, and a robust optimization method excludes multipath outliers. Experimental results reduce horizontal positioning error from 5 to 10 meters to 1.37 meters.

Q: What is the future of autonomous vehicles?

The concept of autonomous driving has generated a lot of interest and attention in the past decades as it is believed to provide numerous benefits for individuals and society: increased road safety, reduced traffic congestion, accidents and death, and saving time and pollution on commuting. There is a lot of ongoing work on this topic, much research and many experiments have been conducted on how to make cars learn the environment, make human-like decisions and drive on their own.

Multiple Imaging Radars Integrate with INS/GNSS via AUTO Software Reliable and Accurate Positioning for Autonomous Vehicles and Robots

Difficult GNSS environments and adverse weather conditions require a fusion of many sensors to maintain lane-level accuracy for autonomous platforms, without incurring high costs that would inhibit widespread adoption. Radars are an attractive option in a multi-sensor integration scheme due to being robust to adverse weather and insensitive to lighting variations.

Surveyors’ Dreams that Changed the World: A Personal Recollection

By Miguel Amor, Chief Marketing Officer
Hexagon’s Autonomy & Positioning division

I had my first interaction with a geodetic GPS receiver in the early ’90s. In my freshman year of college, a professor demonstrated how to use two single-frequency receivers to achieve centimeter accuracy for post-processing observations. I didn’t know at the time that I would spend the next 30 years deeply involved in and contributing to this innovative positioning technology.

Alternative PNT Companies Partner

Locata Corporation and Ursa Navigation Solutions, Inc. (UrsaNav) announced a technology partnership aimed at providing resilient PNT solutions to national governmental and commercial interests globally. Combining Locata’s high-accuracy local-area and UrsaNav’s very wide-area PNT produces a solution which lessens dependency on easily disrupted and increasingly vulnerable space-based signals, according to the two.

Swift Navigation Pairs with STMicro’s New Triple-Band Chip

Swift Navigation announced its support of the new STMicroelectronics Teseo V. The Teseo V family is a single-chip GNSS triple-frequency device for automotive use. Swift’s team has been working with ST to ensure the optimization of Swift’s precise positioning solution—comprised of the Starling positioning engine and Skylark precise positioning service—when paired with the STA8135GA Teseo V, the first single-chip triple-band GNSS IC (Integrated Circuit).
