This paper examines the performance of the Galileo Open Service Navigation Message Authentication (OSNMA) in various scenarios, elucidating its logic and workflow and revealing its functionality and intended purpose.
An easy-to-read primer on GNSS jamming, spoofing and mitigation with illustrations and in-depth sidebars that explain key terminology to boost your knowledge.
A key requirement of autonomous vehicle applications is a reliable, accurate, and robust positioning (aka) localization solution. Key navigation, planning and decision operations cannot happen without dependable positioning.
The following is from “TerraStar X Precise Positioning Enables Autonomous Applications”, presented by Sara Masterson at Multi GNSS Asia, 2018.
This paper presents the first results of precise point positioning (PPP) with RTK From the Sky technology: immediate, globally available, centimeter-level accuracy.
This paper describes a method for mapping interference by using a model of power loss over distance to create a map of the likelihood of the position of the interferer.
Scanning LiDAR sensors have become a standard component in most mobile mapping systems, and they provide an impressive level of detail in 3-dimensions...
GNSS interferers come in many forms and classifications. Some are intentional, purpose built in-band jammers, but many are unintentional, originating from sources such as radio, TV, wireless communication and radars...
The antenna is the first component in a positioning system, which processes the GNSS and correction signals received from multiple satellites. The precision of a position is strongly related to the performance of the GNSS antenna used...
It can be a difficult task trying to determine what kind of GNSS/INS solution will meet the needs of a specific application...
High-quality continuous carrier phase can be used to estimate vehicle motion at the centimetre level over short periods of time even when the absolute position accuracy is at the meter level...
GL1DE provides a relative pseudorange / delta-phase filter enhancement for the NovAtel OEMV firmware. Three sets of GL1DE test results are presented.
