Advances in Satellite Navigation Technology Important for the Global Shipping Sector
Anti-Jamming and Anti-Spoofing Crucial to Cyber Security
BELGIUM – WORLDWIDE – Leuven headquartered Septentrio, which specialises in high-precision Global Navigation Satellite System (GNSS) positioning solutions, announced today that its receiver has successfully authenticated navigation data of the first OSNMA encrypted GNSS satellite signal. OSNMA (Open Service Navigation Message Authentication) offers end-to-end authentication on a civilian signal, protecting receivers from spoofing attacks.
OSNMA is being pioneered by the Galileo Programme, with Septentrio providing a test bed for this technology from the end-user point of view. GNSS include such as the American GPS, European Galileo, Russian GLONASS, Chinese BeiDou, Japan’s QZSS and India’s NavIC. These satellite constellations broadcast positioning information to receivers which use it to calculate their absolute posit ....

Galileo Elliptical Auxiliary Satellites Removed from Service


Two Galileo satellites launched in 2014 by a Soyuz rocket into erroneous orbits, which had been briefly set healthy late last year, have now been removed from service. The change stems from the discovery that, while the vast majority of users obtained an improved positioning, some commercial receivers had difficulty with the satellites’ highly elliptical orbits, created by the malfunction in the Russian launch vehicle.
The European GNSS Agency (GSA) issued a Service Notice to Galileo Users (SNGU) on February 16:
Galileo SNGU In Force
“On 30 November 2020, flags were removed from GSAT0201 and GSAT0202 satellites, making these satellites available for positioning as auxiliary satellites. Following the removal of these flags, the Galileo Programme set up an observation period to collect user feedback and experience with the use of these satellites. ....

Updated Galileo ICD Previews New Features for Faster TTFF in 2023


The European GNSS Agency (GSA) released a new Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD), the second issue of this document geared towards GNSS receiver manufacturers. Although the modified signals are not yet broadcast by Galileo satellites, the ICD will allow GNSS receiver manufacturers to prepare for the improved signals, set for debut in 2023.
Among other updates, three new features are introduced to the I/NAV message transmitted on the Galileo E1-B signal component: Reduced Clock and Ephemeris Data (RedCED); Reed-Solomon Outer Forward Error Correction Data (FEC2); and Secondary Synchronization Pattern (SSP).
The OS SIS ICD v.2.0 is available for download in the Programme Reference Documents section of the European GNSS Service Centre (GSC) web portal. ....
