GlobalTop unveils Mediatek Multi-GNSS module

FireFlyX1 by GlobalTopGlobalTop Technology has launched FireFly X1, the smallest Mediatek-based Multi-GNSS module in the world. With an ultra-compact size of 9.0 x 9.5 x 2.1 mm, it’s one of the smallest Multi-GNSS modules in the industry.

“Compact size and low-power consumption will be the key USP’s for the next generation of M2M Devices. After a comprehensive market study, we found that small size was one of the most important factors for companies when it came to GNSS module selection; other key factors included Read more…

QinetiQ develops GNSS receiver for Galileo PRS

QinetiQ has announced a major breakthrough in developing a robust navigation receiver which will support the new global navigation satellite system (GNSS) Galileo, and particularly the secured Public Regulated Service (PRS) which could become of great use to the shipping and ports sector.

QinetiQ’s new high-performance, next-generation GNSS receiver is multi‑constellation and multi‑frequency, and is designed to process encrypted signals from the Galileo PRS service as well as open services such as GPS. Read more…

UTC adjusted by leap second addition

The Coordinated Universal Time (UTC) time standard, based on atomic clocks, is widely used for international timekeeping and as the reference for time in most countries. UTC is the basis of legal time for most of the world.

UTC must be adjusted at irregular intervals to maintain its correlation to mean solar time due to irregularities in the Earth’s rotation. These adjustments, called leap seconds, are pre-determined. Read more…

First position fix with Galileo satellite-5

Galileo’s fifth satellite (FOC), recently recovered from the wrong orbit, has been combined with three predecessors (IOV) to provide its first position fix.

Galileo fix using fifth satellite

Galileo fix using fifth satellite

Test receivers at ESA’s technical centre in Noordwijk, the Netherlands, and at the Galileo In-Orbit Test station at Redu in Belgium received the signals at 12:48 GMT on 9 December from the quartet of satellites and fixed their horizontal positions to better than 2 m. This achievement is particularly significant because the fifth satellite is the first of a new design of 22 Galileos set to be launched over the next few years. Read more…

Galileo signal tracked by Rockwell Collins S-SDR receiver

Rockwell Collins, a pioneer in the development of commercial and military navigation technology over the past 35 years, has successfully received and tracked a Galileo satellite signal using a prototype Global Navigation Satellite System (GNSS) receiver designed for secure military use.

“This milestone reinforces our belief that Rockwell Collins is uniquely positioned to produce a navigation receiver that will meet global needs,” said John Borghese, vice president of the Advanced Technology Center for Rockwell Collins. Read more…

Public Consultation on Galileo Open Service Signal In Space ICD

The Galileo Open Service Signal In Space Interface Control Document (OS SIS ICD) contains the publicly available information on the Galileo Signal In Space. It is intended for use by the Galileo Open Service (OS) user community and specifies the interface between the Galileo Space Segment and the Galileo User Segment. Read more…

First 50 Galileo fixes certified

Billions of satnav position fixes are performed daily, but determining your place in the world using Galileo system is quite new. So ESA offered to issue certificates for the very first 50 Galileo fixes, provoking responses from across the whole world.

The surprise was the extent of Galileo’s reach. While half the applications came from Galileo’s home continent, others came from the rest of the world, including Australia, Canada, China, Egypt, New Zealand, Russia, USA and Vietnam. Read more…

Galileo maritime trial route

Results are being processed from the first Galileo maritime trials outside of mainland Europe. The long-range, high-latitude testing spanned the North Sea, following the same historical sailing route that Viking dragon-ships used 1200 years ago.

The Belgian frigate Leopold I-F930  during the first high-latitude trials of Europe’s Galileo satellite navigation system sailed first from the Dutch marine base of Den Helder on 4 December 2013 to Stavanger in Norway. From there it progressed north in very rough seas with 10-m high waves, coming close to the Arctic circle on 17 December (a first for Galileo PRS observations) before heading homeward. Read more…
