CHC Navigation’s GNSS Receivers Reach the Peak of Everest

CHC Navigation’s P5 geodetic GNSS receiver has been used successfully by China's National Geodetic Survey Team and Mountaineer's Team to complete the 2020 Mount Everest Elevation Survey. This extreme GNSS surveying project leveraged the performance, reliability and operability of CHC Navigation’s receivers in very challenging temperature and altitude conditions. This was the first time that a team of Chinese surveyors had climbed the summit of Mount Everest, and was also the first time that BeiDou-based Chinese GNSS receivers had been used to measure the height of Mount Everest. In order to promote research on the Mount Everest elevation and to... (read more)

The Evolution of FLEPOS 3.0

Next-generation Real-time Network for Flanders
A continuously operating reference station (CORS) provides GNSS data to support very accurate 3D positioning and additional geophysical applications. Flemish Positioning Services (FLEPOS) is the real-time global navigation satellite system (GNSS) CORS network for the Flanders region in northern Belgium. This article outlines the evolution of the next generation of the real-time network, FLEPOS 3.0. FLEPOS is part of Informatie Vlaanderen, a Flanders public administration organization. The first version of FLEPOS was established in 2002. Between 2002 and 2018, FLEPOS evolved through version 2.0 into the current FLEPOS 3.0 RTK real-time network (RTN) thanks to support from the Trimble Network... (read more)

New GNSS Receiver Module Opens Door for Ultra-precise Positioning for High-volume Applications

Septentrio has announced that it is starting high-volume production of mosaic TM-X5, the next-generation multi-constellation and multi-band receiver module. Featuring the latest GNSS technology, mosaic TM-X5 brings centimetre-level positioning to technologies such as robotics, automation, smart wearables and telematics, among others. Its small form factor and low-power design makes high-performance positioning accessible to volume applications. “For smooth, uninterrupted operation in the field, mosaic TM-X5 is the logical choice for an industrial-grade GNSS positioning module,” said Francois Freulon, head of product management at Septentrio. “In an industrial setting, the cost of equipment downtime can quickly get out of hand. We designed mosaic TM to be robust in difficult environments, ensuring continuous operation as well as quick set-up times for our customers.” Compatible with all GNSS constellations Septentrio’s mosaic TM-X5 was conceived to be one of the first GNSS receiver modules...

Using PPP Corrections in Precise Real-time Applications

Minding the Gaps
Satellite-delivered GNSS correction services can be used in many real-time applications where real-time kinematic (RTK) and virtual reference stations (VRS) are not available. In areas without regular communication systems, satellite-broadcast PPP corrections can deliver centimetre-level positioning worldwide in real time. While geospatial professionals who use RTK and VRS enjoy reliable, cost-effective performance in a broad array of tasks, there are many instances where conditions conspire to make working in real time difficult or even impossible. For example, hilly terrain may block radio signals from an RTK base station, while inconsistent cellular coverage can disrupt or cut off communications with the... (read more)

GNSS Receivers – Evolution or Revolution?

Past, Present and Future of Positioning
Satellite surveying… are there any industry professionals out there not using it on (almost) a daily basis? Over the last 30 years, GNSS has become the main positioning instrument for most applications, writes Huibert-Jan Lekkerkerk. Of course, there are still some exceptions where correct relative positioning is needed and dedicated optical systems such as a total station or level instrument are used, but even these are often set up over control points determined using GNSS techniques. This article investigates the developments in GNSS over the last decade and attempts to predict the future. Around a decade ago, a review of... (read more)

ESA Leads Drive into 5G Positioning Future

A pair of testbed vehicles went out on the road in Germany to simulate the way we are all likely to be using 5G positioning services in the future. The field test focused on assessing the performance of highly precise ‘hybrid’ satellite/terrestrial positioning for autonomous vehicles, drones, smart cities and the Internet of Things. The two vehicles were driven for a week around Munich and the surrounding area in a variety of environments, from the open-sky terrain surrounding the German Aerospace Center DLR’s site in Oberpfaffenhofen to the deep urban canyons of the city’s dense Maxverstadt district. As they drove... (read more)

China Announces Worldwide Coverage by BeiDou

At the end of 2018, China’s Satellite Navigation Office announced that the country’s GNSS (called BeiDou or ‘BDS’) is now available as a global service. Originally, worldwide coverage was not expected to be achieved until 2020, but this early completion of the system means that China now joins the USA’s GPS, Europe’s Galileo and Russia’s GLONASS as the only four global providers of satellite-based positioning, navigation and timing (PNT) services. Ran Chengqi, director general of the China Satellite Navigation Office, is quoted as saying that BeiDou has “officially entered the global era as [it] expands from a regional system to... (read more)
