Second Russian SBAS Satellite Prepared for Launch

August 1, 2012By

Luch-5B, the second of a set of three geostationary satellites being launched to reactivate Roscosmos's Luch Multifunctional Space Relay System, has been delivered to the Baikonur Cosmodrome. It arrived together with the Yamal-300K satellite in a single shipping container aboard an Antanov An-124-100 Ruslan flight from Krasnoyarsk. read more

The International GNSS Real-Time Service
The International GNSS Service has embarked on a project to provide a high-accuracy GPS satellite orbit and clock data service in real time. The service will also provide 1-Hz data streams of GPS and GLONASS data from a network of global continuously operating reference stations. The IGS real-time data and orbit and clock products will be of immense benefit for geoscience studies and a host of other science and engineering applications. A team of authors associated with this project discusses the genesis and status of the real-time service and the plans to provide an initial operating capability. read more

Preparing for the Next Generation: The Multi-GNSS Asia Demonstration Campaign

December 1, 2011By

A dramatic increase over the next five years to roughly 100 GNSS satellites in the skies over Asia and Oceania makes that region the fastest growing area in GNSS. The Multi-GNSS Asia (MGA) initiative, a cooperative international demonstration campaign, seeks to take full advantage of this scientific and technical windfall, gaining early experience with the new signals and services of multi-constellation GNSS. read more

Integrity for Non-Aviation Users: Moving Away from Specific Risk

July 1, 2011By
Pullen-Open2

Non-aviation users of satellite- and ground-based augmentation systems do not require the conservative level of integrity built into these systems for aviation users. Removing it can produce substantial benefits in terms of smaller error bounds and improved availability. read more

On-Site Geo-Referencing of 3D Static Terrestrial Laser Scans

June 29, 2011By

By Jens-André Paffenholz This blog presents an efficient procedure for directly geo-referencing static 3D laser scans. This is a worthwhile way to obtain the required transformation parameters from the local sensor-defined coordinate system to a global system. Therefore, a multi-sensor systems (MSS) is designed with a phase-measuring laser scanner and 3D positional sensors (see Figure 1). By means of at least... read more
