UPDATE: EGNOS Satellite Launch Set for August 6

June 21, 2012By

  News courtesy of CANSPACE Listserv. UPDATE: The Interfax news agency has announced that the rescheduled launch date for SES-5 from the Baikonur Cosmodrome, originally scheduled for June 18, is August 6, 2012. The launch is being delayed due to a problem with a first stage subsystem on the Proton launch vehicle. The rocket has been rolled back to the... 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
