2015-01-13 17:56:52| rfglobalnet Downloads
In the past few years, the exponential growth of wireless devices has created significant challenges for spectrum regulators. As a key piece of the wireless economy infrastructure, spectrum needs to be well managed and able to transmit data without interference, whether malicious or accidental. This article provides an overview of contemporary radio spectrum monitoring practices, and introduces a sensor and geolocation technologies that can meet emerging challenges.

Computer Systems Engineer for Herschel Science Operations
2015-01-13 16:07:00| Space-careers.com Jobs RSS
Aurora is an established supplier of skilled manpower to ESA and in particular at ESTEC and ESAC. Aurora has the opportunity to expand our support within the Science and Robotic Exploration Directorate DSRE. Aurora currently has a team of 20 engineers and scientists at ESAC including support to Herschel. We require a service to be provided by a parttime circa 50 software engineer with experience in system administration and support, preferably in a science operations environment. ESA will award the work to the company with the best proposal and Auroras existing experience on providing support to the Computer Support Group CSG and the Herschel mission is beneficial to our commitment to produce an excellent proposal to ESA. Overview The work is to provide a number of specialised services to support ESA in Computer Systems Engineering at ESAC for the operations of the Herschel Science Centre HSC. The Herschel Space Observatory was launched in May 2009. It performed astronomical photometry and spectroscopy in the far infrared and submillimetre 57670 micron wavelength range. Its scientific payload consisted of three instruments using a variety of detector technologies developed by Principal Investigator teams at various institutions, predominantly in Europe but with a significant contribution from the US. The majority of its observing time was provided to the general user community, via annual Calls for Proposals. Since May 2013, the Herschel spacecraft has had no liquid helium coolant remaining to allow the science instruments on board to operate, hence regular operations have ceased and the spacecraft has been placed into a nonreturning Solar orbit. In the ongoing postoperations phase, the Herschel Science Centre HSC, located at ESAC, is, inter alia, responsible for supporting data analysis improvements, oversight of the calibration and crosscalibration of the science instruments, and the generation of standard science products and their quality assessment as final Herschel archive products. All observational data has been systematically processed to generate these products that are distributed to the astronomical community via the Herschel Science Archive HSA, developed and maintained at ESAC. With the complete set of data from mission operations now in hand it is possible to further improve the calibration and data products in the archive. The SREO Computer Support Group CSG is providing computer support to all science operations centres and science ground segments located at ESAC, either in development or in operational phase. Under this work package, service shall be provided to support ESA in system administration activities for those computer systems used for science operations and research activities.

Is meaningful action to address climate change possible given our economic systems?
2015-01-13 16:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Triple Pundit: Its increasingly obvious that the global economic system, and particularly the current brand of U.S. capitalism, are not really compatible with the actions needed to combat climate change. Naomi Klein makes this point clear in This Changes Everything, which is both a passionate and controversial polemic and a reasoned discussion of the issues and forces stalling, and indeed preventing, a comprehensive response to climate change. The problem is not the political and ideological divisions or scientific...
