China has launched commercial and public services across the Asia-Pacific region on its domestic satellite navigation network built to rival the US global positioning system. http://phys.org/news275890565.html Space & Earth Fri, 28 Dec 2012 04:16:12 EST news275890565 (Phys.org)—Four of the instruments on the Metop-B weather satellite (AMSU-A, ASCAT, MHS, GRAS) have been activated this week and are delivering data.   This demonstrates that Metop-B, launched on 17 September, is performing well and is on its way towards replacing the ageing Metop-A as prime operational satellite in polar orbit, after the six-month commissioning phase. The Advanced Scatterometer (ASCAT) and Microwave Humidity Sounder (MHS) are innovative European instruments. ASCAT delivers information on near-surface wind speed and direction over the global oceans and soil moisture over land, while the MHS delivers information on atmospheric humidity in all weather conditions. http://phys.org/news268301239.html Space & Earth Mon, 01 Oct 2012 09:07:28 EST news268301239 NASA has selected a team including Southwest Research Institute to develop the Cyclone Global Navigation Satellite System (CYGNSS), which will provide better prediction capabilities for extreme weather events, particularly the intensification of hurricanes. http://phys.org/news259504717.html Space & Earth Thu, 21 Jun 2012 13:38:58 EST news259504717 NASA has selected an ocean wind study proposal led by the University of Michigan from among 19 submitted to the agency's Announcement of Opportunity for small spaceflight investigations of the Earth system. The proposed mission will make accurate measurements of ocean surface winds throughout the life cycle of tropical storms and hurricanes, which could help lead to better weather forecasting. http://phys.org/news259307598.html Space & Earth Tue, 19 Jun 2012 06:55:09 EST news259307598 (PhysOrg.com) -- Satellite navigation is having an enormous impact on our daily lives. In practical terms it means the only place left to get lost is indoors, where satnav signals fail to reach. But one ESA project is changing that. http://phys.org/news186225425.html Technology Wed, 24 Feb 2010 09:17:51 EST news186225425 (PhysOrg.com) -- A new system is using satellite navigation data to help car drivers develop smart, smooth and safe driving techniques that can help save an average of 15-25% in fuel, as well as contribute to environmental protection. http://phys.org/news154017042.html Space & Earth Mon, 16 Feb 2009 14:31:09 EST news154017042
