QuickBird Satellite Mission Ends

European Space Imaging has announced that on Tuesday 27 January, after 13 years of excellent performance, QuickBird approached its end of mission smoothly and re-entered the Earths' atmosphere at 01:59 UTC above the South Atlantic Ocean near southern Brazil. DigitalGlobe confirms that QuickBird de-orbited successfully. QuickBird was in orbit for more than 13 years, far exceeding its designed mission life. The satellite made over 70,000 trips around the Earth, contributing substantially to DigitalGlobe’s unmatched imagery catalogue and thus the understanding of our changing planet. The company thanks its customers and partners for their support of a very successful mission. Imagery... (read more)

Modernized GPS Satellite Launched

The fourth US Air Force modernized Global Positioning System Block IIR (GPS IIR-M) satellite was launched successfully from Cape Canaveral Air Force Station aboard a United Launch Alliance (ULA) Delta II launch vehicle. Designated GPS IIR-17M, the satellite is the fourth in a series of eight Block IIR-M spacecraft that Lockheed Martin Navigation Systems has modernised for its customer, the Global Positioning Systems Wing, Space and Missile Systems Center, Los Angeles Air Force Base,CA, USA. The Block IIR-M series includes new features that enhance operations and navigation signal performance for military and civilian GPS users around the globe. Each... (read more)

GOCE Earth Explorer Satellite

The European Space Agency is about to launch a mission to investigate the Earth's gravitational field and to map the reference shape of our planet - the geoid - with exceptional resolution and accuracy. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) will be placed onto a low altitude near sun-synchronous orbit by a Russian Rockot vehicle launched from the Plesetsk Cosmodrome in Nothern Russia, some 800 km north of Moscow. Lift-off is scheduled to take place at 16:21 CEST (14:21 UTC) on 10th September. The launcher is operated by Eurockot Launch Services, a joint venture between EADS Astrium... (read more)

China Imaging Satellite

In November last year China successfully put into orbit the third of its ZY-2 second transmitting-type remote sensing satellites. China launched the first and second ZY-2 satellites in September 2000 and October 2002, respectively, and these are still in orbit. Compared with these previous two satellites, the third has improved overall performance and technology. The satellite is mainly meant for land resource surveying, environmental supervision and protection, city planning, crop-yield assessment, disaster monitoring and space scientific experiment. The launch marked the 82nd time that Long March carriers have been used and the fortieth consecutive successful launch since China launched the... (read more)

Fire Monitoring by Satellite

Testing of the operational ScanEx Fire Monitoring Service (SFMS) has been started. The service has been developed at the ScanEx Research and Development Center and unlike similar systems (e.g., NASA Rapid Fire, AFIS, etc.) it offers access to data of several satellites of low, middle and high resolution. For the purpose of the project daily satellite imagery of the Russian territory is carried out with the data received at UniScan ground complexes, deployed in Moscow, Irkutsk and Magadan. At the first stage of the service testing in July only data of the European part of Russia will be used (within... (read more)

Multi-temporal Satellite Imagery

Taiwan lies at the border of the Eurasian and Philippine Sea Plates and faces the Pacific Ocean. Earthquakes and typhoons are the two main threats, and can cause landslides, debris flow, flooding and other natural hazards. In 2005 the World Bank categorised Taiwan as the most vulnerable country in the world in terms of the percentage of exposed areas and multiplicity of disasters. Given these circumstances, planning for hazard mitigation is important, as is management for hazardous conditions. Also necessary are decision-support tools for understanding firstly where disaster is likely to occur, secondly, when, and thirdly what kinds of disasters... (read more)

High Resolution Satellite DTMs

GeoEye-1 stereo satellite imagery is capable of producing Digital Terrain Models (DTM) with better then 0.5m vertical accuracy. AAMHatch tasked the GeoEye-1 satellite to capture stereo data over a 270sqkm area in Eastern Australia. The application was an engineering study for the energy sector with the client requiring a 0.5m ortho-image with 2m contours. GeoEye-1's unsurpassed agility and maneuverability assists in rapid stereo capture. This image was cloud-free, and delivered to AAMHatch for processing within 48 hours of capture. Survey accurate ground control points, distributed evenly across the area, were used in the image processing. These points enabled... (read more)

New GPS Satellite Operational

The fourth in a series of eight modernized Global Positioning System (GPS) satellites that will deliver new capabilities to military and civilian users has been declared fully operational. Launched from Cape Canaveral October 17, the satellite was given the all clear after an on-orbit checkout by a combined U.S. Air Force/Lockheed Martin team. Read more The satellite joins three IIR-M satellites and 12 other operational Block IIR satellites within the current 28-spacecraft constellation. The fifth GPS IIR-M satellite is scheduled for launch on 20th December 20, 2007 from Cape Canaveral. (read more)

Satellite Imagery for Mapping

The ICA Commission on Mapping from Satellite Imagery is responsible for educating and informing the geospatial- data handling community about the link between the raw data captured from satellite imagery and the extraction, presentation and application of information derived from such data. See previous report on this page, GIM March 2007. ToR The Terms of Reference of the 2007-2011 commission, approved at the Moscow ICC, August 2007, include fundamental work: “[…] analysis of existing and forthcoming satellite imagery in view of their potential inputs for producing and updating topographic and thematic maps and databases; and assessment of the cartographic capabilities...

Mapping from Satellite Imagery

The emergence of new, low-cost, internet-based mapping tools like Google Earth, Google Maps, and NASA World Wind that make thousands of satellite images available to a wide audience has greatly influenced perception and awareness. This goes for both the general public and the scientific community, who now see the enormous potential of mapping from satellite imagery. Such tools highlight the crucial role of remote sensing in providing fast, up-to-date cartographic information for informed decision making, particularly for rapid mapping of pre- and post-disaster events, emergency planning, geomarketing, or even simpler activities like planning a holiday trip. The ICA Commission on... (read more)
