JAXA and DLR co-operation

JAXA and the German Aerospace Centre (DLR) signed a letter of intent concerning mutual cooperation for satellite disaster monitoring. Both parties confi rmed a mutual intention to use JAXA’s ALOS and DLR’s TerraSAR-X – both of which carry a SAR instrument – to improve response to disasters. They will exchange data as required on requests for emergency observations. They also agreed that will start collaborative research related to disaster monitoring. www.jaxa.jp

USGS adds NASA’s EO-1 satellite imagery

USGS has expanded its free web-enabled archive of earth observation data by including over 83,000 additional satellite images from NASA’s Earth Observing -1 (EO-1) satellite. Both the existing and all future EO-1 imagery will supplement the USGS archive of free, land remote sensing imagery resources. EO-1 sensor data can be previewed and downloaded at no charge via the EO-1 website. www.usgs.gov

Applanix introduces RapidOrtho 2.0

Applanix released RapidOrtho 2.0, a software enhancement for the Digital Sensor System (DSS). It is a complete airborne digital imaging system for fi rst responders and geospatial professionals who need to deliver rapid, highly-accurate ortho-rectifi ed imagery without timeconsuming and expensive ground surveys. A new utility allows to import and convert readily available DEM datasets – including Lidar data – into the RapidOrtho format; this means fi rst responders can utilize any locally-available elevation data for rapid delivery of orthophotos. www.applanix.com

UltraCamXp Wide Angle

Vexcel Imaging GmbH has released UltraCamXp Wide Angle, a new version of the UltraCam large format digital aerial camera system that features a wideangle lens with a shorter focal length. It allows lower-fl ying airplanes to collect data at the same ground sample distance (GSD) as higher-fl ying planes carrying the UltraCamXp, while delivering comparable image quality. www.microsoft.com

New aerial images of Australia online

Fugro released a new on-line aerial image service for professional business users such as surveyors, engineers, architects, planners and developers. High resolution imagery of selected areas of Australia can be viewed and purchased via the website www.fugroworld.com and downloaded as a jpeg or ecw file to the desktop. These images are orthorectified to enable customers to display added features like street names and mapped boundaries etc. www.fugro.com

NASA Lunar Satellite

NASA reported that its Lunar Reconnaissance Orbiter, or LRO, has successfully completed its testing and calibration phase and entered its mapping orbit of the moon. The spacecraft already has made signifi cant progress toward creating the most detailed atlas of the moon’s south pole to date. Scientists released preliminary images and data from LRO’s seven instruments. www.nasa.gov

Vietnam’s RS satellite model completed

Vietnamese engineers have completed the technical model of the country’s fi rst remote sensing satellite. The Pico-Dragon satellite is expected to be launched between 2010 and 2011. The launching of the satellite, whose functions include taking highresolution photographs of natural resources, aiding weather forecasts and monitoring phenomenon like storms, will be a test of Vietnam’s ability to make its own satellites. Made by STI in cooperation with Japan Aerospace Exploration Agency, Pico-Dragon weighs less than two kilograms with 10x10x10 centimetre dimensions and will have a life expectancy of around six months. www.vnbusinessnews.com

ISRO updates

GAGAN

The final operational phase of the Indian SBAS – GAGAN was initiated in June 2009. The system is expected to be ready for testing in about 18 months. The Technology Demonstration Phase for GAGAN was successfully completed in August 2007, as part of which eight Indian Reference Stations (INRES) were installed at eight airports around the country. The INRRES are linked to the Master Control Centre (MCC) near Bangalore from where the Indian Land Uplink Station (INLUS) transmits correction signals to the space segment having GAGAN navigation payload, which translates these signals to the GPS for reception by a GPS SBAS receiver. The fi rst navigation payload is being fabricated and it is proposed to be fl own on GSAT-4 which is expected to be launched later this year. Two more payloads will be subsequently fl own, one each on the geostationary satellites, GSAT-8 and GSAT-12

IRNSS

IRNSS is expected to be implemented in the next fi ve to six years. The management structure for system implementation has been established and work on the detailed system defi nition (space segment and ground segment) has begun. IRNSS satellites will transmit ranging codes and navigation data in S and L-5 bands. The navigation software and user receiver specifi cations are being fi nalized. The IRNSS constellation will have seven satellites – three in Geostationary Orbit (GSO) and four in Near-GSO. The spacecraft confi guration has been fi nalized and all the satellites of the constellation are being confi gured identically. A massive procurement strategy has been formulated and procurement of components and strategic materials for ten spacecraft has been initiated. The spacecraft is basically confi gured with I-1K Bus to be compatible for launch onboard PSLV. However, detailed analysis based on a study found that it is possible to launch two numbers of inclined orbit satellites in one fl ight of GSLV.

GSAT-4

In the past year, main structure of GSAT-4 was delivered and North, South and equipment panels have been realized. Disassembled mode IST and assembled mode IST has been completed and the spacecraft is undergoing thermovac test. GSAT-4 is planned for launch by GSLV later this year and will be positioned at 82 deg E longitude. Excerpts from ISRO Annual Report 08-09
