These systems would require such advanced sensor technologies as focal plane arrays and laser radar.

It disposes of an ultra precise Satellite Laser Ranging System (SLR), a permanently recording Global Positioning System (GPS) receiver, a radar altimeter transponder, software expertise for GPS, laser and altimetry data reduction and processing.

The laser radar system for detecting space debris has been investigated by an ISAS group led by T. Yokota.

Five periods of measurement with lidar instruments were carried out in 1994.

For example, the lidar system compiled a complete map of lunar elevations, discovering a 12 kilometer deep impact crater at the lunar south pole in the process.

At the Andøya Rocket Range, scientific rockets are launched and the international Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) facility uses light detection and ranging (lidars) to study the middle and upper atmosphere.

The second of NASA apos s new techniques for environmental observation was lidar using a laser in a manner similar to radar by bouncing it off objects (e.g. clouds, pollutants, the Earth apos s surface) and then making environmental measurements from the reflected energy.

The TIRA system consists of a narrow band tracking radar and a high resolution imaging radar.

The beam splitters and lenses are represented by physical objects, and the system projects down the laser beam path.

The TIRA system consists of narrow band tracking radar and high resolution imaging radar.

The system is composed of a Nd Yag laser, a light beam expander, a telescope, a CCD camera, a photo multiplier and a computer.

Under an agreement with NASA, ASI has developed the High Gain Antenna, the radio frequency system for the Radio Science Subsystem (RFIS), the CASSINI Radar RF experiment (RFES) and the Visual Infrared Mapping Spectrometer (VIMS).

1.2.2 Radar and optical measurements from space

The observatory, which will have five laser systems, of which three are already operational, as well as a number of ground measurement systems, is unique.

. Major efforts in the development of space based laser systems were devoted to remote sensing instrumentation.

To a certain extent, TIRA is additionally used to gain radar data of space debris and meteoroids.K. Magura and D. Mehrholz, Measurement and analysis techniques for satellite observations used at FGAN FHP , FGAN FHP, Technical Report, 8 93 (Wachtberg Werthhoven, December 1993).

(a) Boosting the production of equipment for the fuel and energy sector, including laser measuring systems, optoelectronic flame control systems, instruments to measure gas density, multiphase pumping plants and control systems for high performance gas pumping stations

Radar data of selected space debris are gained in the tracking mode of operation using the Tracking and Imaging Radar system.

Denmark has deployed a temporary solution by providing a radar to enhance situational awareness for controllers at Kabul International Airport, although this radar will need to be replaced by a permanent civilian air traffic control certified radar.

CNES will provide the altimeter and the Doris system, while NASA will supply the radiometer, the laser reflector and the positioning system.

(e) GaAlAs laser system with direct wavelength division multiplexing and direct detection receiver

Using a unique technique for concentrating the solar light, splitting the spectrum to various spectral bands, and using each band for direct optical pumping of different lasers near their emission band resulted in an overall efficiency of 20 per cent.

In ALOHA 93, a sodium lidar, optical imager, and spectrometer gathered data from an aircraft, the flights being coordinated with selective overpasses of NASA apos s UARS (launched in 1991).

Additional Universal Interface Terminal systems and stand alone SAR geocoding systems were also installed.

. Spaceborne laser systems could also play an important role in the area of inter satellite and inter orbit communications.

The development of the laser based uranium 233 clean up system, a crucial element in the thorium utilization programme, has made significant progress.

Recalling the continuous development of satellite systems for obtaining global data by optical and radar sensors to a level of importance to national mapping requirements, starting from Landsat in 1972 to QuickBird in 2000 and from Seasat 1978 to the Shuttle Radar Topographic Mission in 2000,

(f) Organization of permanent stations with GPS and laser equipment for geodynamic investigation.

We studied the acoustics with laser stuff, and they bounce them off this and see where it all works.

The Nepomuk system is not activated. Unable to answer queries without it.

In fact, the application of light detection and ranging (lidar) instruments was considered an extremely promising new way of obtaining essential atmospheric and geophysical parameters on a global scale.

These include the Internet, the optical disk system (ODS) and the United Nations Bibliographic Information System (UNBIS), together with its by product UNBIS Plus on CD ROM.

FS research and development of airborne video, digital cameras, radar, and GPS systems continued to address numerous ecosystem management applications.
