EB and MEDAV Announce Interoperability in Radio Channel Measurement, Modeling and Emulation

June 18, 2010 By vani Leave a Comment

OULU, FINLAND and UTTENREUTH, GERMANY, Jun 17 (MARKET
WIRE) —
EB (Elektrobit), a leading developer of cutting edge embedded technology
solutions for wireless and automotive industries and MEDAV, a leading
provider of radio channel sounders announced their cooperation in
developing interoperability between the MEDAV RUSK MIMO Channel Sounder
and EB Propsim emulators. EB Propsim radio channel emulator customers now
have the ability to use in their wireless testing data measured in the
field with the MEDAV RUSK MIMO Channel Sounder.

“Conformance testing against basic industry standards is no longer enough
in today’s competitive markets. A laboratory environment where real world
radio conditions can be repeated accurately is becoming a must for mobile
device developers and operators. The unique and patented file-based
emulation architecture and playback capability of EB Propsim radio
channel emulators together with data measured by the MEDAV Sounder
provide competitive advantage to our customers”, said Antti Sivula,
senior vice president of EB’s Wireless Communications Tools Business. “We
established this cooperation with MEDAV to provide our customers in a
variety of wireless industry markets better access to state-of-the-art
solutions to ensure they are testing beyond conformance for the most
reliable wireless connection possible.”

Actual field measurements performed with the MEDAV MIMO Channel Sounder
provide the most accurate, real-life-like channel models for repeated
tests in the laboratory. In this process the sounder acts like a recorder
and the radio channel emulator as a projector, which plays back the
recorded radio channel data. This can only be performed with an emulator
that uses file-based emulation, allowing the same test run to be
completed as many times as needed – and exactly in the same way.

“Measured data from different environments is already available in our
library and we also perform radio channel measurement campaigns to
customers as a service”, said Horst Jonuscheit, director sales & business
development in MEDAV. “By bringing together MEDAV’s RUSK MIMO Channel
Sounder data and EB Propsim emulator through a data interface, a big
technical gap could be closed for customers worldwide. Users of these
systems can now take advantage of the results attainable from the
combined expertise of EB and MEDAV.”

‘Spiderbots’ inside Mount St Helens may detect impending volcanic eruption

August 15, 2009 By admin Leave a Comment

Washington, August 15 (ANI): NASA scientists have placed about a dozen monitoring ‘spiderbots’ inside the volcanic crater in Mount St Helens in the US, which are high-tech devices that can detect an impending eruption.

Mount St. Helens is one of the most active volcanoes in the US. Its most devastating eruption in 1980, and the most recent seen here in 2004.

According to a report in National Geographic News, about a dozen so-called Spiders were placed on Mount St. Helens in July.

The pods, designed to go where no human can, were lowered by helicopter inside and around the volcano center.

“We can detect the differences between snow falling off of a branch, an animal running by, wind, a thunderstorm and the very subtle signatures of magma moving at depth, perhaps even kilometers beneath the surface of the earth,” said Steve Chien, Principal Scientist, Autonomous Systems, NASA Jet Propulsion Laboratory .

The pods form a virtual wireless network and communicate with each other and a NASA satellite called Earth Observing-1, or EO-1.

Each pod contains a seismometer, a GPS receiver, an infrared sounder to sense explosions, and a lightning detector.

According to Chien, “They have the ability to recognize different kinds of events such as seismic events, earthquakes, that are basically indications that something is happening at the volcano.”

“In the context of volcano monitoring, we want to have the best educated guess to make decisions that will save life and properties,” said Sharon Kedar, Geophysicist, NASA /Jet Propulsion Laboratoy.

NASA would like to someday use this same technology on the surface of Mars to study atmospheric events like dust storms, which are mini-tornadoes, as well as seismic activity. (ANI)

New instrument may detect groundwater deep inside Mars

June 27, 2009 By admin Leave a Comment

Washington, June 25 (ANI): A team of Boulder (US) scientists and engineers has tested a new instrument prototype that might be used to detect groundwater deep inside Mars.

Known as the Mars Time Domain Electromagnetic Sounder (MTDEM), the instrument uses induction to generate electrical currents in the ground, whose secondary magnetic fields are in turn detected at the planetary surface.

In this way, the electrical conductivity of the subsurface can be reconstructed.

“Groundwater that has been out of atmospheric circulation for eons will be very salty,” said the project’s principal investigator Dr. Robert Grimm, a director in the Space Science and Engineering Division at Southwest Research Institute. “It is a near-ideal exploration target for inductive systems,” he added.

The inductive principle of the MTDEM is distinct from the wavelike, surface-penetrating radars MARSIS and SHARAD presently orbiting Mars.

“The radars have been very useful in imaging through ice and through very dry, low-density rock, but they have not lived up to expectations to look through solid rock and find water,” said Grimm.

The time-domain inductive method uses a large, flat-lying loop of wire on the ground to generate and receive electromagnetic signals.

In order to do this robotically, the team developed a launch system that shoots two projectiles, each paying out spooled wire as they fly.

Data taken during the test launches allowed Warden and Grimm to scale the system for a flight mission. The MTDEM prototype deployed to a distance of more than 70 meters.

For Mars, a system deploying a 200-meter loop would be less than 6 kilograms mass and could detect groundwater at depths up to 5 kilometers (3 miles). Most of the instrument’s mass would be in the loop and deployment system.

According to Barry Berdanier, the Ball electrical engineer who built the MTDEM electronics, the flight electronics would comprise just a few hundred grams.

“Electromagnetic induction methods are widely used in groundwater exploration,” said James Pfieffer of Zapata Incorporated, a geophysical firm that provided field support.

“Subsurface, liquid water on Mars could be a habitable zone for microbes. We know that huge volumes of discharged groundwater have shaped Mars’ ancient surface,” said Grimm. (ANI)

New NASA model to improve forecasting of deadly cyclones

April 14, 2009 By admin Leave a Comment

Washington, April 14 (ANI): NASA has used satellite data and a new modeling approach that could improve weather forecasting and save more lives when future cyclones develop.

About 15 percent of the world’s tropical cyclones occur in the northern Indian Ocean, but because of high population densities along low-lying coastlines, the storms have caused nearly 80 percent of cyclone-related deaths around the world.

Incomplete atmospheric data for the Bay of Bengal and Arabian Sea make it difficult for regional forecasters to provide enough warning for mass evacuations.

In the wake of last year’s Cyclone Nargis, which was one of the most catastrophic cyclones on record, a team of NASA researchers re-examined the storm as a test case for a new data integration and mathematical modeling approach.

They compiled satellite data from the days leading up to the May 2 landfall of the storm and successfully “hindcasted” Nargis’ path and landfall in Burma.

“Hindcasting” means that the modelers plotted the precise course of the storm.

In addition, the retrospective results showed how forecasters might now be able to produce multi-day advance warnings in the Indian Ocean and improve advance forecasts in other parts of the world.

“There is no event in nature that causes a greater loss of life than Northern Indian Ocean cyclones, so we have a strong motivation to improve advance warnings,” said the study’s lead author, Oreste Reale, an atmospheric modeler with the Goddard Earth Sciences and Technology Center.

In their modeling experiment, Reale’s team detected and tracked Nargis’ path by employing novel 3-dimensional satellite imagery and atmospheric profiles from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA’s Aqua satellite to see into the heart of the storm.

AIRS has become increasingly important to weather forecasting because of its ability to show changes in atmospheric temperature and moisture at varying altitudes.

Lau, chief of Goddard’s Laboratory for Atmospheres, believes that regional forecasting agencies monitoring the region can readily access AIRS’ data daily and optimize forecasts for cyclones in the Indian Ocean.

According to Lau, the same technique can be useful to forecasts of hurricanes in the Atlantic and typhoons in the western Pacific, particularly when the storm is formed over open oceans out of flight range of hurricane-hunting airplanes.

“With this approach, we can now better define cyclones at the early stages and track them in the models to know what populations may be most at risk,” explained Reale. “And every 12 hours we gain in these forecasts means a gain in our chances to reduce loss of life,” he added. (ANI)
