Descending sound from the horn. anything that make waves from the ocean to sound waves and light waves. they were able to more closely pinpoint the location of that plane using the doppler effect. that's how they decided the plane went down in the indian ocean. martha: the technology is remarkable. reaction from the chinese government? reporter: they are demanding to see this new satellite data. keep in mind the evenings in this part of the world between these countries is emreally high. it was extremely high even before this incident. ing threats from islamic terrorists. and china has deporte...

Assumptions regarding auto pilot speed. the analysis arrived at a path of flight which was peer reviewed by britain's air safety agency. the air accidents investigation branch. before being submitted to malaysian authorities yesterday. >> this is the first time we've ever been asked to try to find something with just a single signal once an hour. really a great tribute to our scientific team they managed to achieve this. in very simple terms, we have used the difference in speech in which the signal has come from the aircraft to the fixed point, the satellite in space. it's called doppler effe...

Piece. this is about in-depth analysis, understanding the data and being able to extract information that it was not designed to do. remember, these inmarsat satellit satellites, 22,000 miles up are there to pass data about the status of the aircraft, status of the aircraft's engines. so you're repurposing that and trying to work the math and work back through the information to determine location data and extract it out of this data that it truly wasn't meant to provide. >> and it's interesting because when they were analyzing the radar data, a number of the analysts said it's a bit of an art...

This equation. another part is called the doppler effect. you hear weather people talk about it all the time. in terms of the location on the earth, just for understanding it, imagine the satellite is about 22,000 miles above the earth if you went straight down. if it sent a signal out, a handshake with a plane out back, that would mean that the plane is in a certain area. then, if you did it again and it were further, took longer to get that signal, it would suggest that it was further out somewhere. that's how they established the pattern of the dots right here a. series of signals that they...

Or outside the circle. that's the doppler effect. i'll take you to what i believe the doppler effect is especially for the first ping. we say 2:11. within a couple hundred miles. the plane was flying inside the ring which means it was getting closer to the satellite itself. so this is doppler radar. we use doppler radar to know this is tuscaloosa's tornado. is th this is moving this way by doppler shift. we knew at the time there was a tornado on the ground right there at tuscaloosa. where else can you hear doppler shift? if you hear a fire truck or train or racecar go -- there's a shift. if y...
