it’s a measure of the transmission time for you and through the airplane, and so of this plane’s distance through the satellite. It doesn’t identify a solitary location but instead all equidistant locations—a approximately circular group of possibilities. Because of the range limitations of MH370, the near-circles could be paid off to arcs. The essential essential arc is the 7th and final one—defined by one last handshake tied up in complex how to fuel fatigue therefore the failure of this primary machines. The 7th arc stretches from Central Asia within the north to your vicinity of Antarctica when you look at the south. It had been crossed by MH370 at 8:19 a.m., Kuala Lumpur time. Calculations of likely journey paths place the airplane’s intersection using the 7th arc—and therefore its end point—in Kazakhstan in the event that airplane switched north, or within the Indian that is southern if switched south.

Technical analysis shows with near certainty that the airplane switched south

We realize this from Inmarsat’s second logged value—the burst-frequency offset. In the interests of simpleness, i am going to reference this value once the “Doppler value,” since it includes, many crucially, a way of measuring radio-frequency Doppler shifts connected with high-speed movement in terms of satellite position, and it is a part that is natural of communications for airplanes in journey.
