John Zweck, an Australian Ph.D. in math now teaching at UT/Dallas, has posted satellite trajectory data in 1 second steps at:
Aqqa on MH370
About 2/3 down the page:
"The satellite position data from STK in 1 second time steps between March 7th 1100Z and March 8th 1100Z are available in the ECEF (fixed) frame and the WGS 84 frame. The LLA version includes latitude, longitude and altitude (geodetic height) above the WGS 84 ellipsoid and the LLR version includes latitude, longitude and radius from the centre of the WGS 84 ellipsoid."
Followed by links to files in several different formats.
