I have heard of Inmarsat before, as a provider of satellite-based IP and telephony services.
Perhaps a device utilizing their service was in use on the plane (for in-flight broadband, perhaps?), and Inmarsat was able to review their usage data to help determine the plane's course.

The aircraft's SATCOM system continued to respond to those pings for a number of hours after it disappeared, and the new location information is based on analysis of the series of pings that occurred.
