Which company manufactures the air data system on the Boeing 787-9 'Dreamliner' I'm asking specifically about the manufacturer and model of the Pitot probes/tubes that provide the pilots with current air speed readings.

Pretty sure it's either UTC or Honeywell but can't find anything definitive online.

P.S - Is there any evidence of this technology being improved? Especially since Air France flight 447, and more recently Lion Air 610, where in both cases the pilots lost control of the aircraft due to inaccurate airspeed measurements.
Boeing procured the avionics for the B787 in "packages". Air data was part of the "Navigation Package" which included in addition to air data, IRUs, nav radios, GPS sensors, and the FMS software.  

Honeywell was selected as the supplier for the Nav package. So they provided the air data system.  I don't know what specific system they supplied.
