Nacho Romero has recently pointed out that CHAT is not tracking unhealthy
satellites, and he has also informed me that many analysis centers are
apparently not processing CHTI.

We announced several years ago that CHAT was to be replaced by CHTI situated
about 20 km away, and that CHAT would probably go off the air once any of its
aging equipment failed.

CHTI and CHAT have now been running in parallel since 2007/345, and we can make
no guarantee about the continued operation of CHAT.

We encourage all analysis centers to process CHTI (as well as CHAT) in routine
processing and in any reprocessing.

Thank you,
John
