Japanese communications technology satellite. Japan's NASDA space agency sponsored the LDREX experimental antenna. Engineering Test satellite built by NEC Toshiba Space Systems for NASDA, Japan. Launched 2000 - 2006.

Status: Operational 2000. First Launch: 2000-12-20. Last Launch: 2006-10-13. Number: 2 . Gross mass: 140 kg (300 lb).

Ariane V138's EPS upper stage carried an ASAP5 small payload attachment ring with a special camera system. LDREX was a 6-m diameter antenna which was to have deployed 40 minutes after launch, to test the deployment mechanism for the larger antenna to be used on the ETS-8 satellite. After the test the antenna was to have been jettisoned. However the experiment failed and no deployment or jettison took place.
