MTSAT-1

 1999-F04

---

The Multifunctional Transportation Satellite is built by SS/Loral for Japan Ministry of Transport MTSAT is an FS-1300 for Japanese Transport Ministry, Civil Aviation Bureau and Meteorological Agency. It will be launched in Aug 1999 by H-2. The H-2 was modified to use the new LE-5B engine in its second stage. Uses 5S fairing.

Mass 2900 kg launch. Size 4.5m x 3.3m, span 33.1m. Shape box + panel + boom + 2 antennae. Station 140E. Dry mass 1445 kg or 1250 kg.

The aeronautical mission provides voice and data communications and positioning data, allowing aircraft positions to be transmitted to air traffic control. It also provides GPS augmentation.

The meteo mission has an image sensor with visible and IR channels, following on from the GMS series. Meteo data is relayed to JMA, and MTSAT relays other meteorological data.

The satellite was lost when the launch vehicle failed during first stage burn. The first stage debris fell in the Pacific 380 km NW of Bonin Is. and 1250 km SE of TNSC. A failed turbopump blade in the LE-7 main engine was blamed.
