RazakSat

 2009-037A


Abdul Razak bin Haji Dato' Hussein Al-Haj (1922-1976), politician

Malaysia's MACSat (Medium size Aperture Camera sat), named RazakSat after Tun Abdul Razak Dato' Hussain, former Malaysian PM is based on a Korean satellite bus, the SI-200 (KitSat-3 and STSAT-1). Mass is 200 kg.

The ATSB/Kuala Lumpur project is cooperatibe with SatReci/Daejeon, S Korea. Size 1.20m dia 1.20m high hexagon+ 3 panels, 3.0? span.

Launch by Falcon 1.

MOSTI Ministry of Sci Tech and Industry.

The Angkasa (AAN, Agensi Angkasa Negara, National Space Agency) is also involved, and possibly the MACRES (Pusat Remote Sensing Negara, Malaysian Center for Remote Sensing).

Sentinel 5 Precursor

 2017-064A


S5P is a gapfiller between Envisat and Sentinel 5. It flew in a 800 km polar, 1330LTDN SSO orbit, studying atmospheric chemistry at high temporal and spatial resolution. Sentinel 5's main payload will fly on Metop Second Gen.

Kodama

 2002-042B


DRTS, a Data Relay Test Satellite for data relay and intersatellite communications, was built by Mitsubishi. DRTS was named Kodama ('echo'). Originally two satellites were to be launched, but DRTS-E was cancelled in 2001 and only DRTS-W was retained.

DRTS was a box + 2 panels + antenna, mass 2800 kg launch, 1500 kg BOL. 1300 kg dry. Size 2.2 x 2.4 x 2.2m with 17m span. The 1700N IHI COMETS UPS was downrated to 500N for a gentler burn. Ka/S band 3.6m dia dish. At 90E. Kodama was launched in 2002 by H2A. The third apogee firing failed due to oxidizer depletion. RCS firings later got Kodama to GEO at 90.8E.

Carried out the High Speed Data Relay Experiment, 240 Mbit/s; High Accuracy Acquisition and Tracking Tech Expt., for onboard acquisition of the satellites that DRTS relays from and to; and the Communications Network Experiment, with time allocation methods on user satellites. Kodama relayed some Earth images from Midori-II; after that satellite failed, Kodama had to wait for the launch of Daichi.

Insat 3C

 2002-002A


Mass 2750 kg launch, 1050 kg dry. Size 2.8 x 1.7 x 2.0 m with 15.4 m span. This was the last planned Ariane 42L launch, and used a trajectory with a high initial perigee of 570 km. 3C will be placed at 74E.

Insat 3C was colcated with Kalpana 1 at 74E.
