From: "Alberto E. Zagni" Date: 18:43, 27 Nov 2006 Mineo and Mike, thank you very much for your reports of reception and decoding of ITAMSAT IO-26 after 13+ years in orbit! The spacecraft is in SAFE mode (MBL) and is trasmitting a limited number of telemetry channels. The equations Mike is referring, to are those trasmitted by IHT high level software, currently not operational. If anybody is interested I can pass the equations and channels valid in MBL mode. Any reception report is welcome! Alberto I2KBD ITAMSAT Mission Director ----------------------------------------------------------------------- http://www.asahi-net.or.jp/~ei7m-wkt/numbr522.htm
