Devido ao processo de vaporização de gases, vacumização e uma certa inação do computador de bordo, o satélite por algumas hora deixou de enviar telemetria. No entanto, as 15h00 de Angola do dia 28, foi restabelecido a telemetria com o Angosat.Actualmente decorre a normalização dos seus sistemas e subsistemas e o processo de inserção em órbita. O estado do satélite é considerado óptimo.
Moscow. December 30th. INTERFAX.RU - The problems that arose after the launch of the Angolan communications satellite Angosat were related to the compatibility of Russian and French onboard equipment standards, an informed source told Interfax.[...] After [Angosat] launch, problems arose due to "inconsistencies" between Russian and French regulations, "the source said.He clarified that the satellite has components produced in France, whose compatibility with the Russian standards has created difficulties. "The problem was solved remotely by a group of young Energia employees, who developed the spacecraft," the source said.
Unfortunately, Fregat upper stage (2017-086B) from the 26 Dec AngoSat 1 launch left in an orbit infringing upon GEO Protected Region--perigee only 92 km above GEO. #SpaceDebris (graphic-ECR frame depicting 10 days of the Fregat orbit). lnkd.in/difEp32
In a German forum i found a report, that the problem occurred with a star tracker which have a to high resolution. This makes the buffer overflow....https://www.raumfahrer.net/forum/smf/index.php?topic=14712.75http://www.sodern.com/website/fr/ref/Optroniques_215.html
I'd seen the original "rumor" reported on NK forum, however it was much criticized there so I wasn't sure how credible it is..
Source: Angosat satellite ultimately ceased to function
I think it's true there is no control.Looking at STK plots now, since Dec 29 not a single hint of any manoever. Drifting about 3°W/day, now near 3°E, and inclination increasing steadily.
So apparently the commands to the thrusters sent on January 9 to stop the drift and stabilize at 14.5°E in GEO were never received
