|Sujet: Les sondes lunaires russes avec des ordinateurs équipant les satellites de Reshetnev Mar 16 Oct 2012 - 20:35|| |
Il semble que les prochaines sondes lunaires russes Luna-Glob et Luna-Ressources, fabriquées par NPO Lavochkhine, embarqueront un nouvel ordinateur central et non celui qui a failli sur Phobos-Grunt. Ce serait celui qui équipe les satellites de ISS Reshetnev (Glonass et autres).

Management System Russian lunar vehicles project "Luna-Resource" and "Luna-Glob", which will start after 2015, are radically reshaping - instead inherited from the "Phobos-Grunt" onboard computers will be installed on-board computers that are used in the production of satellite ISS Reshetnev name, told RIA Novosti source in the space industry.
After the loss of the automatic station "Phobos-Grunt" in November 2011, Russian lunar mission plan was scrapped due to the need to improve the reliability of devices that are designed based on the "fobosovskih" developments.
According to the Commission's findings, the cause of the loss of "Phobos" was "local effects of heavy charged particles" on the chip-board computer, which led to the two half-sets simultaneously restart the computer and transfer it in safe mode.
According to the source, now experts Lavochkin, which created the "Phobos", change control system of lunar probes, getting rid of the onboard control complex (SCU), which was identical to the "fobosovskomu" created by the Moscow association "STRC" Technical Committee ".
"(NPO Lavochkin President Viktor) Hart wants to use the SCU, which is placed on the Reshetnev satellite. This is another system with a different system commands is an entirely different product," - said the source.
