About emergency situations with the federal space launch

of communication satellite "Express - MD2"

Bauman Moscow State Technical University, 105005, Russia

Recently there has been an increase of emergency launches of telecommunication satel-

lites and dual purpose satellites. The article investigates the cause of the emergency situ-

ation (ES) with the federal space launch of communication satellite "Express - MD2".

Knowing that the planned in advance launch of the Russian spacecraft has been canceled

due to technical reasons, it is suggested that the new cyclogram was based on the cyclo-

gram-report of the previously successfully launched Canadian satellite «Nimiq- 6". When

matching cyclograms a number of similarities was found.

In the frame of the work the

analysis of the two cyclograms was conducted and the possible error committed in their

translation was calculated. The study revealed a bias of experts at Baikonur, which was a

time mismatch between the on-board time set in the volatile booster clock, and the day-

light saving time, according to which a part of the old spacecraft flight cyclogram calcu-

lations was made. Thus having previously published flight task cyclogram it is possible to

calculate the time of the ES occurrence and its end. To avoid loss of telemetry it is neces-

sary to have the ground (above-water) tracking aids.

Keywords
