Main computer will be processing images to get direction to a center of the earth. Looks like I'll be not be able to finish that software at a time – in this case CubeSat will fly with basic software allowing communication and transfer data/images only. Main can drain 75mA on 3.3V (for main it is OK). Problem with main I can not control power consumption from inside. Up today only one advantage for main – any source code can be easily ported without headache.

Hi Jenisha
Question that I am interesting based on (page 481 book by Boris Chertok reference http://history.nasa.gov/SP-4110/vol3.pdf in Russian version it is better to read but anyway):
"During Molniya-1’s third and subsequent spaceflights a rapid degradation
of the photovoltaic converters (FEP) was detected.(33) It was the manifestation
of a little known effect of irradiation when passing through near-Earth

Hi Rick,
I can not use any available kits. Bunch of reasons.

February 6, 2012 - by Translation: Report for my friend Alex (Шура) :
Да - забыл сказать, вчера после того как все заснули, я вывел дрейф Гироскопа на ноль - одна из проблем ушла - трюк (кроме как обычно-программистской ошибки) был в следующей математике -
- считаю кватернион за Х секунд (эквивалентно усреднению)
- затем каждые Х секунд прикладываю обратный кватернион
В течении последующих каждых Х секунд значение плавает, а затем происходит прыжок в ноль. Причем значение функции кватерниона между квантовыми скачками - ТРЕХМЕРНАЯ ВОЛНА!!!

. . Yep – forget to tell. Yesterday after everybody fell a sleep, I finally set Gyro’s drift to zero. One problem after two months solved. Trick was (except usual == program’s bug) was in mathematic –
- calculate rotation using quaternion for a period of X seconds (QCorr0);
- then any next X seconds apply to calculated rotation complimentary of original correction (QCorr0)
