Re: cateva intrebari despre misiune

-----------------------------------

1.ground station concept, coverage, data system, antenna controling and satellite tracking system
2.MCS type, TM rate,TM decomutation, DB concept,data visualization&interpretation, system integration and testing (EGSE)
3.control center equipment:data transfer,redundancy concept, security etc
4.payload:camera?!which type,operating conditions,data rate,characteristics
5.satellite design:
-procesor/main board/data bus 
-memory type
-redundancy concept i.e.backup hardware/sw
-safety concept at least at SW level (FDIR,monitoring entries)
-operating system (basic SW)
-electromagnetic insulation (low earth orbit!)
-quality of electronics assembling i.e clean rooms?!
6.attitude control concept
-stabilization of the platform (which type, how)
-safe mode concept (essential for small platforms)
-which others AOCS modes exists
-autonomous transitions?
-eclipse influence
-influence of spining over TX
-influence of spining over instrument capabilities i.e. camera needs a maximum spining rate for data aquisition
-influence of spining over the power subsystem (i.e study over the power fluctuation)
7.power subsystem
-which type of battery, life time
-eclipse influence for battery 
8.TM/TTC subsystem
-receiver type
-uplink rate
-downlink rate
-TM & TC concept i.e packetization/de-packetization, on board data base concept
Nu cumva toate astea sunt demult descoperite, verificate si incercate si tu citezi din manualul de clasa a I-a a lui NASA sau JPL :D
