Abstract:

In the aerospace mandate,a high TT&C coverage can provide real-time,continuous,reliable information support.A simulation model of monitoring and control links is established based on VC with STK secondary development.The STK/X module is employed for better display and Access module for calculation and display of the link margin and coverage of the control links.For different ground station deployments,the TT&C of the spacecraft are computed.VC with STK integrated secondary development can greatly decrease the development time of control systems.

Key words: TT C;STK secondary development;STK X;simulation and modeling
