A key strategy in the development of STK 9, our most aggressive release since STK 5, was to help users across entire business units or programs maximize productivity. We redesigned interfaces to shrink the upfront STK learning curve and empower engineers to solve complex spatial problems twice as rapidly as before. The enhancements to STK fall into three categories; accessibility to data, usability enhancements, and functionality improvements to specific modules.

STK/Astrogator’s new scripting tool allows you to write a script inside the uI using Javascript or Vbscript that executes any time the segment or profile to which the script is attached is run. for example, you can use the scripting tool to implement the lambert problem solution as an initial guess tool for interplanetary trajectories.

>> You can specify the time of flight desired, STK will compute the planetary positions, and the Scripting Tool will calculate the required delta-V to place the spacecraft on the transfer orbit. <<
