SYSTEMS TOOL KIT (STK) – Modeling complex land, sea, air, or space systems and evaluate their performance in real or simulated time.

ORBIT DETERMINATION TOOL KIT (ODTK) – ODTK provides orbit determination and orbit analysis support for the entire life cycle of satellites and their tracking systems, processing a wide variety of traditional and non-traditional measurements using a state-of-the-art optimal sequential filter and matched smoother to generate orbits with realistic covariance.

STK ASTROGATOR – Used for interactive spacecraft maneuvers and trajectory design. STK Astrogator allows for finite, impulsive, and optimal finite modeling of complex maneuvers including rendezvous and proximity operations, station keeping, interplanetary, and low thrust.

STK SATPRO – STK SatPro provides a collection of specialized space tools for designing and operating satellite systems.

STK SOLIS – A spacecraft simulation environment in STK used for rapid development, assembly, test, and integration.

STK COMMUNICATIONS – The Communications module is used to model and analyze real-world RF and optical communications.

STK COVERAGE – Coverage analyzes when and how well regions on or above the central body’s surface are covered by a collection of assets based on a user-defined performance criteria.

STK ELECTRO-OPTICAL AND INFRARED (EOIR) – Electro-optical and infrared (EOIR) models detection, tracking and imaging performance of electro-optical and infrared sensors.

STK TEST & EVALUATION TOOL KIT (TETK) – T&E Tool Kit is designed to assist from test plan creation through mission briefing to post-test analysis and verification for flight qualities and mission systems (Radar, EW, EOIR, RF-Com, etc.) across multiple domains including aircraft, satellites, missiles, maritime and ground vehicles, and ground facilities.

STK RADAR – The Radar module provides thorough analysis and graphic displays of radar systems.
