A CASE STUDY: Riverside Research Uses STK Components for Web-Based Collection Feasibility

Web-Based Environment Provides Reports for Space-Based Remote Sensing Systems

Solution | SSA/ISR


Develop a web-based community feasibility environment that performs hyper-realistic satellite/sensor modeling, target modeling and collection visualization for complex satellites and constellations based on user-defined collection requirements.


Riverside Research uses AGI’s STK Components software in its Enterprise Collection Research Tool (eCRT) to model and display sensors, analyze terrain impact and field of view, perform intervisibility calculations, determine vehicle position and compute acquisition times.


eCRT uses STK Components to create accurate textual and 4D immersive collection feasibility reports for space-based remote sensing systems. The extensive application programming interface gives users full access to the computational, analytical, and visualization capabilities of STK.

Riverside Research, an independent, not-for-profit organization, provides high-level technical advisory and engineering support to government organizations, public agencies and private subcontractors in the national security and intelligence sectors. Seeing the need for a web-based environment that would enable the space-based remote sensing community to collaborate on collection feasibility, Riverside Research developed the Enterprise Collection Research Tool (eCRT) through the company’s Modeling and Application Development Laboratory (MAD Lab). eCRT uses STK Components to provide AGI software capabilities including modeling and displaying sensors, analyzing terrain impact and field of view, performing intervisibility calculations, determining vehicle position and computing acquisition times.

eCRT users can perform collection feasibility research for submitted (existing) or research (notional) collection requirements. eCRT provides accurate textual and graphical collection feasibility reports by accounting for collection and illumination geometry, ground sample distance, environmental thresholds and other factors. These calculations can be used to tailor existing or future nominations to capitalize on the system capabilities. The extensive application programming interface gives users full access to the computational, analytical and visualization capabilities of STK.

eCRT was recently enhanced by integrating another extensible web-based application, known as CHRONICLE, into the tool. Designed by the MAD Lab under an Independent Research and Development (IR&D) project, CHRONICLE allows users to quickly search past collections and identify those images that encompass a specified search point or overlap a search box. Thus, before submitting a new requirement, users can easily find and review past collections in the target area of interest.

Near-term enhancements to eCRT include supporting feasibility research and submitting collection requirements from a mobile device. Using the mobile device’s location, eCRT will calculate acquisition opportunities, assess schedule competition and ultimately plan the collection.
