Canadian STK Case Study – Calculating Satellite Sensor Coverage to Optimize Viewing Opportunities

Canadian STK Case Study – Calculating Satellite Sensor Coverage to Optimize Viewing Opportunities

There is no doubt that the number of space systems has been steadily increasing over the past decade, and it is anticipated that hundreds to thousands will be added in the coming decade. A great majority of these systems will be Earth Observation (EO) satellites that are able to sense or take images of the planet via sensors such as cameras and radars. More specifically, they will be able to sense emitted or reflected energy from the ultraviolet to the visible and into the microwave spectrum. This is because the sensed energy can reveal different aspects about the scene under observation, and these aspects can translate into information on which subsequent decisions or actions might be made.


DRDC has developed a Multi-Sensor Acquisition Planning Tool

The coming glut of space-borne systems is both a benefit and a challenge to many organizations as they work to obtain the best benefit from them while reducing the cost to access them. Defence Research and Development Canada (DRDC) has been working for years to develop a multi-sensor acquisition planning tool with which they can compare various sensor/image-taking opportunities and determine which ones would best meet their acquisition needs.

DRDC has been leveraging STK, and in particular, STK Coverage in order to view, calculate and compare several sensor viewing opportunities to further their research into this operational problem. STK has a proven record of being able to integrate with other applications and data to enrich analysis and help solve sensor planning challenges. AGI worked with DRDC to put together a case study on this activity and it can be accessed here.

Unlocking Data Providers to Counter Unmanned Systems


(The Front Lines) – In the war against the unknown to which the power of modeling, simulation and analysis (MS&A) can be brought to bear, it is often helpful to be able to access, manipulate and leverage existing data in order to generate new insights into the operational problem. Take the increasingly important mission of countering unmanned systems – a product of the widespread proliferation and application of said systems – their capabilities now make them such that serious consideration must be made to limit or negate their effectiveness. This can span from kinetic (‘blow ’em out of the sky’) to passive (jamming/interfering with their control signals). With Systems Toolkit, it is trivial to quickly model an enemy unmanned aerial system (UAS) with a communications receiver, as well as both friendly static and moving transmission systems. The latter systems can then be set up at potential interferers such that their energy can overcome or jam the enemy UAS’ receiver.

EnemyUASComboAnother possible way to look at this type of scenario is to combine both the electromagnetic ‘access’ of the jamming transmitters to their target, and a specified ‘kill zone’ range interval. By accounting for the kind of transmitter system, available environment, rain and radio-frequency models, terrain, and object motion, STK is pretty good at identifying the likely jamming intervals for a given scenario. Via the Analysis Workbench Module (AWB) module, it is also possible to establish both a range profile for the enemy UAS with respect to the jammers, and to set a condition that specifies the range intervals of ‘interest’ to which the jammers may or must respond. The data for the specific dynamic ranges are ‘inherent’ to the STK scenario and thus via STK AWB, that information can be brought forward into the analysis to gain new insights into the mission.

This and similar aspects of STK AWB are covered during STKCore(TM) Training, with the next serial taking place 12-14 September, 2017, in Ottawa. Earlybird rates are available until mid-August. Click here to register.

DRDC S&T Announces All Domain Situational Awareness (ADSA) Program

DRDC S&T Announces All Domain Situational Awareness (ADSA) Program

Although its Letter of Interest (LOI) request has been out for a couple of days, senior members of Defence Research and Development Canada (DRDC) took the opportunity of the CADSI Military Outlooks to advertise this new $133M program (over 5 years) to industry and government partners. It has a particular focus on conducting R&D for continental surveillance, and in particular the Arctic.

The attached video describes a Modeling, Simulation and Analysis approach to examining the capabilities and effects of several possible surveillance assets such as satellites and UAVs, as well as analyzing their possible communications links.  Systems Toolkit (STK)® is particularly adept at analyzing system of systems, sensor mixes and performing trade-off analyses of options. You can contact Wayne Ellis at for more information about the capabilities of STK®.
