Simulating a complex flight, or one that physically took place, requires careful tuning of each flight stage. Now, with External Ephemeris, you can generate a trajectory directly from external data. This data can come from a real flight or from an externally generated simulated flight. The trajectory, once imported, can use the flight performance analysis built into Aviator, allowing you to quickly and easily evaluate thrust required, load factors, expected fuel usage, and other parameters.Įnhanced Python Support for Astrogator Trajectory Design You can evaluate your designs against planned trajectories, as well as upload your own trajectory file. With this latest release of STK, Aviator introduces a new procedure in which you can reference external trajectory data while still allowing Aviator to apply appropriate attitude, aerodynamic, propulsion, and thermal models. It is common for engineers to have access to representative trajectory data from real-world operations, simulated trajectories, or other tools that may be used in their design toolchain. Procedures are used to represent different operations of an aircraft’s flight, such as takeoffs and landings, en route waypoints, common holding patterns, and other performance-constrained procedures used to create realistic flight profiles. This feature lets EOIR users directly integrate the thermal load model without needing to export a report, load it in Microsoft Excel, massage and reformat the data, and import it back into EOIR.Ĭreate Aviator Procedures from External Position Ephemeris FilesĪviator provides a flexible, procedure-oriented approach for mission designers to configure realistic aircraft routes. For instance, with aircraft objects, the EOIR shape definitions now enable you to directly link to an aircraft target object’s thermal load as produced by Aviator’s flight modeling capability. This capability also permits any future temperature data providers or potential scalar calculations that could generate temperature values to be used by EOIR directly. It includes both Aviator data providers for aircraft and missiles and passive thermal models for satellites and missiles from STK’s Space Environment Effects Tool (SEET). This release of STK introduces a new feature for STK’s electro-optical/infrared (EOIR) capability: pointing to data providers for temperatures. Sensor system designers need to accurately simulate conditions under which their sensors will be expected to operate and perform. Integrated Electro-Optical/Infrared Thermal Model This reduces the complexity in defining radar clutter and provides additional modeling flexibility by allowing clutter sources to support multiple scattering definitions. These clutter definition models can now also be defined as centralized components through the STK Component Browser so that other modeled systems can easily reference them. In addition, you can introduce a list of clutter sources to be included and considered by the radar system. This update enables you to define clutter source locations and the scattering properties of the geometry. With this latest release, STK’s approach to incorporating and modeling radar clutter effects has been consolidated to make it easier for you to introduce clutter effects and consider their impacts on your modeled radar’s performance. STK provides engineers with the ability to model radar systems, target objects, and other environmental artifacts to understand a radar’s anticipated performance and capabilities. Buildings, trees, and even the ocean’s surface can reflect energy back to a radar’s receiver and produce an effect known as clutter. Radar systems must consider different forms of radio frequency (RF) signal return, such as interference from intentional or unintentional sources or energy reflected from unintended targets.
