Creotech Instruments Creates Next-Generation Microsatellites with Multiphysics Simulation

Creotech implements leading-edge methodologies developed by the European Space Agency to design, assemble and integrate critical equipment that meets space standards.

Satellite Simulation
"Ansys multiphysics tools provide a highly integrated environment and have greatly improved the speed and affordability for developing our new HyperSat microsatellite platform."
— Tomasz Zawistowski Project Manager / HyperSat Creotech Instruments / Piaseczno, Poland

Repairing orbiting microsatellites is impossible due to extreme logistical challenges. Satellite engineers must ensure that equipment is space-proven and extremely reliable before launch. Creating individual satellite components generates high costs, requiring satellite integrators to meet stringent design requirements and satisfy high production process standards. Creotech Instruments’ use of multiphysics simulation effectively addresses these complex challenges.

Electromagnetic Losses with Thermal Coupling For Temperature-Dependent Antenna Performance Assessment (Icepak & HFSS)
Ensuring the thermal stability of antenna-enabled 5G infrastructure, automotive radar, IoT devices and mobile electronic devices is critical in producing expected behavior. Power hungry activity such as video calls, online-based games or varying environmental conditions causes significant swings in device temperatures. If a phone’s battery becomes too hot, it can lose charge or even create safety issues. Also, high temperatures can affect other electronic components within a phone and impact RF antenna performance. Breakdown of a phone’s connectivity with mobile carriers, Bluetooth or Wi-Fi is traceable to thermal problems. You can predict these issues before you build the hardware by simulating your design using Ansys tools. For example, electrical engineers can dynamically link Ansys HFSS and Ansys Icepak in the Electronics Desktop to simulate the temperature of the antenna. Based on the electromagnetic and thermal coupling solutions, they can modify antenna design and predict antenna efficiency and the overall thermal and EM performance of the product. These EM and thermal simulations help to improve wireless communications, boost signal coverage and maintain connectivity for antenna-enabled systems.
Board-Level Electrothermal Coupling (Icepak and SIwave)
Even a marginal rise in temperature can affect the performance and reliability of electronic components, leading to system-wide problems. Board-level power integrity simulations within SIwave can be combined with Icepak thermal simulations to get a complete picture of a PCB’s electrothermal performance. SIwave and Icepak automatically exchange DC power and temperature data to calculate Joule heating losses within PCBs and packages to obtain highly accurate temperature field and resistive loss distributions. These DC electrothermal solutions let you manage the heat produced by your designs and predict thermal performance and safe operating temperatures of chips, packages and boards.

Application Brief

Thermal Solutions for 3D IC Packages and System

3D IC thermal analysis involves tiny features in chips, the package surrounding the chips, and the board or system connecting and surrounding the package. Since they are all thermally coupled, neglecting or oversimplifying one of the components can lead to inaccurate chip temperature prediction.
