Case Study
“For a startup like us who has one shot for success, no matter if the world believes in your theory and loves that you want to protect the oceans, it’s still a challenge to get the capital even for a single shot. In order to ensure that you don't fail at this one shot, simulations come to your rescue. So, it's very important to simulate every single thing.”
- Gaurav Seth, Co-founder and CEO of PierSight
Oceans cover about 71% of our planet’s surface, which makes monitoring them incredibly difficult. However, this task is critical in aiding with rapid oil spill detection, exclusive economic zone (EEZ) monitoring, preventing illegal fishing, and more. PierSight aims to achieve the persistent monitoring needed to address these concerns in the maritime industry. To do so, the company uses synthetic aperture radar (SAR) and automatic identification system (AIS) satellites to revolutionize maritime surveillance.

Challenges
While PierSight’s goals are clear, achieving them is no simple endeavor. First, space is a resource-intensive industry that typically involves lengthy design and development periods and large amounts of funding. Gaining the necessary funding with such a long lead time often proves difficult, especially for startup companies. Space is also a ruthless environment. “Even if only a single thing goes wrong, all your good intentions and hard work can be killed by space,” says Seth.

Engineering Solutions
PierSight used Ansys software throughout its design and development process:
- Using HFSS software and the Workbench platform, they designed the antennas used in their spacecraft, including the deployable antenna design that PierSight had already launched.
- The team was able to analyze the antenna performance through simulation before moving on to physical vibration tests.
- They utilized STK software to visualize and analyze the SAR satellite’s thermal performance in space.

Benefits
- The accurate simulation results PierSight received from Ansys software helped the company “gain confidence before a difficult environmental test for space,” says Seth.
- Participating in the Ansys Startup Program enabled PierSight to save costs by receiving simulation software at a discount.
- Simulation helped PierSight successfully launch its technology in the Varuna mission. To achieve this success, the PierSight team used Ansys simulation software to increase efficiency by upskilling their quickly growing team and reducing their development time. For the latter, the satellite PierSight used in the Varuna mission was built in only nine months — an 81.25% decrease in development time compared to the typical industry cycle for creating a SAR prototype.
