Established in 2008, Piesat Information Technology Co., Ltd. (Stock code: 688066), is a domestically leadingsatellite internet company and among the first companies listed on the Sci-Tech innovation Board. The company hasdeveloped PlE (Pixel Information Expert), an integrated software of remote sensing and geographic information withcompletely independent intellectual property rights, and launched PlE-Engine, China's first remote sensing andgeographic information cloud service platform. They serve as domestic alternatives to foundational software ofremote sensing. The company has also constructed the Nüwa Constellation, China's largest multi-layer, multi-modehybrid remote sensing satelite constellation and expanded its business across the entire satelite industry chain, Additionally, it has built a nationwide unmanned aerial vehicle (UAV) production and service system, performingspace-sky-ground" integrated service. The company provides government sectors, enterprises, colleges, and othelrelevant departments with comprehensive solutions for spatial information applications, such as foundational softwareproducts, system design and development, and remote sensing cloud services.

The navigation simulation platform serves as an integrated simulation of the sky, the space, and the ground. ltenables satelite-level simulations such as orbit and satelite clock errors, space-level simulations such as troposphericand ionospheric delays, and ground-level simulations such as observation data and receiver clock errors. lt alsosuppo-rts lations of three-dimensional models, military operations, and target trajectories. The platform is applicableto driling guidance, training evaluation, and simulation deduction in special scenarios. lt is capable of simulatingbattlefield environments and visual and electromagnetic coverage. Additionally, it supports simulations on RDSscoverage, ground station and satellite complementary network analysis, power enhancement, and navigation countermeasure.
