衛星任務保證

<p><b>Overview</b></p> <p>&nbsp;</p> <p>Every step in the path to new satellite development is crucial — from design and simulation to verification and manufacturing through deployment. Keysight will help you accelerate the speed of design, test, and manufacturing while maintaining a high quality of service and low risk profiles. From guidance and power systems to satellite payloads and microwave communications, our design and validation tools provide greater assurance that your satellite and its subsystems will work the first time, every time. Keysight leverages its experience and expertise, together with its Hewlett-Packard and Agilent legacy, to produce worldclass hardware, software, and custom measurement solutions for your space applications. We continue to build on Hewlett-Packard’s heritage of innovation in the space industry, which began with the Apollo program, to innovate for today’s agile, fast-paced, and vibrant NewSpace economy. Keysight is more than a measurement company. We are trusted hardware, innovative software, and a global network of experts focused on your mission success. <a href="https://www.keysight.com/us/en/industries/aerospace-defense/elevate-your-space-and-satellite-workflow.html">keysight.com/find/satellite</a></p> <p>&nbsp;</p> <p><b>Simulation Ensures Success&nbsp; from Planning to Operations</b></p> <p>&nbsp;</p> <p>Satellite missions operate with a unique set of link budget obstacles. Those challenges include Doppler shifts, atmospheric distortion, latency, extreme temperature fluctuations, high-power levels driving amplifiers into nonlinear regions, and the unforgiving nature of being in space. There are no second chances for a satellite to work. Take extra care in every stage of the design, manufacturing, and deployment process to ensure that a satellite works the first time, every time. Digital modeling of satellite communications systems in these dynamic environments reduces design time and expedites manufacturing while increasing the probability of mission success and lowering production costs. You can integrate Keysight’s PathWave System Design (SystemVue) electronic system-level (ESL) design software with AGI’s System Tool Kit (STK) software, allowing engineers to accurately simulate and validate their signals in the dynamic space environment.</p> <p>&nbsp;</p> <p>• PathWave System Design with STK is an integrated solution for creating a true, mission-level, digital twin used in the digital mission engineering lifecycle.</p> <p>• The solution uses PathWave System Design’s high-fidelity radiofrequency (RF) impairment and channel models to permit user control of STK assets from PathWave System Design simulations.</p> <p>• Perform a broad set of trade studies on satellite subsystems and payloads through a model-based design with integrated mission kinematics.</p> <p>• The PathWave System Design and STK integrated virtual platform provides coverage analysis using actual standards-compliant modulated sources. Analysis includes all mission dynamics with various receiver architectures.</p> <p>• Continually improve simulations by using Keysight’s high-fidelity measurement data to enhance and refine system models.</p> <p>&nbsp;</p> <p><b>High-Fidelity System-Level Design Using PathWave System Design</b></p> <p>&nbsp;</p> <p>PathWave System Design is a multidomain modeling implementation and verification cockpit for ESL design. It allows system architects and algorithm developers to cross traditional baseband and RF boundaries to innovate the physical layer of next-generation aerospace/defense and satellite communications systems. PathWave System Design simplifies tasks by integrating popular digital signal processing (DSP) modeling and implementation interfaces, along with accurate RF electronic design automation (EDA) tools, standards/intellectual property (IP) references, and test and measurement links into a single, highly productive environment.</p>

提升功率水準精確度測量

<p>By 2025, every new car on the road will talk with other cars, exchanging data and alerting drivers to potential collisions. The impact of wireless advancements in homes, businesses, and the military continues to accelerate. The wireless technology evolution demands higher product reliability and greater coverage in an increasingly crowded radio-frequency (RF) environment. The need for greater test accuracy and lower measurement risk intensifies as higher data rates, wider bandwidths, and higher frequency bands drive design requirements.<br> </p> <p>&nbsp;</p> <p>As noise increases at higher frequencies and with wider bandwidths, so does the demand for more accurate, precise, and repeatable measurements. New technologies generate the need for tighter product specifications. Design teams need to test their products with greater accuracy, precision, and repeatability.<br> </p> <p>&nbsp;</p> <p>It is imperative to accurately capture the intended signal in a crowded RF environment with enough signal strength to cover the required distance. The companies who meet this technical challenge will maintain a strong position in the wireless receiver market.&nbsp;<br> </p>

測試準確度入門

<p><b>For 77% of companies, tighter tolerances, manufacturing complexity, and more demanding customer requirements make product quality harder to achieve.</b></p> <p>The risk of inaccurate product testing is immense. Whether your product is a microchip or a large satellite, accuracy, and repeatability are critical to your technical and business success. Test ensures that you meet your product quality standards. Accurate test measurements minimize risk and maximize business returns. Those measurements rely on your test strategy, which comprises three areas:</p> <ul> <li>test system design</li> <li>test system performance — accuracy and repeatability</li> <li>test system operation</li> </ul> <p>Test risk could lead to a missed market window opportunity, product recalls, damage to your company’s reputation, and missed earnings. A solid test strategy is one of the most powerful tools for lowering risk. Accurate test equipment performance ensures that your products meet their intended specifications and yield targets.</p> <p>Calibration is key to test equipment accuracy and repeatability. Yet 92% of companies experienced a product recall, increased returns, or lost yield from test equipment that was out of calibration.</p>
