MRAM offers the space industry the speed of SRAM, a density approaching DRAM, the non-volatility of flash memory, unlimited read/write endurance and low power consumption. These on-board storage benefits will enable new use cases for satellite applications.
Your customer wants tested hardware next month and you have budget for a single PCB spin: before sending your ODB++ or Gerber artwork, there are important Design-for-Manufacturing (DFM) checks to ensure your layout complies with formal standards, the fabricator can make it and your new bare-board is returned right-first-time. There are also Design-for-Assembly (DFA) checks to verify your sub-contractor can reliably place parts onto the PCB - I will not sign-off a new build until DFM and DFA have passed!
Covid-enforced production stops of raw materials, the soaring demand for work-from-home and home-learning devices, and the continued growth of the space market, has resulted in supply-chain issues such as component shortages, 70-week lead-times, higher prices and postponed launches.

Global population is predicted to increase to almost ten billion people by 2050 requiring food production to increase by 70%. At the same time, the amount of land available to grow crops is declining rapidly. Learn how satellite technology is enabling smart agriculture.
Many satellite and spacecraft OEMs around the world are looking for ITAR/EAR-free, rad-hard, ultra deep-submicron FPGAs. Discover how, BRAVE, a new family of European rad-hard FPGAs, addresses this market need.
Satellite manufacturers are designing and making proprietary isolated DC-DCs and switching point-of-loads. Learn how magnetics, power transformers and inductors, are fundamental to the design of these voltage regulators.
Integrating GSPS ADCs and DACs with Xilinx's programmable MPSoC fabric reduces physical footprint and chip-to-chip latency, completely eliminating the external digital interfaces between the mixed-signal convertors and the FPGA. RFSoC will enable the next generation of ground-segment electronics.
With so much emphasis on low cost, many spacecraft manufacturers are making their own voltage regulators using space-grade or COTS-based discrete components. Discover how to make your own low-cost DC-DCs for your next satellite.
To enable the next generation of satellite applications, OEMs need to exploit the latest ADC and DACs. However, these need to be powered and clocked properly to deliver their specified performance. Learn how to extract maximum performance from your space-grade ADCs and DACs.
Low-cost COTS components are being used successfully in space: their use requires careful risk assessment and their operation and/or specification may have to be modified or de-rated to meet your mission's reliability needs.
Today, there are six major suppliers of qualified, radiation-hardened, isolated DC-DCs which convert the power bus to an intermediate voltage for input to POLs. Which part is right for your next project?
Today, there are ten suppliers of qualified, radiation-hardened, non-isolated, switching POLs for you to choose from. Which part is right for your next project? Vendors will say theirs is the most suitable and the best POL to power your loads.
Poor PCB layout, inadequate floor-planning, ineffective de-coupling, and weak filtering cause AC noise, interference and transients on the power rails supplying space-grade FPGAs, ADCs, and DACs, impacting their performance. Learn how you can you identify the root causes and how bad they are?
Given that our lives depend on the reliability of ARM-based fail-safe systems every day, can the space industry also benefit from the performance, power, size, ease of use, and accessibility benefits of the ARM architecture?
As SERDES bit rates increase, spacecraft OEMs are grappling with how to measure and characterise the performance and reliability of hardware high-speed serial links to ensure satellite sub-systems are developed right-first time.
To deliver the next generation of satellite services, spacecraft operators are increasingly using larger bandwidths at higher frequencies. Characterising transponder performance such as SNR, BER, SFDR and flatness over hundreds of MHz or several GHz, can be very difficult for OEMs and equally challenging for suppliers of test and measurement equipment.
To support the development of high-throughput payloads, satellite manufacturers are exploiting the benefits of high-speed serial links to connect multiple FPGAs/ASICs on a single PCB and/or transfer data between modules. As bit rates increase, spacecraft OEMs are grappling with how to verify signal integrity and assess the performance and reliability of SERDES channels to ensure sub-systems are developed right-first time.
FPGAs are increasingly being used in almost every spacecraft sub-system and designers now have a choice of process technologies and diverse fabrics. Which one is right for your next mission?
