Error correction, the critical challenge for building large scale fault tolerant quantum computers

‘The development of a “quantum computer” is one of the outstanding technological challenges of the 21st century.  Quantum computers gain their power from the special rules that govern qubits. Unlike classical bits, which have a value of either 0 or 1, qubits can take on an intermediate state called a …

Small Spacecraft Avionics

Small Spacecraft Avionics (SSA) are described as all electronic subsystems, components, instruments, and functional elements included in the spacecraft platform. These include primarily flight sub-elements Command and Data Handling (C&DH), Flight Software (FSW), and other critical flight subsystems, including Payload and Subsystems Avionics (PSA). All must be configurable into specific …

Satellite Electrical Ground Support Equipment (EGSE)

There is growing utilization of miniaturized satellites for military and defense applications.  Defense organizations have been launching communication nanosatellites and microsatellites to provide communication signals to soldiers stationed in remote locations or in dense forests. The military needs more data bandwidth and reliable communications infrastructure for its UAVs, which can …

Raytheon’s AN/SPY-6(V) is and integrated air and missile defense naval radar that can track multiple ballistic and cruise missile targets.

Navies around the world are increasingly facing formidable strategic and threat environments in terms of complexity, lethality, range, sophistication and number of threats. Many of these threats, including long-range anti-ship cruise missiles, can travel hundreds of miles to their targets,  toward surface ships challenged to detect the approaching weapon with …

Safety Analysis tools Failure Mode and Effect Analysis (FMEA) and Fault tree Analysis (FTA) avoid potential error, failure, or defect in mission-critical or safety-critical systems

The design, acquisition, and operation of products and systems intended for defense applications must understandably meet some of the strictest reliability standards of any industry or sector. When it comes to a mission-critical apparatus, failure of any type can lead to unacceptable and devastating consequences. For this reason, the Department …

Satellite Harness Design, Optimization and Standards

Wire harnesses are bundled assemblies of cables and connectors, that are used to transmit signals and power between components. If we could compare a satellite to the human body, the electrical harness would represent the blood vessels conveying the power and the nervous network transmitting the commands and sensor information …

Defense and Aerospace software Verification and Validation

Late delivery or software defects can damage a brand’s reputation — leading to frustrated and lost customers. In extreme cases, a bug or defect can degrade interconnected systems or cause serious malfunctions. Consider Nissan having to recall over 1 million cars due to a software defect in the airbag sensor detectors.  …
