Spacecraft Interface Control Document (ICD)

The definition, management, and control of interfaces are crucial to successful programs or projects. Interface management is a process to assist in controlling product development when efforts are divided among parties (e.g., Government, contractors, geographically diverse technical teams, etc.) and/or to define and maintain compliance among the products that should …

More Electric Aircraft (MEA) and All Electric Aircraft enabled by new technologies

The civil global aviation market has experienced considerable economic growth in recent years and will keep increasing. It is estimated that around 1300 new international airports will be required, and the commercial aircraft fleet will double by 2050, with a projected passenger throughput of 7.2 billion in 2035. This growth …

Satellite types and their Orbits

Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other spacecraft. The motion of these objects is usually calculated from Newton’s laws of motion and law of universal gravitation. Orbital mechanics is a core discipline within space-mission …

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 …

Matlab and Simulink

Modeling is the process of representing a model (e.g., physical, mathematical, or logical representation of a system, entity, phenomenon, or process) which includes its construction and working. This model is similar to a real system, which helps the analyst predict the effect of changes to the system. Simulation of a …
