Hardware verification, testing and validation

Design in any discipline – electronics, mechanical, aerospace, etc. – begins with a specification that captures what the end product should do and essentially drives the entire development cycle.  Verification is intended to check that a product, service, or system meets a set of design specifications. Validation is intended to …

Product Requirements Document (PRD)

The Product Requirements Document or PRD describes all aspects of a new idea required or desired to make its realization a success. The PRD is the bridge between the often vague project briefing and the highly detailed engineering implementation plan. It is also known as the Program Of Requirements (POR), …

Ultra accurate Optical clocks to enable GPS with centimeter-level location accuracy and distributed engagement and surveillance DOD architecture

Phones and other GPS-enabled devices pinpoint your location on Earth by contacting at least four satellites bearing atomic clocks. Each of these satellites provides a time stamp, and the system calculates your location based on the relative differences among those times. The accuracy of GPS Navigation is primary degraded due …

DARPA ROCkN optical atomic clocks will enable multidomain synchronization among various platforms, multi vehicle swarms

Synchronizing modern electronic systems such as the Internet and GPS navigation is currently done using microwave atomic clocks that measure time based on the frequency of natural vibrations of cesium atoms. Those vibrations occur at microwave frequencies that can easily be used in electronic systems.   Optical atomic clocks will …

Digital Signal Processing (DSP) algorithms and Digital Signal Processors

Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. Signals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be …

Model-Based Systems Engineering (MBSE) for Satellites and Aerospace

A system is defined by NASA as  a construct or collection of different elements that together produce results not obtainable by the elements alone. Systems Engineering (SE) is defined as: The process by which a customer’s needs are satisfied through the conceptualization, design, modeling, testing, implementation, and operation of a …
