Modern Approach to Liquid Rocket Engine Development for Microsatellite Launchers

Categories: >

Microsatellites have been carried to space as secondary payloads aboard larger launchers for many years. However, the secondary payload method does not offer the specificity required for modern day demands such as increasingly sophisticated small satellites that have unique orbital and launch-time requirements. Furthermore, to remain competitive the launch cost must be as low as…

Government and IC Program Adoption of Virtualized Small Sat Ground Systems

Categories: >

For a number of years small satellites have been seen as a way to provide low cost solutions for technical demonstrations. Only recently have they been viewed as mission-ready for government and IC programs. While the commercial world has been quicker to adopt these new platforms, government and IC programs have been slower to do…

Satellite Fleet Operations Using a Global Ground Station Network

Categories: >

With the emergence of small satellites and satellite constellations, there have been drastic changes in the overall methodology of satellite operation. Previously, satellite operators tended to operate 1 to 5 satellites using 1 to 3 ground stations. In this newly emerging paradigm, satellite operators will be operating tens to hundreds of satellites using tens of…

Survivability Analysis of a Small Satellite Constellation

Categories: >

Spacecraft are normally designed to survive the numerous natural hazards inherent to spaceflight. Rarely does this process expand to cover defense against human threats. This paper presents a survivability assessment of a generic small satellite constellation and recommends design changes and tactics that will optimize defense while maximizing the preservation of capability. Traditional satellites possess…

Verification Approach for Large, Complex Optical Systems: Lessons from the James Webb Space Telescope

Categories: >

As ever larger and complex optical imaging systems are envisioned, it will become increasingly difficult to perform full-aperture verification of the optical system in the flight configuration as required for the typical “test as you fly” approach.  Full aperture testing is challenging due to both the cost and technical feasibility. As segmented apertures grow larger,…

Protecting Aircraft in Real-Time from a Launch or Re-entry Failure

Categories: >

The growing frequency of launches and re-entries of space vehicles has increased impact on other users of the National Airspace. Because these activities have a relatively high probability of failure, the FAA closes airspace proactively to mitigate the potential impact of debris resulting from a breakup event. The FAA Office of NextGen and Office of…

Cooperative National Airspace: Air Traffic Integration and Situational Awareness

Categories: >

An integrated Space and Air Traffic Management System (SATMS) is one of the key initiatives of the FAA. This goal to achieve an aerospace environment in which space and aviation operations are seamless and integrated in a modernized, efficient National Airspace System (NAS) is a cumbersome and sizeable task; it requires full cooperation from airspace…

An Innovative, High Fidelity Approach to Space Situational Awareness (SSA) Data Simulation

Categories: >

Space Situational Awareness (SSA) is vital to maintaining our Space Superiority. We present an innovative, high fidelity, time-based simulation tool, PROXOR™ (Proximity Operations and Rendering), which supports SSA by generating realistic mission scenarios including sensor frame data with corresponding truth. This is a unique and critical tool for supporting mission architecture studies, new capability (algorithm)…
