Abstract
The Air Force Research Laboratory (AFRL) Space Vehicles Directorate
has developed the Demonstration and Science Experiments (DSX)
mission to research technologies needed to significantly advance
Department of Defense (DoD) capability to operate spacecraft in the
harsh radiation environment of medium-earth orbits (MEO). The ability
to operate effectively in the MEO environment significantly increases the
DoD’s capability to field space systems that provide persistent global
targeting-grade space surveillance, high-speed satellite-based
communication, lower-cost GPS navigation, and protection from space
weather on a responsive satellite platform. The three DSX experiments
areas are:
1. Wave Particle Interaction Experiment (WPIx): Researching the
physics of very-low-frequency (VLF) transmissions in the
magnetosphere and characterizing the feasibility of natural and manmade
VLF waves to reduce space radiation;
2. Space Weather Experiment (SWx): Characterizing and modeling the
space radiation environment in MEO, an orbital regime attractive for
future DoD and commercial missions;
3. Space Environmental Effects (SFx): Researching and characterizing
the space weather effects on spacecraft electronics and materials.
DSX uses a modular design that allows for launch either as a primary
satellite on a conventional launcher, such as a Minotaur, or as a
secondary payload on a larger rocket, such as the Evolved Expendable
Launch Vehicle (EELV).
An overview of the DSX spacecraft design, requirements, systems
engineering approach, bus subsystems, payload designs, and experiments
will be described.
