RFBR: Radio Frequency Beacon Receiver
No full textThe Space Dynamics Laboratory at Utah State University (SDL/USU), the Air Force Space and Missile Systems Center (SMC), and the Air Force Research Laboratory (AFRL) have teamed together to provide a portable ground-based radio frequency beacon receiver (RFBR) system capable of characterizing ionospheric parameters, including total electron content (TEC), amplitude, and phase scintillation. The system, derived almost entirely of COTS parts, can be configured to receive RF beacons such as those transmitted by existing on-orbit Coherent Electromagnetic Radio Tomography (CERTO) instrumentation, the upcoming Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC2), or other frequencies from VHF to S-band. By monitoring the effects of the ionosphere on multiple space originating RF beacons, characterizing parameters can be derived which can then be ingested into assimilative models to improve ionospheric specification and to estimate ionosphere-induced degradation of communication/navigation signals across the electromagnetic spectrum
GR: Geospatial Reality
No full textThe Space Dynamics Laboratory developed Geospatial Reality (GR), a Government-owned, open software architecture that enhances military/DoD system capability by visually presenting warfighters with tactically relevant, geospatial situational awareness information in real time. GR is designed to facilitate both real-time Augmented Reality (AR) and Virtual Reality (VR) applications on a variety of systems. Most of the underlying software methods are typically the same for both AR and VR and often the location of the operator is the only difference between the two
Iris: Deep Space Small Satellite Radio
No full textWith nanosatellites being used for deep space missions, the need for a unique communications architecture to relay valuable mission data back to NASA’s Deep Space Network (DSN) is vital
Agile in Orbit: Enabling Our Mission Partners to Thrive in the Ever-Changing Space Domain
No full textAt SDL, agility is a quality of both our mission approach and our space architecture
NOVA Test Facility: NanoSat Operation Verification & Assessment Test Facility
No full textThe Space Dynamics Laboratory’s (SDL) advanced NOVA test facility characterizes and verifies subsystem and system performance of small satellites up to 12 kg. The NOVA test facility provides testing to reduce preflight risk and verify requirements and is designed specifically for CubeSat-sized components and systems. NOVA augments SDL’s manufacturing, environmental testing, and calibration facilities, offering comprehensive testing capabilities and expertise for this class of small satellites
Radiation Hardness Drivers for Mission Success – What We Have Learned
No full textRHA consists of all activities undertaken to ensure that the electronics and materials of a space system perform to their design specifications throughout exposure to the mission space environmen
Raditation Test Report: Characterization of Fairchild Imaging CIS2521 CMOS Focal Plane Array
No full textThis report documents the results of radiation testing of Fairchild CIS2521 CMOS imaging sensor. Proton radiation measurements (both transient and total ionizing dose) were performed at the Crocker Nuclear Laboratory (CNL) of the University of California, Davis (UC Davis). Latchup characterization using Heavy Ion radiation was performed at the Texas A&M University Cyclotron Institute, Radiation Effects Facility
Calibration & Testing
No full textWHY CALIBRATE?
Once you have designed and built a sensor, it is essential that you calibrate it—especially when it comes to space instruments. Calibration is the only way to translate your raw sensor data into scientific units that can be analyzed for vital information. Science can only occur when you have calibrated data.
In addition, calibration helps you verify that your sensor meets the requirements and helps to identify performance issues under operational conditions before you fly. Thorough calibration testing before deployment significantly increases the probability of mission success
Pearl: Spacecraft Platform
No full textSDL’s Pearl spacecraft platform delivers the performance, reliability, and mission flexibility needed for demanding small satellite missions. The Pearl platform architecture draws from common sets of components to build 3U, 6U, 12U, and custom sizes with variations in mission capability, parts quality, and radiation tolerance. This flexibility enables our professional staff to develop systems specific to each mission while drawing on a common design to maintain reliability and costs
NSGT: Software-Defined Nanosatellite Ground Transceiver
No full textGround station operators need an affordable, configurable solution to communicate with small satellite radios.
SDL’s software-defined nanosatellite ground transceiver is low cost and highly configurable. It is compatible with a broad range of industry radios, including SDL’s Cadet U and Cadet PLUS.
The nanosatellite ground transceiver can also be used for benchtop testing during spacecraft integration
