Development of a Multi-User Modem for Space Telecommunications

Efficient support of planetary surface missions typically requires an orbiting asset that acts as a relay point to/from Earth. Orbital relay passes are normally 5 to 15 minutes in duration over any specific landed site. When multiple landed assets are co-located or near-located in...

Wire Bonding to Pads in Tilted Planes

Scientific imaging arrays need to have their individual imaging elements arranged in a close-spaced mosaic. The typical single imaging element is a silicon chip mounted on a larger support frame. This excess area of the support frame takes away valuable imaging space from the mosaic. This appears as a grid...

FPGA Reconfiguration with Accelerated Bitstream Relocation

Partial bitstream relocation (PBR) on field programmable gate arrays (FPGAs) is a technique to re-scale parallelism of accelerator architectures at run time and enhance fault tolerance. PBR techniques have focused on reading inactive bitstreams stored in memory, on-chip or off-chip,...

Real-Time LiDAR Signal Processing FPGA Modules

A scanning LiDAR, by its inherent nature, generates a great deal of raw digital data. To generate 3D imagery in real time, the data must be processed as quickly as possible. One method of discerning time-of-flight of a laser pulse for a LiDAR application is correlating a Gaussian pulse with a...

EADIN Lite Communication Network

The distributed engine controls (DEC) task seeks to investigate the capabilities of a distributed network for aircraft engine controls. Traditional aircraft engine control systems use analog systems to communicate with sensors and actuators. The ability to upgrade an engine after manufacture, by swapping out...

Semiconductor Nanomembrane-Based Flight Sensors and Arrays

These sensor arrays can be used to measure skin friction and pressure.

There are two broad classes of methods for measuring skin friction (or wall shear): indirect and direct. The direct methods generally employ a movable element of the actual surface surrounded by a very small...
