The following is a statement from NASA acting Administrator Robert Lightfoot on President Trump signing Tuesday the National Aeronautics and Space Administration Transition Authorization Act of 2017:


“We would like to thank President Trump for his support of the agency in signing the National Aeronautics and Space Administration Transition Authorization Act of 2017.


“We also want to express our gratitude to a bipartisan Congress for its thoughtful consideration of the agency’s path forward. We are grateful for the longstanding support and trust of the American people, which enables our nation’s space, aeronautics, science, and technology development programs to thrive.


“Our workforce has proven time and again that it can meet any challenge, and the continuing support for NASA ensures our nation’s space program will remain the world’s leader in pioneering new frontiers in exploration, innovation, and scientific achievement.”

ADATS Could Assist X-planes With Large, Super-Fast Data Transmission

A network and communication architecture that can more efficiently move data from research aircraft, while using half the bandwidth of traditional methods, could eventually also enable data collection of precise measurements needed for testing the next generation of X-planes.


Called the Advanced Data Acquisition and Telemetry System, or ADATS, researchers at NASA Armstrong Flight Research Center in California integrated the new systems into a NASA King Air recently for a series of three flights following extensive ground testing. The new system can move 40 megabits per second, which is the equivalent of streaming eight high-definition movies from an online service each second, said Otto Schnarr, principal investigator.


Researchers aren’t looking to make binge watching easier – they are interested in the system’s speed in moving large amounts of data up to four times faster than previous network-based telemetry efforts and up to 10 times faster than current systems Armstrong researchers are using, Schnarr explained.


All of this capability is gained without new architecture and using the advanced modulation technique to save spectral bandwidth, time and research dollars, said electrical engineer Matthew Waldersen. In addition, the system allows people to participate in the flight test from wherever a secure network is available. As many as 3.3 million sensor measurements per second can be acquired, or a focused data set can be targeted to free up bandwidth for other tasks, like streaming high-definition video simultaneously, he added.


ADATS aims to advance flight test data acquisition and telemetry systems using an Ethernet via telemetry subsystem that wirelessly transmits test data and an advanced data acquisition system that allows remote researchers to command experiments and receive data collection during flight.


“The main components are a ground station, a transceiver on the airplane and the instrumentation systems that tie everything together,” said Tom Horn, ADATS project manager. “The tests explored what this system does and how it behaves. We wanted to make sure we understood the nuances and determine if additional testing is required for researchers to feel comfortable using it.”

The flights capped a three-year effort to fill in existing gaps in the technology, such as range, instrumentation and system design challenges. ADATS team members have made well-received presentations at the center that led to additional brainstorming session on potential uses for the technology.


“People were not having trouble coming up with how they could put it to use,” Waldersen explained. “Having more data allows researchers to do what they do better. Everyone at the sessions agreed the technology is worth pursuing. You know a project is a success when you take questions from engineers like, ‘have you considered using it for this case, or could we do this with it?’”


Building up the capability is the next step.


“In any electronics project there is a hardware and a software component,” Waldersen said. “We have completed a lot of work with the hardware component to see what it can do and now it’s a matter of the software aspect and how it integrates with ground operations, which projects will put it to use immediately and what other systems can we build around it to fully utilize the capability.”


Maturing the technology could be useful for upcoming X-plane testing. For example, measurements of airflow data measurement along the entire face of a fan engine could be efficiently researched, Horn explained. Another advantage is unlike traditional data collection that can experience loss of data, or “dropouts,” ADATS can eliminate the loss with this data collection method. However, delays can still occur and researchers are looking into understanding the ramifications of that for safety.

In addition, the system also could have implications for uninhabited air vehicles and systems for uplinks and bandwidth management. For example, aircraft like the Ikhana or Global Hawk could gain efficiencies. ADATS also could work in combination with an Ethernet-based fiber optic sensing system to streamline data collection.


The ADATS effort can be traced back to The Hi-Rate Wireless Airborne Network Demonstration (HIWAND) in 2005, which also flew on the King Air. It demonstrated in flight a network-enhanced telemetry system that enabled connectivity between air and ground, including airborne Internet access. The capability was focused on allowing scientists and others to downlink scientific data and uplink critical information to airborne sensors more efficiently.


NASA’s Flight Demonstrations and Capabilities project, which is part of the Integrated Aviation Systems program, is funding the current effort.
