ERAU Advanced ADSB Prototype for Support of Reusable
ERAU: Advanced ADS-B Prototype for Support of Reusable Launch Vehicles and Other Spacecraft • • • PROJECT AT-A-GLANCE AST POC: Nick Demidovich UNIVERSITY: Embry-Riddle Aeronautical University PRINCIPAL INVESTIGATOR: Dr. Richard S. Stansbury STUDENT RESEARCHER: Brandon Neugebauer, Richard P. Day, Alonso Yosvany, and Dominic Tournour RELEVANCE TO COMMERCIAL SPACE INDUSTRY • ADS-B technology provides a means of tracking suborbital reusable launch vehicles both during the ascent and descent providing details including: position, altitude (geodetic and pressure), and velocity. It could reduce the footprint of airspace segregation required for commercial space operations. Goals • Demonstrate UBR-ERAU Advanced ADS-B on Up Aerospace Space. Loft 8 rocket launch (complete) STATUS • Analysis of data from SL-8 data to determine advanced ADS- • Flight demonstration on high-altitude balloon, sounding rocket, and re-entry vehicle prototype B performance (complete) • • Demonstrate UBR-ERAU Advanced ADS-B on Up Aerospace Maturation plan through flights via NASA Flight Opportunities Program and other commercial space stakeholders Space. Loft 11 rocket launch with upgraded GPS antenna • Develop Advanced ADS-B for reentry spacecraft (complete) FUTURE WORK • Continued integration on diverse set of platforms (in progress) • Future flight tests: SL-11, NSC HASS, Virgin. Galactic’s SS 2, and others • Propose follow-on research for LEO operation (in progress) • Propose concepts new ADS-B message format (in progress) • Evaluation of DO-282 B specifications to design new message format for space vehicles • Proposed research to upgrade further for LEO spacecraft COE CST Fifth Annual Technical Meeting (ATM 5)
Maturation through flight opportunities Source: Near Space Corporation Criteria Pass / Fail Comments Broadcasts well-formed messages Pass ITT GBTs and two portable Garmin GDL 90 successfully parsed data Vehicle tracking for 90% of flight Fail 73. 8% of full flight, 80. 5% post-despin, and 95. 9% on descent. Characterization of data loss Pass Primary characterization of data loss was configuration onboard spacecraft and NOT ADS-B unit itself. Correlated with other data sources Pass Utilized truth data from WSMR primary radar. Position/altitude accuracy measured. COE CST Fifth Annual Technical Meeting (ATM 5)
