- 1. “Nationwide Eclipse BallooningProject Engineering Systems Overview” Randal (Randy) M. Larimer, PE Special Projects Director, Montana Space Grant Consortium NEBP Engineering Presentation December 2022
- 2. Abstract This presentation highlightsthe technical engineering systems used to safely and successfully capture real-time video and data from a high-altitude weather balloon during the October 14, 2023 annular eclipse and the April 8, 2024 total solar eclipse. The engineering POD leads and their students have been carefully designing, documenting and testing the systems that will be distributed to the participating forty engineering teams. System components include an Iridium tracking system, a cutdown system, a tracking ground station, a streaming video system, a dual camera system providing 360 degree views, a helium vent valve system for latex balloons, zero pressure balloons, temperature sensors, pressure sensors and precision GPS sensors. Software to support the system components include a real time tracking website, tracking ground station code, dual camera and streaming code, along with the embedded code. Participating teams will learn the systems and have an opportunity to create their own payload. NEBP Engineering Presentation December 2022

Editor's Notes
- #5 Commit Starting in January 2014 set about convincing NASA to fund the project while still researching how we could do it (internet at 100,000 feet? Too early (Google Loon) or too expensive ($1M communication vans); entered discussions with the FAA (every flight worthy vehicle in this 80 mile wide space in those few minutes!) to see if would even allow it, Thinking about how we’d could handle 50 live HD video streams on a webpage with 50 – 500 million views (NASA estimate) selling it to SGs to work on and pay for their student teams, started Resolution Turns out, with a lot of hard work, we could do it – radio modems; though have to build up all the systems selves; create tracking (Iridium), use local wireless commands (Xbee); each complete system costs about $3,700. Have 47 teams from 31 states, have about $1M in NASA funds – half SMD, half SG
