Public Reports and Presentations
DSES President Dr. Richard Russel has been measuring signal strengths 0f stations in the Very Low Frequency (VLF) band for the past year, looking for changes in ionospheric propagation due to solar flares. He uses a Sudden Ionospheric Disturbance (SID) monitor small radio telescope. His SID detector is located in Colorado Springs, CO. The measurements are sensitive to the changes in radio propagation at sunrise and sunset.
With his baseline of historical data at sunrise and sunset, he then predicted what could be expected during the August 20, 2017 solar eclipse. He presented his prediction work at the 2017 Society of Amateur Radio Astronomers Annual Conference at NRAO Greenbank, WV on July 25, 2017. His paper was titled, “Ionospheric Reflection Variation During Sunrise and Sunset and Predictions for the 2017 Total Eclipse”.
During the eclipse he made measurements, and found the results matched closely with his predictions. The link presents a summary of his work. Plus it has YouTube links to this and another of his talks at the SARA conference. The second talk is titled, “The Use of Monte-Carlo Analysis to Evaluate Radio Astronomy Source Detection”.

Ray Uberbecken presented “Using High Power FM stations to Monitor Meteor Activity Utilizing the 19-kHz Pilot Carrier” at the 2017 Central States VHF Society Conference in Albuquerque, NM. Conference (Dates: July 27 – 30, 2017). Ray’s topic is about an original engineering design and technique he developed for meteor scatter, This approach can replace using broadcast analog TV signals, most of which now are gone.

Deep Space Exploration Society 2016 Highlights
- Galactic Navigation Position Data Using Interstellar Medium HI Velocity Measurements, Dr. Richard Russel. SARA Western Conference – March 23-25, 2018, Stanford University, Palo Alto, CA.
- Abstract: This paper explores the use of HI Doppler measurements as an aid to galactic navigation. Historic HI measurements of the Milky Way are used to determine the galactic rotation rate. The location of the interstellar medium producing the HI signals can then be calculated. Knowing the location of the HI signals, the HI frequency corrections can be made for a spacecraft moving between two points in the galaxy. This data can then be used to supplement optical, pulsar and other galactic navigational aids.
- Geographically-spaced Synchronized Signal Detection System, by Skip Crilly, SARA Western Conference – March 23-25, 2018, Stanford University, Palo Alto, CA.
- Abstract: A system has been designed and implemented that makes simultaneous geographically-spaced time-and-frequency-synchronized measurements of hypothetical extraterrestrial narrowband signals in the 1405-1448 MHz band. One radio telescope is the Sixty Foot Deep Space Exploration Society Plishner Telescope in Haswell, Colorado, and the second radio telescope is the Forty Foot Telescope in Green Bank, West Virginia. A GPS-signal-locked reference oscillator and a digital back-end is used at each site to permit differential Doppler measurements to a precision of +-1.8 Hz. This presentation will describe the system, observations of simultaneous close-frequency pulses, and future plans to enhance capabilities of the system.
