(EOSS) is a non-profit organization comprised of individuals interested in the use of high altitude balloon flights to offer an experimental platform for students and other experimenters. The group has a very high level of participation by amateur radio operators, however, this is NOT a requirement for membership and participation. EOSS has flown 14 successful flights over the past few years. We regularly fly amateur television, and a suite of atmospheric sensors. Other experimental payloads have included, GPS and LORAN-C for a comparison of their accuracy. Homebrew differential GPS on the same flight. Students of Coloraro University at Boulder (CU) created their own differential system using a gps receiver at a KNOWN location, and calculated the offsets themselves, allowing the GPS vs. LORAN-C comparison greater accuracy. EOSS hosted last year's "National Balloon Symposium" in Denver Colorado. People from more than 10 states, and Canada were in attendance as well as some of the commercial providers of equipment used in our "hobby". We plan to fly EOSS-15 soon and here is our general information release about this flight. If you have any questions about the flight or EOSS please use email to my address (sig file at bottom). EOSS-15 FLIGHT PROFILE LAUNCH SITE: Thunder Ridge Middle School Picadilly and Smokey Hill Rd. Aurora, Colorado, USA latitude 39.61195 deg North longitude 104.75050 deg West (The lat/lon is actually for a location within 1 mile of launch point. I haven't been to the launch site to take an accruate fix yet.) LAUNCH DATE: February 26,1994 LAUNCH TIME: 1600 UTC (Set up 1400 UTC) Launch time subject to FAA approval ON-BOARD EXPERIMENT: Conducted by Cherry Creek High School. PURPOSE: To measure the various levels of alpha, beta, and gamma radiation at various altitudes. SHUTTLE FREQUENCIES: Packet: 144.340 ATV: 426.250 CW Beacon: 147.555 Carries the call of WB4ETT There will be a HF net run by Sparky\ KA0DPC on 7.232 MHz (phone). And the FOXHUNTER'S will coordinate on the Colorado Repeater Association's repeater 147.225 MHz (+600kHz). This will also be used for some local information during the flight. Thanks in advance to the Colorado Repeater Association for the use of their repeater. REMARKS: Edge of Space Sciences will provide the platform for Cherry Creek High School and Thunder Ridge Middle School to study the lower atmosphere. Cherry Creek H.S. students have modified a geiger counter to meet the EOSS interface specifications which will measure the alpha, beta, and gamma levels of radiation vs. altitude. The experiment will gather data that should interest local NASA and NOAA officials. Thunder Ridge M.S. students will make graphs that will help them understand the temperature vs. altitude and balloon dynamics by graphing the ascent and descent rate of the balloon. The project will be presented at this years Denver, News 4 Education Exposition at the Colorado Convention Center on March 11,12,13 1994. More information about the EXPO can be obtained from EOSS.
