Announcement of EOSS-16

The flight of EOSS 16 has been delayed until May 1, 1994.

Due to technical difficulties with the Ozone detection experiment being conducted by Ranum High School, one week is needed to work out the problems.

All payload frequencies will remain the same.

Here is the updated fact sheet.

LAUNCH DATE : May 1, 1994
LAUNCH SITE: Thunder Ridge Middle School
                           Picadilly and Smokey Hill Rd.
                           Aurora, Colorado, USA

                                                       104.73544 deg West

LAUNCH TIME :  9:00 a.m.
FLIGHT EXPERIMENT: Ozone detection at various levels of the atmosphere
EXPERIMENT CONDUCTED BY: Ranum High School, Longmont Colorado.
PROJECT INTEGRATOR: Andy Kellett/ N0SIS
SECONDARY EXPERIMENT:  Testing of the APRS. (Automatic Position Reporting System)

FREQUENCIES:
Shuttle I:

  • Telemetry      144.340 MHz
  • Beacon         147.555
  • ATV            426.250

HF Net:

  • 7230khz Phone + or - QRM

Foxhunters:

  • CRA Repeaters  147.225 MHz

PURPOSE OF THE FLIGHT:

There are several experiments that are going to be run on the flight of EOSS 16.

  1. The primary experiment will be the detection of Ozone at various altitudes above Colorado. This experiment will be conducted by Random High School. The students are interested in the Ozone concentration and may do a follow up flight to see if the levels have changed. They will be graphing the results and presenting them to the school science fair.
  2. The second experiment will be the use of APRS (Automatic Position Reporting System). The controller will be sending down text strings that will include latitude and longitude in them which should plot the position of the payload on any APRS equipped packet station within the footprint of the balloon as the payload travels the skies of Colorado. The typical footprint extends to ALL neighboring states. So, if you are in southern Wyoming, south western Nebraska, western Kansas, western Oklahoma, northern Texas, parts of New Mexico and Arizona and Eastern Utah, look into tracking the progress of EOSS-16 with APRS. Of interest, noting the difference between Loran-C, which is used on Shuttle I, and GPS, which is used on Shuttle II.

In the Denver Metro Area check on my BBS, N0VSA-1 and find out where to get the APRS program.

------------------------------

From the APRS documentation:

THE LATEST APRS is posted on 410-280-2503 BBS.  After version 3.11 I will also always post a file similar to: 400to401.zip which will contain only the files that changed in the latest release.

------------------------------

Anyone interested is welcome to come to the launch site and experience what a EOSS flight is like. We will have the ground station computer set up and also have TV monitors set up so you can see the flight from the perspective of the payload's onboard B&W tv camera. After the payload has been launched there will plenty of people around to answer any questions that you may have.

Hope to see you there!!
