The objective of the
Small Radio Telescope Program is to acquire and operate a small radio
telescope in support of a comprehensive educational and research
program. This program will be directed at increasing the
understanding of science and electrical engineering in the local
schools and universities of the greater Daytona Area.
History of Program
In early 2007 a grant
application was submitted by the Daytona IEEE Section to the IEEE Life
Member Committee (LMC) to provide funding for a Small Radio Telescope
(SRT) Program. The purpose of the SRT Program was to acquire,
assemble and calibrate a small radio telescope to be used for teaching
radio astronomy, electronics, communications, antenna theory, and data
processing. The device will be used to support the teaching of these
technologies at the University Level, High School and Junior High
School Level, and provide workshops to home schooled students.
In January of 2008 we received confirmation that the grant
for
the SRT Project was approved by the IEEE LMC, and that funding had been
made available.

The Daytona Section received the funds from the Life Member Committee
on 21 January 2008. Once the funds were received we called the
kit suppliers and re-confirmed prices and ordering
procedures. The executive board met on Tuesday, February 12
to:
(1) Appoint Dr. Hugh Ward project leader, and appoint a support team to
work with him,
(2) Review the final purchase orders for the kit. The purchase
order for the SRT was mailed on February 16. Delivery is expected
in 8 months.
It was decided to mount the SRT on a Trailer for easy transport to
various audiences. The trailer requirements are being defined and
negotiations with a local trailer company for build is underway.
A Press release has been prepared and sent to the local press
concerning the grant.
While waiting for the SRT to be delivered, the Daytona Section
Subcommittee plans to focus on strategy and plans for making best use
of the telescope. For example, we will start to define what radio
astronomy experiments should be performed once the SRT is operational,
and define courses, lectures, projects, etc. that can be implemented
using the SRT as a focus (such as navigation, earth geography,
microwave antennas and receivers, quantum physics, radiation, physics
and many others).
The next meeting of the SRT team is scheduled for Thursday February 28,
2008.

The SRT Committee met at 6:00 PM in the Daytona Yacht Club to
review progress and status on the SRT. Hugh Ward reported
that the SRT has been ordered. He would like to name Diane
Sartori as assistant project manager to help with employing the
SRT, and working on the educational development side of the
program. Ms. Sartori is an astronomy teacher and has agreed to
participate in the SRT Program. Ms. Satori is currently
participating in the Goldstone Apple Valley Radio Telescope
(GAVRT) program and using it as a teaching tool.
Hugh Ward indicated that we might seriously consider participating in
this program at some time in the future. The GAVRT program
is a partnership involving NASA, the Jet Propulsion Laboratory (JPL),
and the Lewis Center for Educational Research (LCER) in Apple Valley,
California. The program provides an opportunity for students, teachers,
scientists and educators, by means of the internet, to control and
collect data from the Goldstone 34-meter radio telescope. Until
recently the Goldstone Radio Telescope was part of NASA's Deep Space
Network.
The group discussed some of the details associated with placing the SRT
on a trailer. Because of its physical size the antenna mount must
be capable of folding for transport and storage. Hugh Ward has
been in contact with both the SRT manufacture CASSI and MIT's Haystack
Hill facility concerning this problem. It was decided that the
storage configuration of the trailer and antenna system must be able to
fit into a standard one car garage with an overhead door, and should be
able to be set up and stowed by one person. The new CASSI antenna with
both azimuth and elevation motors requires a different trailer
design then the one available on the Haystack Hill website, or the
trailer design being produced by Stetson University for their SRT.
Charlie Husbands has taken on the responsibility of acquiring and
testing the software developed for the SRT. He will download the
simulator off of the Haystack Hill website and modify it to meet our
location and antenna design requirements. The simulator which
uses the same control console as the SRT will enable the group to
become comfortable with the control of the antenna and the presentation
of the collected data before the hardware is delivered.
The next meeting of the entire SRT team is scheduled for
Thursday March 27,
2008.

The SRT Committee met at 6:00 PM in the Daytona Yacht Club to
review progress and status on the SRT. Hugh Ward provided a
letter and purchase order for a cavity filter for the SRT under
construction. The cavity filter, designed to reduce out-of-band
interference, must be placed between
the antenna receiving element and the low noise amplifier. The
cavity filter requires modifications to the antenna's electronics
section so
it is necessary to acquire and install the filter prior to the
completion of the antenna construction phase of the SRT. At the meeting
the committee voted to acquire the filter and the
letter and purchase orders were signed and sent to CASSI.
A letter was received from Diane Satori
indicating that she would like
to make of presentation on the GAVRT workshop she recently attended.
Ms. Sartori is an astronomy teacher at Pine Hills High School in
Deltona, Florida. Ms. Satori is currently participating in the Goldstone
Apple Valley Radio Telescope
(GAVRT) program and using the Goldstone telescope as a teaching tool.
Her presentation will be made at Emery-Riddle Aeronautical
University, in Daytona Beach Florida, on April 9th at 5:00 PM.
At the present time Charlie Husbands is familiarizing himself with the
control software necessary to operate the SRT. This software
available from MIT's Haystack Hill Site provides a simulation
capability to permit the user to become familiar
with the operation of the SRT before the antenna and digital receiver
hardware is delivered. Charlie agreed to hold a short workshop in
May
2007 to familiarize the members of the Section with some of the
capabilities and limitations associated with the software developed for
the SRT system.
The SRT committee previously approved the placement of the SRT antenna
structure
on a trailer for transportability and storage. Hugh Ward has
agreed to assign Al Jusko of the SRT committee to work with the
trailer manufacture to develop and implement a mechanical design to
meet our transportation and storage requirements.
Hugh Ward indicated that he has a satellite dish and transceiver in
storage at the school which might be converted to provide a secondary
receiver for the SRT project. If the stored system is to be used
it must be removed from the school and relocated to another storage
location before 1 June 2008.
The next meeting of the entire SRT team is scheduled for
Thursday April 24th,
2008 at 6:00 PM.
