3. Any celestial object in space revolves/displaces with
respect to earth. In order to measure its radio waves
emission it becomes a necessity to develop a portable
stand on which we can place the relevant RADAR or
Antennas or other instruments capable of not only
track the objects body but also measure appropriate
data. Our proposed idea is to develop a radio waves
detecting antenna, mount it on a 2-axis rotating
stand and observe the resultant radio waves via RTL-
SDR dongle. The entire setup is controlled by
Raspberry pi microcomputer. Due to R-Pis wireless
capabilities we can easily receive results via Wi-Fi or
Bluetooth and thus making entire antenna setup
mobile.

4. Software-defined radio (SDR) is
a radio communication system where components
that have been traditionally implemented in
hardware are instead implemented by means of
software on a personal computer or embedded
system.
Such a design produces a radio which can receive
and transmit widely different radio protocols
(sometimes referred to as waveforms) based solely
on the software used.

5. RTL-SDR is a dongle that can be used as a
computer
based radio scanner for receiving live
radio signals in your area (no internet
required). ... The RTL-SDR
is also sometimes referred
to as RTL2832U, DVB-TSDR,
DVB-T dongle, RTL dongle,
or the "cheap software defined radio".
Its frequency range is betwwen 50MHz to
1.7GHz.

8.  Currently working on design of antenna.
 Designing V shaped NOAA antenna.
 Its working frequency is about 137MHz.
 It uses 2 copper rods for V shape and a
connector.
 This antenna will be connected to SDR Dongle
to receive the required data.

9. Next step is to design the wooden stand of
antenna.
It will provide support
for antenna as well as
set the azimuth and
zenith angle for
antenna through
2 motors
and gear setups.

12.  Used as experimental model in universities
for learning radio astronomy.
 Can detect Sun position , which can be used
to detect various information.
 Can be used for research work.
