Included with every SPIDER radio telescope, our RadioUniversePRO software allows you to control the antenna position and acquisition parameters of the receiver. This way you cannot only record data coming from the sky (deleting eventual artificial signal interferences) but also transits or radio-images of radio sources in the sky you want to study.
RadioUniversePRO: key features
- Control software for SPIDER radio telescopes
- Intuitive and easy-to-use: in single a screen it shows all the controls of the radio telescope
- Mount control: it allows you to remotely control all WP-100 alt-az computerized mount and German computerized equatorial mounts equipped with an ASCOM driver (it requires the installation of ASCOM platform)
- Receiver control: it allows you to connect and control H142One receivers
- Data save in graphic format (PNG) and raw (FITS) compatible with NASA FITS Viewer.
RadioUniversePRO: IF Monitor
It displays the data coming from the radio telescope to the receiver in form of a Power Spectrum (upper row) and FFT Waterfall (lower row), both for Left and Right Polarization. Power spectrum is the graphical representation of the electromagnetic power distribution in the operative band, through the RF chain.
RadioUniversePRO: BBC Tool
BBC Tools window allow you to visualize in real time the uncalibrated power spectrum of the input signal in both IF left and right. RadioUniversePRO allows you to use a group of digital filters (16+16) fully tunable on the 2 Intermediate Frequencies. Every filter is identified by a BBC (Base Band Converter) label and a number from 01 to 16. Every filter can be set in frequency and bandpass.
RadioUniversePRO: Offset alignment
Offset alignments is the instrument that is used to synchronize the radio telescope on the radio sources position on the sky, by reducing the pointing errors on 2 axis of the mount. The radio telescope will perform automatic measurements of Total Power values by varying latitude and longitude offsets. When the procedure is completed, RadioUniversePRO will complete plotting of the graphs and calculate the best offsets to send to the mount electronics in order to better align to the pointed radio source.
RadioUniversePRO: Source visibilities
Source Visibilities tab lists the most powerful radio sources in the sky. This tab is designed in order to allow you to have a quick idea on the radio sources available that you can point and study with your radio telescope (detection level is different based on the SPIDER radio telescope model you use). In order to point the radio telescope to any of the listed radio sources, just make a mouse double click on the radio source row and the radio telescope will point it.
RadioUniversePRO: Gain calibration
Gain Calibration procedure executes Total Power measurements (by using the proper BBC filters the users selects) on a set of radio sources with a known radio flux by literature. During the Gain Calibration procedure, a proper polinome function allow RadioUniversePRO to calculate the theoretical flux in Jy the radio telescope would record without any atmospheric attenuation or any gain loss because of different factors (antenna deformation because of its weight for example). Note: this feature is actually under development and will be activated soon.
OnOff tab allows you to perform an ON-OFF recording on a radio source. The radio telescope is pointed to the radio source (ON position) and the data is collected. Then it’s moved in a position OFF the source and another set of data is collected and used to calibrate the previous one. This way you’re able to reduce the radio noise and the effect of external components (like the Earth atmosphere).
During acquisition, every spectrum is shown in the “Spectrometer” tab, both for left and right polarizations. At the end of acquisition, RadioUniversePRO will automatically perform an average of the data and will display the spectrum. During data acquisition, you can zoom in the spectrum to better visualize parts of it.
RadioUniversePRO: Total Power Plots
Total Power Plots are the perfect instruments to easily visualize and record the variation of the radio signal flux over time. Just select the “Plot” option and you will see the value in counts for every BBC filter plotted over time. In the Total Power Plots tab you have the controls that allow the radio telescope to automatically perform a Cross Scan.
Mapping tool lets you scan a sky area and convert it into an image map. Select the Mapping tab to reveal Mapping options in the Setup Map area. You can set Width/Height (the side of the Map you want to create), Delta (a moltiplicative factor of the HPBW of your radio telescope, this is the distance from pixel to pixel of the map RadioUniversePRO will create), Average(number of seconds the antenna has to track every pixel and average values).
RadioUniversePRO: Weather Control
Weather Control tab shows all the data related to environmental conditions and coming from the external sensors of the radio telescope. Here you can connect to the Ultrasonic Wind Sensor and monitor wind speed, check for internal temperature of the WP-100 and WP-400 mounts, and connect to the All Sky Cam and see in real time, inside of the RadioUniversePRO software, the radio telescope you’re controlling.
RadioUniversePRO: FITS format
RadioUniversePRO lets you save recorded data in graphical format (PNG) as visualized on the user interface but you can also save raw data in FITS format compatible with NASA FITS Viewer, the same software often used by professional radio telescopes. This way users can quickly open and view their data and export them to process with other softwares.
