About Smart Radio Telescope
Smart Radio Telescope is the mobile client for a self-built satellite-dish radio
telescope with a motorised Azimuth / Elevation / Polarization mount. It
connects over your local WiFi to the telescope's Raspberry Pi controller and
turns a phone into its control station.
SKY VIEW AND RADIO MAPS
* All-sky dome with stars, constellations and the dish's current pointing
* Radio sky overlays from the Haslam 408 MHz and HI4PI hydrogen-line surveys,
so you can see where the sky is bright at radio wavelengths
* Object catalogue with the Sun, the Moon and radio targets such as Cas A,
Cygnus X, W51, IC 443, M31 and 3C 273, each with a short description and
its rise and set times
* Tap a star or object to point the dish at it
RASTER SCANS
* Drag a rectangle on the sky to map it
* Choose the sweep axis, the pattern, the speed and the number of rows
* Watch the map fill in as a live heatmap while the dish sweeps
* Share the finished scan as an image
SOURCE TRACKING
* Eight bright radio sources ready to observe: Cas A, Cyg A, Tau A, Vir A,
Cen A, Sgr A*, Orion A and Fornax A
* Shows which of them rise high enough at your site
* One tap starts tracking; the mount follows the source across the sky
MOUNT CONTROL
* Big STOP button, homing of all axes or one at a time, wake and sleep
* Go to horizontal (Az/El/Pol) or equatorial (RA/Dec) coordinates, or track
What's new in 1.1
Radio sky overlays (Haslam 408 MHz, HI4PI) and an object catalogue with rise and set times. Raster scans with a live heatmap, shareable as an image. Tracking of eight bright radio sources, a virtual joystick, a live signal chart and Raspberry Pi health. The phone's position can set the site. Landscape layouts and many fixes.
