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 an RA/Dec position * Travel-range hints and warnings before a target would hit an endstop * Step buttons with a configurable step size * Virtual joystick for driving azimuth and elevation by hand: the speed follows your finger, the dish stops the moment you let go, and a red rim shows when an axis has reached its travel limit LIVE TELEMETRY * Position, motion and homing state of each axis, pushed live from the mount * Endstop switch levels and the motor controller's temperature * Live radio signal chart with minimum and maximum * A clear banner when telemetry goes stale or the mount refuses a command SYSTEM * He
