SatPC32 is satellite prediction software developed by DK1TB that enables radio amateurs and satellite ground-station operators to forecast the precise passes of more than 25,000 orbiting transponders and beacons. Now in its single-version release 12.10, the program calculates azimuth, elevation, Doppler shift, path loss, and squint angle for every visible spacecraft, then generates real-time tracking displays, audible alarms, and automatic rotator or transceiver control so users can schedule and execute VHF, UHF, microwave, and S-band contacts without manual intervention. Typical use cases include planning portable field operations for amateur-radio satellites, synchronizing antenna arrays during educational demonstrations, logging telemetry from weather or CubeSat missions, and synchronizing uplink/downlink frequencies for linear or FM transponders. The application belongs to the science / radio-astronomy category, yet its rigorously updated orbital elements, support for the two-line element (TLE) format, and rig-control interface also make it valuable for university ground segments and emergency communication exercises. Users can filter the internal space-object database by launch year, operational status, mode, or uplink/downlink band, export pass lists to CSV for further analysis, and overlay ground tracks on world maps for visual mission planning. Because the underlying SGP4/SDP4 propagation model is refreshed automatically whenever new Keplerian data are published, SatPC32 12.10 maintains sub-degree accuracy for planning low-earth, elliptical, or geostationary passes weeks in advance. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
