Hi all, It fills us with astronomical joy to announce the release of orbit-predictor 1.9.0! 🛰 orbit-predictor is an open source (MIT) Python library maintained by Satellogic used to propagate orbits of Earth-orbiting objects (satellites, ISS, Santa Claus, etc) using TLEs (Two-Line Elements). orbit-predictor wraps the excellent python-sgp4 library by Brandon Rhodes, and provides a simple API to compute satellite passes over specific locations, find out their AOS and LOS (acquisition and loss of signal, respectively), and retrieve the satellite position in ECEF (Earth-Centered, Earth-Fixed) coordinates. Furthermore, this release adds new predictors based on classical orbital elements to facilitate orbit modeling. In particular, there are new functions to create planar constellations of Sun-synchronous satellites. orbit-predictor is cross-platform, works in Python >= 3.4 and can be installed using pip: pip install orbit-predictor Please check out our GitHub repository for further information and complete release notes. Bug reports are more than welcome! https://github.com/satellogic/orbit-predictor Per Python ad astra! -- *Juan Luis Cano Rodríguez*
