InstantTrack is now free to download, use, and distribute. Until February 2019, InstantTrack was distributed by AMSAT organizations world-wide as a fund-raiser. 100% of proceeds from InstantTrack went to support the amateur radio satellite program.

InstantTrack 1.00 was written by Franklin Antonio, N6NKF, with some components contributed by Paul Williamson, KB5MU. InstantTrack 1.50 was created by KB5MU, based on a post-1.00 beta version created by N6NKF but never released. Both authors gratefully acknowledge the help of numerous volunteers who assisted with beta testing each release.
