The PC version runs in 32-bit mode on Win95 and Windows NT. This program is primarily a planetarium program but it can compute andĭisplay artificial Earth satellites using standard TLE satellite files. Predictions, orthographic views and ground tracks from two line or AMSAT The late David Ransom's program uses the SGP4 model to produce tabulated That it needs the Visual Basic VBRUN300.DLL Version 3.4 and earlier versions are also available at the author's web site. Able to manipulate element sets in the case of delayed Gregory generates a ground track graphic using two line or AMSATįormat elements. Uses AMSAT format keplerian elements.įree program for DOS (Y2K compliant) generates text based predictions Win3.1/Win95) and WinTrak Pro (for Win95/NT 4.0) are also described.Īlan Pickup produced a program that computes the decay and re-entry timeĪ simple text based prediction program authored by Robert Berger builtĪround the N3EMO code, available in the UNIX section below. The HomeĬontains information about the latest version of TrakSat and allows a Propagation models used are SGP4 and SDP4. Produces a graphical display of the ground track in various projectionsĪnd a plot of the pass against the local (star-filled) sky. Program TrakSat generates predictions from two line elements. Produces an observation report in any one of the Observers identify their reference stars in a simulated binocular or telescope field of view, enter the observed geometry, and the program automatically Reduces observations of satellites relative to the background stars, into their Ted Molczan's ObsReduce, is an MS Windows program for positional observers, that Subject to the availability of data, it can also estimate the predicted visual magnitude. IDSat also lists the direction of travel, angular velocity and estimated prediction accuracy. Ted Molczan's IDSat assists in the identification of observed satellites, by computing and tabulating close appulses of known satellites relative to the observed time and position. AĬomprehensive magnitudes file is packaged with it. It is textīased, reading the input parameters from a formatted file. To generate predictions which include an estimate of magnitude. Mike McCants' program uses two-line elements Types of elements, and extracting various information from elements. Purposes, such as managing files of elements, converting between different There are also many utilities for non-prediction What follows is a selection of softwareįor various platforms with a short description and a pointer to the package If you want to set about generating your own predictions for observing then
