ITPASS
InstantTrack Satellite Pass Table Generator

Must Be Art > Software > ITPASS


Description

ITPASS is a companion program for InstantTrack. Using the satellite database and station location information already maintained by InstantTrack, ITPASS generates tables of satellite passes. For each time a satellite appears above the horizon, ITPASS generates an output line giving the starting time of the pass (AOS), the ending time of the pass (LOS), and the maximum elevation above the horizon achieved during the pass.

Users wishing to plan future amateur radio operation on the satellites can use the generated tables to determine when to be active and on which satellite. Users wishing to automate the operation of a satellite groundstation can use the program to schedule automatic operations.

ITPASS is a DOS command-line program that runs in text (TTY) mode.

System Requirements

To run ITPASS, any environment capable of running simple well-behaved text mode MS-DOS programs, including all versions of MS-DOS, Windows, OS/2, and many emulation environments.

To make sense, though, you also need to be able to run InstantTrack on the same machine. See the InstantTrack system requirements.
