What was the duration of the launch window this day? According to Spacelaunchnow, the daily launch window was instantaneous, but there were daily opportunities from July 15 to August 12. Did it first enter a short period of LEO for phasing and/or staging, or did it launch directly into its interplanetary trajectory? From the timeline, it appears that it ...

This plot shows the pitch profile for a Saturn V from launch to Earth Parking Orbit and it's described like this: The vehicle rises nearly vertically from the pad, for approximately 450 feet, to clear the tower. During this period, a yaw maneuver is executed to provide tower clearance in the event of adverse wind conditions, deviation from nominal flight ...

However, it is not so based on the above preliminaries, what might be the cause for this? The linked paper does give a reason: "These specialized options are required to simulate certain physical constraints that are not modeled in the equations of motion." The physical constraint in the case of a vertical launch is very simple: The launch vehicle ...

I would say it is a good reference. It is not a book, but rather a 33 page paper (one page is distribution page so no real information). I got a copy of the pdf from dtic.mil. A quick search shows the url is https://apps.dtic.mil/dtic/tr/fulltext/u2/a069296.pdf but dtic is down right now. Semanticscholar.org reproduces the figure and gives the url above, ...

Earth Satellites: get TLEs from Celestrak or Space-Track and propagate them with SGP4. One way to do that and to also calculate their ground tracks (latitude and longitude) is the Python package Skyfield but there may be others. However I'm not aware of proper databases that you can download constantly updated positions already calculated each second. Things ...
