NASA GMAT sample script providing deltaV above analytical result when aiming to GEO Height
I am using the GMAT example script available at \samples\Ex_GEOTransfer.script (R2022a) to compute de deltaV from LEO to GEO including change plane maneuver.
The problem is that the script seems to be ...

What is Earth's apparent magnitude from geosynchronous orbit?
How bright is a "full Earth" from geosynchronous altitude (22,200 mi) and would it be dangerous to look at a full Earth for too long from that distance without wearing a dimmed visor?

Geo satellite - antenna gain contours to heat map in STK
I am using STK to show antenna gain contours on the ground from a transmitter on a sensor on a geo bird that is tracking a receiver on the ground. With good resolution I can create great images that ...

A black cube 1 mile per side appears in geosynchronous orbit around the earth. Who would spot it and how would they do it? How easy would it be?
This is not intended to be a math question, so much as an understanding of how the current technology and techniques would view this problem.

What was the first spacecraft intentionally moved from GEO to the graveyard orbit to die? (just a bit above geosynchronous)
Why “super” for supersynchronous orbits? Why not “trans”? and discussions and answers there got me wondering:
Question: What was the first spacecraft intentionally moved from GEO or geosynchronous to ...

What are the benefits of supersynchronous transfer orbits?
Some satellites are injected into higher apogee than standard GTO apogee of 35 786 km. Next the satellite then has to increase its perigee ( usually 250 km ) to GEO altitude. Then the apogee has to be ...

Are there any satellites in geosynchronous orbits that are neither geostationary nor 'wobbly geostastionary' (figure of eight geostationary)?
None of the examples in this question: Are there any satellites in geosynchronous but not geostationary orbits? are nothing like geostationary. They still stay above the one side of the earth. What ...

Computing a new TLE following a delta-v impulse?
Is there some code or a library out there that can take orbital elements, add a known delta-v component and then compute a new TLE? I found this one https://apps.dtic.mil/dtic/tr/fulltext/u2/a289281....
