Thanks for the recommendations! We were trying not to use the numerical shadow analysis ones because the slow speed of the iterative calculations and it's easier to incorporate J2 into the function. The quartic function is supposed to just find the zeros of an equation if you input the...
The sun transit is incorrect. The orbital elements match perfectly with what I'm calculating but the function is supposed to spit out shadow entry and exit points. The function itself is referenced in the book and downloadable from the internet, but it has some bugs in it out the gate. For...
The issue is not knowing the orbit (if I'm understanding your explanation correctly). And I'm using Kepler to calculate the delta t but the problem is the input values for E are incorrect. I'm adding more specifics based on the question below you if a more detailed explanation is warranted.
Hello fellow Space People,
Currently trying to create a function in MATLAB to input an R and V vector and have it spit out all the orbital elements as well as shadow entry/exit locations. I have the Vallado "Fundamentals of Astrodynamics" book and I've used it religiously. I searched on here...
Hey guys, new member here. Currently a graduate student in Aerospace Engineering at Purdue. Hoping to be able to peruse the forums to enhance my knowledge and understand, maybe help some people out, maybe get some help haha.
