DRAMA_Bug

GitHub to Share a Code That Leads to a Quasi-Infite Loop Bug in DRAMA-OSCAR

Bug Source

So far as seen in the code with the original mission leads to an error that happens related to the start date of 2035/01/01 Then a second mission the start date connected to the bug shifted to the 2037, however, it can be expected as the second mission has a shorter total lifetime than the orginal.

Orginal Mission

Duration: 3 + 5 years
Inclination: 97.5
e = 0.000001
Cross Section:

  • Initial [3 years]: 0.0929 or 0.1813 m2
  • De-Orbit [5 years]: 0.205

New Mission

Duration: 1.5 + 5 years
Inclination: 97.5
e = 0.000001
Cross Section:

  • Initial [1.5 years]: 0.09 m2
  • De-Orbit [5 years]: 0.936 m2

Some Conclusions

THe change in when start date that leads to the bug is in line with the shortening of the mission. THerefore, it makes me believe that the error could be located in the the date range 2042 +- 1 year, howeverr, I still dont know what is the altitude/inclination/etc that is in combination with the date because there are other start dates in the original analyzes that go through 2042 without a problem. But I could be wrong about the problematic date range.
