uri_ba Posted May 11, 2021 Posted May 11, 2021 Hi all, I'm trying to find the angular resolution (accuracy/error not sure how you have it implemented) simulated for the Pod in the Viggen. I Know it's a very specific piece of information but that is what I'm looking for DOes anyone knows where I can find it? thanks! uri 2 Creator of Hound ELINT script My pit building blog Few DIY projects on Github: DIY Cougar throttle Standalone USB controller | DIY FCC3 Standalone USB Controller
Machalot Posted May 11, 2021 Posted May 11, 2021 Are you working on a tool to map the results with uncertainty included? 1 "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."

And as the Viggen is the only module that actually inclue this capability, not including it with the correct number would be a shame 1 Creator of Hound ELINT script My pit building blog Few DIY projects on Github: DIY Cougar throttle Standalone USB controller | DIY FCC3 Standalone USB Controller
Machalot Posted May 12, 2021 Posted May 12, 2021 Cool, so like a covariance analysis? "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."
TLTeo Posted May 12, 2021 Posted May 12, 2021 I guess to first approximation you can assume the antenna is diffraction limited, take some sensible guess (15 cm?) for the antenna size, and work from there?
uri_ba Posted May 12, 2021 Author Posted May 12, 2021 (edited) You overrate my math nothing that fancy. If i end up needing to guess, i'll guess based on gameplay. I prefer to get the correct numbers from the folks that actually wrote them. It's a computer program after all. The position of platform and emitter are known and accurate and it's up to the person that wrote the code go generate the noise and error margins.

Machalot Posted May 12, 2021 Posted May 12, 2021 Maybe it's in the lua files somewhere? "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot."

My rough estimate of that from my Viggen scale model would be ~20cm 1 1
Bananabrai Posted June 11, 2021 Posted June 11, 2021 I thought there was already another topic about this. I don't know the U22/A but in my eyes it should be better. Other systems of that kind from the same age perform a lot better. Unfortunatly that is not something to prove here and I don't know if the Viggens system is used in some variation on the Gripen or some other platform as their Global ELINT platform.
