I was under the impression that GPS was heavily disabled/interfered in the area. Do these use a different guidance system to reach their targets?

- born2discover 2y agoI would assume Russian military would not be relying on GPS but use GLONAS[1] instead. [1]: https://en.wikipedia.org/wiki/GLONASS https://en.wikipedia.org/wiki/GLONASS

- seventytwo 2y agoRussia has its own constellation called GLONASS. It might be possible for Ukraine to jam that and GPS. I’m not sure how that would affect the bomb’s accuracy. I’m sure Ukraine is researching this.
- isubkhankulov 2y agoGPS is indeed jammed. Ordinance in such an environment often relies on interial navigation.
- 13of40 2y agoApparently they use a jamming-resistant GLONASS receiver module: https://mil.in.ua/en/articles/kometa-challenge-for-ukrainian-ew/ https://mil.in.ua/en/articles/kometa-challenge-for-ukrainian...
- LightHugger 2y agoGPS is almost never used for military guidance systems compared to inertial dead reckoning, GPS is too unreliable and easy to jam!
- sudosysgen 2y agoThat isn't true. Inertial guidance systems that work for appreciable flight times are too expensive. Many military systems do use GPS, such as HIMARS, Excalibur, JDAMs, etc... If I had to guess, the reason why the above are jammed and the UMPK isn't is because of better integration with the launch platform and a shorter flight time leading to less inertial drift over time, plus a very large warhead to make up for inaccuracy.
- denton-scratch 2y agoMost ATACMS use GPS: https://en.wikipedia.org/wiki/MGM-140_ATACMS#Variants https://en.wikipedia.org/wiki/MGM-140_ATACMS#Variants The UK's hot-shit guided artillery shell uses GPS: https://en.wikipedia.org/wiki/M982_Excalibur https://en.wikipedia.org/wiki/M982_Excalibur Yeah, GPS is seriously unreliable anywhere around the Baltic and Ukraine.
- dragonwriter 2y ago> GPS is almost never used for military guidance systems compared to inertial dead reckoning GPS is lighter, cheaper, and more accurate (when it works) than inertial navigation systems (which are more reliable to work at all) and is widely used alone or alongside inertial navigation on weapons systems.

- throwaway4good 2y agoI don’t know about their glide kits but the lancet drone has camera based guidance and uses a nvidia sbc.
