[@leod-sigefast]

FABs don't need to be accurate as they are area bombing basically. Saturating an area with bombs. The gliding ability is important to Russia as it gives them safe distancing to drop. The FAB "accuracy" isn't really important as Russia doesn't mind flattening everything in Ukraine and the payload is so big that 100m, 200m even 300m is "accurate" enough to destroy a building/strongpoint. Ukraine needs accuracy more so than Russia to target specific units. They don't won't to destroy their own country in the process.

The Russian-Ukraine war is not a good showcase of American made weapons, as such they’re not good showcases of western weapons over all which are to an extent designed with the American army in mind. IE the EU nation would be fighting a 3rd world country without the US and they won’t need the anti jamming capability. Or they’re fighting the Russians, which will mean the Americans are involved. As such American air power is heavily factored in, as well as their SEAD capabilities. These jammers would not survive long in the way they’re currently employed in that threat environment and we would more likely see sporadic jamming of focused areas of the front to cover big pushes. Don’t forget the 2 most potent air forces in the world both belong to the USA lol.

Well done, congratulations, you manage to communicate difficult concepts in a completely clear and simple way...!!! Greeting from Rome

[@ffsletmein4321]

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

[@nasosst3092]

This is the best prospective answer to the jamming problem. Otis could try to integrate the quotient of the vector matrix of the positions that we're over that of the positions we are not.

[@WEPayne]

Antennas have broad beams an modest gain. But even simple antennas have very sharp and deep nulls. The most effective countermeasure is to point a pattern null at the jammer.

[@Jordan-dt6qx]

The reason why INS based weapon systems include GPS is because relative to the INS, GPS receiver is quite small and cheap. It augments the INS system by providing up to date position information, allowing the INS to correct/reset the accumulated drift. For the weapon itself, outside of shielding/directional antennas, one of the best solutions to jamming is actually speed. Since INS drift is a function of time, the faster you go, the less time you spend within range of the jamming systems. When you get up to cruise missile speeds, 20-30 mile effective range of jammers, is small enough to where rather cheap and small(yet ITAR controlled) sensors can achieve a couple meter accuracy. The other solution to jamming is image recognition for terminal guidance. Using IR sensors and AI image recognition will allow target detection/tracking easily at hundreds of meters. That VASTLY decreases the required INS accuracy, while also allowing for the tracking of moving targets. INS accuracy could open up into the hundreds of meters! For the battlespace, the solution to jamming is relatively small long endurance UAV's with directional antennas, and some radio hardware. They'd work in sets of 3 or more to triangulate the jammers. Passing the targeting data to many various ground/air weapon systems. Think of it as a counter artillery for jamming. I wouldn't be surprised if In future war, the poor soldiers who get assigned to the units who deploy jamming equipment, will having some of the shortest life expectancies on the battlefield. I'd bet a good bit of money that whatever agency is operating the USA's ginormous SIGINT satellites, knows every single time, when a jammer is powered up.

[@tedarcher9120]

Radio recon satellites are a thing, you just need enough of them. Then you launch a gmlr or something at the jammer

[@zemm9003]

You are delusional

[@hanskrause8315]

I was surprised he didn't mention visual guidance. The Lancet has the hardware necessary to segment roads and rivers out of images and then use a particle filter and reference maps to infer its position. Sure, the accuracy isnt 3 meters but you can use computer vision to id targets once you get there. Regarding targetting the jammers, the solution could be to have teams of several jammers assigned to one area. If they constantly move and switch with each jammer on for less time than it takes for a harm missile to reach them you would have to carpet bomb the area to deal with it.

[@Jordan-dt6qx]

@@hanskrause8315 sure, they could be mobile. But then they’re much more expensive, and need to be manned. if you want to switch them, you’ll need 3-4 times as many as you’d otherwise need for a given area. So, your counter to the counter, is multiplying jamming costs by probably 10x. That’s not the right move. AI target recognition using IR sensors will easily target a moving vehicle. The time it takes a missile to travel the 20 mile effective range of jammers, is not much time. 90 seconds is not enough to use your jammer, pack it up, scoot to the next location, set everything back up, and then turn jammer back on. All of that is at least 10 minutes.

[@hanskrause8315]

@@Jordan-dt6qx We must be missing something. Otherwise it just seems too easy to destroy jammers. If you had 6 jammers (needing 30 seconds to raise their masts) jamming 30 seconds each moving at 30km/h between jamming sessions, each jammer would be 1km away from its last jamming session when it turned on. Fuel and logistics costs are for sure greater but if I were an ew soldier that's certainly what I'd want.

I'm a kind of guy who is more on the "cautious" side of personality. I really really love fool-proof and rugged things.

You can't jam a wire-guided AT missile, you can't jam the location of sun either. It seems to be that due to historical and geopolitical reasons, the Russian military tends to think a design thing in my way rather than the "cool" way.

Definitely not true. GPS is relatively easy to secure against jamming (directional antennas -- listen up not down -- and ofc there's aslo the simple brute force approach -- add more satellites/increase power output). Technically it's even easier to secure against spoofing. So far there's no identification mechanisms whatsoever in GPS tech -- there's been no need for this. Hence, the current problems with spoofing. People are lazy, they usually don't do things if they can get away with it.

I don't understand the problem with inertial guidance. You said it's good for short ranges, and that's all its needed for, since the range of GPS jamming is relatively short, as you pointed out. So why not just use GPS for initial guidance and an inertial system (which can be updated from the GPS during the pre-terminal flight phase) for the terminal guidance?

One solution I have considered lately is AI driven navigation. One with the ability to keep track of changes of direction and terrain recognition. The fire control technician would provide the drone with a three dimensional map to the target with accurate terrain and structure information of the possible routes. It could use the stars to help navigation but would not be necessary. Once released no amount of signal jamming or spoofing can deter it from accurate weapon delivery.

Infrared imaging with target recognition at final aproach makes the GPS jamming ineffective. Most Israeli air to ground weapon (eg. SPICE bombs) uses it, but GBU-53/B StormBreaker also has this feature. Terrain-contour-matching (TERCOM) is also a reliable method for weapon navigation, which existed well before the GPS-era. Tomahawk and other CM still use it.

[@seekrengr751]

Correct - I worked on the engineering team for the Stormbreaker Seeker way back in 2010. The Seeker is actually tri-mode, with MMW radar, uncooled imaging IR (UCIR), and Semi-Active Laser (SAL) designation options. This makes it an all-weather munition. The Wikipedia entry is fairly accurate without a lot of detail. Suffice it to say that the INS part of the GPS/INS can very reliably guide the glide bomb to within a square mile or so of the target zone where the Seeker takes over. No GNSS required. en.wikipedia.org/wiki/GBU-53/B_StormBreaker

[@84rb]

@@seekrengr751 Why do you need MM radar an IIR at the same time? It makes the munition expansive, while only one of the would be enough to find the target. I prefer SPICE-250 - much cheaper and to the job just as well!

[@seekrengr751]

@@84rb While IIR has higher resolution than MMW radar, MMW penetrates rain, fog, and clouds much better than IR so makes terminal guidance all-weather. MMW is also active, which has advantages and disadvantages. The main disadvantage of course is that it can be detected (and maybe jammed by a broadband jammer) by a potential target, which is why the frequency is classified. The advantage is that it does not require thermal contrast to recognize and track a target (the autonomous target algorithms handle moving targets well). Targets that are not operating (generating heat) can often have very low thermal signatures (as when wet) or may be camouflaged with shrubbery. MMW radar sees through most camo well, better than IIR, and can acquire and track a wet target. The SAL sensor provides a CEP much smaller than that of SPICE-250, and so does the sensor-fused IIR/MMW when both are employed. That makes Stormbreaker a more precision weapon besides the all-weather capability.

In addition to terminal homing seekers available for JDAM and SDB-I guided bombs there are of course HOJ (Home On Jamming) seekers which onto and target the GPS jammers destroying them.

You don't want to shoot a "dumb" home on jam over the heads of friends. In the case of the glsdb, it may end up being as simple as a timer. There are no friends past position x, so after x, then on home on jam.

Given time to adjust to these tactics the west will develop such systems, that is if they truly are that useful. The jamming-EW field is a russian specialty, no other western adversary seems to prioritize it so it might be too limited of a use case for the US to invest seriously in this sense.

Dear Millenium7, I'm not writing to disagree with you regarding internal guidance. I just want to point out that even JDAM incorporates inertial guidance. This is actually what my business is working on. The problem with inertial guidance is not inherent drift. This is easy to compensate with calculation. The problems are cost, size, and complexity, in that order. Laser-mirror based gyros can be made very small and so can the computers and batteries but at a rapidly escalating cost. Multifaceted systems are coming, with basically inertial guidance on a chip, just not today.

An interesting topic. As a non-expert, It seems weird to me that that the solutions presented tend towards high complexity in order to solve the problem type of approach. The problem as I understand it, from a weapon system accuracy point of view, is that the electronic signals from the GNSS and used by the guidance system becomes less reliable near an electronically protected area and inertially bases systems loose accuracy over time and distance for a variety of reasons. Why wouldn't we be able to use the two systems independence to our benefit? The GPS guidance can be used to update/correct the inertial guidance system up to the point that the GPS data reliability looses fidelity. Close to the target, the inertial system in combination with a course projection calculation could help filter out or eliminate GPS position updates/results that could not be within reasonable probability from the projected course. Alternatively on complete loss or loss of confidence in the GPS guidance, the inertial guidance could take over and be reasonably accurate since it only needs to maintain a given course for the last few seconds over a relatively short distance. This certainly wouldn't 'fix' the problem, but it could be done with some coding and existing equipment in the guidance system. If it reduces the CEP to the blast radius of the weapon it would at least be an improvement to missing by 10s or 100s of meters. Perhaps this has already been considered but it's just a thought.

You exaggerate the rate at which russian jamming has been effective. Glide bombs, including JDAMS, have been used successfully in various theaters as of a few days ago. In order to jam, it takes a lot of power. It's not something that is man portable. You need a large generator, 10s of thousands of watts, and it's not practical to jam across the entire frequency spectrum. You did state that jamming is highly local, and so where some areas may have strong coverage, most have nothing. Especially on the front line. You also downplay the ability to use multiple antennae to be able to discriminate between multiple sources of a given frequency. Especially for cases where both the transmitter (satellite) and the receiver are moving, and the jammer is not. You'll wind up with the jamming signal falling in and out of phase with the satellite signal, which will make it possible to distinguish between the two from the receiver. JDAMS can optionally be fitted with CRPA antennas, which are actually hard to jam. We have publicly released datasheets claiming 90 dB J/S for artillery shell-sized receivers and over 120+ dB for bomb/missile-sized receivers (locked on in both cases). It's nearly impossible to break the lock at anything more than a few km, and that's with a powerful and expensive jammer. And the one aspect you glazed over was the effectiveness of HARM missiles against GPS jamming, which is one of the signals that modern HARM missiles have been programmed to seek. I don't know if that functionality has been available to Ukraine pilots given the limited nature of their soviet-block interfaces. For example, they reportedly don't have the ability to program a route for the HARM missiles. Acquisition of the F16s will solve this problem if it exists. But given that jamming requires large generators and antenna, these are resources that the Russians will not want to lose. And if Ukraine embarks on a shaping campaign against jamming, this will make the Russians think twice about turning these things on. Or, it will force them to keep jammers away from other critical resources, and thus provide diminished coverage. Either way, jamming is a highly risky strategy in a wild-weasel environment. And that's precisely the game that the F16 will bring.

[@piotrd.4850]

Dude. Ukrainian's won't be able to exectue one of most complex air combat scenarios after year and bit of 'training' (not to mention, their attitude to training received).

[@Oleg111222333]

What amazing amount of nonsense did I just read? A satellite receiving energy from relatively small solar panels has a weaker signal in advance than a ground-based source of interference powered by a cheap gasoline generator... Moreover, the source of interference is many times closer to the signal receiver... The closer the source, the less energy you receive needed to receive a signal. The F-16 will never get close to the front line, it will be used to launch missiles from long range, since the Russians are the leader in air defense. And the Russians produce air defense in large quantities. Already now, the Western media are morally preparing their population for the fact that the F-16 will not be a superweapon that will change anything and some of them will be lost...

I can easily see this being the case for longer range JDAM-ER which as wings and can be prone to air fluctuations. Basic JDAM is just guided tail kit and can be dropped and targetted as regular bomb, which can be done relatively well anyway and guidance kit will just correcting.
