DCS: F-16C Viper | Navigation Updating with FIX Taking

[@choasisgoated]

The first community I can say I’m proud to be apart of

[@itzanselmo1394]

Thank you Matt for bringing another DCS tutorial on the f16. I have now close to 150 hours on this module and I am loving it plus I learnt a lot from your videos.

[@bigblackahuna7815]

Hey Wags, this is totally unrelated to the video, but why are we not able to carry more than one BDU-50 or training GBU-12? I'm a weapons loader, and that configuration is loaded all the time. Thanks.

[@MrChaosProf]

Call me stupid but I don't get why we have to do this. Shouldn't the GPS keep the INS automatically aligned? Or is this just in case the mission timeframe / nation does not allow the use of GPS? Or do you have to do this when you pulled max G and then want to super precisely CCRP in the next second?

[@ImperatorTheodosius]

There might be a blended ins/gps solution, but the gps won't update the ins on its own. That's the pilot's job.

[@geshabuL_]

Over time, the alignment quality degrades so it has to be corrected. It only happens on long flights, so if you fly 50-150 miles I believe you should be fine.

[@rakedos9057]

I guess that's when GPS is not available.

[@ImperatorTheodosius]

@@agostonbazmajer1100 Reddit moment. That's how inertial navigation systems work. But what do I know, I only have over 3100 hours of military flight time.

[@williamwinborne3253]

@@ImperatorTheodosius So what is the point of In-flight alignment if the GPS cannot fix the INS?

[@wraith444]

What timing, I was just wondering when this would be implemented the other day. Nice!

[@Stubbies2003]

So Wags you are talking about this a bit backwards. You are talking about it "as if the steerpoint position has drifted off". The steerpoint isn't what is drifting but the current position of where the INS thinks it is at. Your HUD steerpoint diamond display is shown based off of where the aircraft thinks it is at and where the steerpoint is in lat/long/alt. So seeing the diamond not where you know the target or steerpoint is at isn't the steerpoint drifting but current position drifting.

[@ratsac]

A very subtle but important point made at 3:50 where you can see *ALL* the steer points move when you update one. So you can’t just change the position of one to, say use it for CAS, and then fly off to your other steer points and expect them to be in the same place.

[@robertschubert4809]

Is there any way you can just change one steer point with out the others being moved?

[@ratsac]

@@robertschubert4809 you would have to edit that steerpoint. Can’t remember how to do that right now. Been a while since I fired up the Viper.

[@delayed_control]

Makes me wonder, is GPS jamming coming to DCS?

[@airbornestuff]

That would make INS fixing even more interesting and important

[@alcmann]

Thanks @matt for the Upload ! are we going to be able to update based on OA1/OA2 offsets also ? Worked with a legacy viper guy this week and he had indicated they used wp offets with the radar to update as well off of known objects with high reflectivity. Thanks

[@TomerTalmor]

Thank you! Can't wait! So will A-CAL also come with it in the same update? :D

[@6la6ng6e]

What's the reason the color of the terrain changes @ 1:47 in the video?

[@CallsignJoNay]

Cloud shadows suddenly popping into existence.

[@2xKTfc]

How much drift would be expected over, say, six hours? A mile seems a little large already given the GPS correction. If the jet showed a delta of 7 nautical miles I'd suspect that the crew chief has a long night ahead.

[@orleansjunky4074]

what are the chances of getting in game training missions added for all the updates in the last year and a half

[@shagrat47]

Nice... Just popped up on my list.

[@asciiCAT]

how does having the ins in ifa(using gps) or a similar mode effect the need for this?

[@destroystheovik]

While a FIX only updates the current location your INS thinks you're at and does this instantaneously, an in flight alignment will realign your entire INS. In flight alignments also have quite a low accuracy and they usually require you to fly in a fairly straight line for several minutes.

[@Slug24]

Is this really needed in the block 50's with GPS?

[@shagrat47]

If it gets damaged or has a failure? Sure.

[@brunofagulha]

"INU's drift over time regardless of the wayoint type. This is for updating the INU's position."

Does it change steerpoint cordinates or does it change entire navigation system to match steerpoint?

[@heefie8659]

Great stuff. Is there a way in ME to start a plane in the air with degraded INS?

[@destroystheovik]

No, but if you make a mission that takes place before 1994 in the ME there will be no GPS available meaning that the INS will drift much more than it would with regular GPS updates.

[@Raven-sv4es]

Will there be an update to the Hornet as well or isn't it required because it uses IFA?

[@kenhelmers2603]

Cool FIX :)

[@VET0264]

Ty, I've been learning so much watching dcs vids, grim reapers and growling sidewinders are also great informational tools too!

[@karankakkar3999]

@@taerdryn they just announced it!

[@brandonchappell1535]

does this mean INS/wp will degrade over time (or does it already), absolutely requiring this? or is it, "there if you want it"?

[@hphp31416]

I think GPS is correcting INS all the time so not required with aviable GPS

[@hawaiianbiceps9784]

It’d be handy to fix the accuracy of a single steer points except it moves all your other steer points

[@Tattlebot]

This isn't recalibrating the steerpoint. It's to edit the aeroplane's position in the hope of reducing error.

[@jdliefting8926]

All new features are nice but talking about balance, when will there be a DTC function in servers and ME to take some workload off? Theres a lot of data thats clunky to input during missions that normally come from the cartridge which will save you a lot of tedious work so you can enjoy stuff like this more.

[@jdliefting8926]

@@wraith444 thanks yes i already use the DTC mod but who knows for how long they will support it. Hence my efforts to get this implemented into the sim 😁

[@wraith444]

​@@jdliefting8926 Understandable. I'm hoping they get it added soon, but at the same time if they're doing improvements to the core experience I have a feeling there are some other very big ticket items that will take precedence like AI improvements, fleshed out ATC, and so on... Things that really *need* to be in place before the official dynamic campaign can be implemented.

[@jdliefting8926]

@@wraith444 definitely! AI, dynamic campaign options, ME functionality etc. stuff like that would improve the experience a lot as well. I agree that a DTC is not a priority on that list.

[@Seragon4G]

Hi all! Is it possible to change the altitude on the steerpoint? Alot of multiplayer missions has steerpoints high above target area, and I would like to drop it down to the ground. Thx in advance!

[@MattWagner]

Use either the STPT or DEST pages.

[@OliverMiles98]

You can - press STPT/4 on the ICP, select the steerpoint you want and adjust the altitude.

[@ernestwinslow7316]

You can change/edit the steerpoint elevation in the steerpoint page.

[@Sinni64]

Do we have to do this in every scenario, or is this only necesarry when my GPS is damaged, or the timeframe of the mission doesn´t have GPS?

[@MattWagner]

As mentioned in the video, only after a rather long flight in which INS errors can accumulate.

[@Sinni64]

​@@MattWagner ah okay. I thought that INS drift gets fixed automaticaly by GPS in modern jets.

[@MattWagner]

@@Sinni64 Not entirely. Based on multiple references, updating can still be required.

[@MattWagner]

@@audunskilbrei8279 You will need to speak with Lockheed Martin about correcting their manuals then. As I said earlier though, A-CAL allows blending of GPS and INS. Also note that this is a pre-EGI aircraft.

[@dannyd7714]

Soo if I'm watching this correctly, I can move a steerpoint that's near a target, to on top of a target to make it easier for the Tpod to find the target?

[@TheCol111]

No. You're better off using mark points for that. This is simply for updating and re-aligning the INS in case it drifts too much. In fact if you tried to use this method to try and place a steerpoint directly on (a) target, all your systems would be too inaccurate to get any precise bomb drops off and whatnot.

[@OperatorPuski]

you could potentially do that but you also have Mark points to help you snap the targeting pod to specific targets.

[@OddElephantLTU]

DCS has navigation drift? Wow

[@MattWagner]

The Viper does

[@SPATZ33]

whats happening at 1:47 when the environment gets darker? ...is this a Bug? ... same thing happens at 3:12 ...

[@DAZnBLAST]

Yeah I saw that. It was when Wags hit right on the dobber switch. Landscape darkened?

[@BrotherBloat]

I initially thought it was a cut, but the head movement is flawless. I think what we're seeing is the time of day lighting changing in active pause, accidentally on the beat of the switches being pressed. On the second occasion, the dobber isn't yet pressed when the lighting changed

[@lukew2031]

It's kind of 'normal' in DCS at certain time and sun position.

[@solarwind9431]

Matt ! there is a problem using GBU-10/12!! bombs in CCRP mode refuse to be released! If changes have been made, then make a new guide, if this is a BUG, report that this is a bug and you know about this problem! I wouldn’t write those here and would write on the forum or in support, but I just ran into an inadequate reaction from the worker’s ED, they started waving a banhammer instead of giving an answer! I find this behavior unacceptable!!
