DCS Unrestricted SATNAV?

What would be Unrestricted SATNAV?

I'm confused here. Why would this be an actual issue? Is it that DCS somehow models GPS in some way beyond "the plane magically knows where it is"? Or is GPS jamming modeled? Or is glasnoss modeled in some way? Its just a confusing issue to me.

Unrestricted SATNAV allows NATO aircraft placed on REDFOR to still use the GPS in the hornet for example.

 

If you place a NATO hornet on REDFOR without this they can not use their GPS.

 

Also in the editor for mission making

 

 

Thank You! :thumbup:

first of all, it's probably only a first step towards a bigger picture, but secondly - and more importantly - i can see it already being an interesting feature for limiting a players ability on purpose.

the hornet should still have INS for navigation... maybe INS drift will get implemented soon... maybe SATNAV jamming gets implemented next...

Wouldn't GPS work in C/A mode without crypto keys set?

i would assume that accuracy could be heavily degraded, as c/a mode can probably be disabled or limited for a region. that's just an educated guess though...

I've always found it a weird decision on E.D.'s part.

 

- if RedFor country has sufficient home grown technology to maintain, arm and keep in the air an F/A-18, they're going to be able to make use of a GPS system.

 

If it's flying for Russia - presumably one of the FIRST changes they would make is to move it off relying on western GPS and onto their own GLASNOSS system - precisely to avoid what E.D. are modelling happening...

 

It might be that they end up with some differnet pages, or another screen on the dash, but in the interests of simplicity and removing the guesswork from what would be an obvious conversion - just leave the GPS system working for Red and Blue...

Yeah thats why im curious about it. Innthe context of DCS today it doesnt make sense. In the case of DCS tomorrow it would be coolz especially if ED developed a general NAV api for everyone to use.

GPS is actually modelled to some extent: if you create a mission in the editor with a date before 1994 or 1988 (don't remember exactly) GPS won't work because it wasn't used/existing IRL. Maybe, as some other users suggested, there maybe more coming in the future about GPS and INS in general.

P(Y) compatible receivers generally only use the C/A signal for time synchronization when acquiring the P(Y) PRN code.

Correct any mission with a date prior to 1986 disables GPS.

good to know. does it apply to all aircraft modules?

IDK,

I don't know what it was actually used for or if it applies to other aircraft in the game, but yes the data is there. For example there is data on satellite orbital information plus system type for 51 total satellites. I don't know what it applies to, honestly could just be the Ka-50 and is ignored for everything else. So yes there is data on GPS and GLONASS, the file defining all of this can be placed in a mission file and could foreseeably be used to modify or simulate the state of the network.

Yeah I agree with this point whole heatedly. Its not the best idea to tie certain functionality behind a coalition or dates used for a given scenario. Additionally the existence of that functionality is purely known from experience gained from running into that situation. It is problematic for starters because ED is assuming every single scenario will have Russia on Red and USA on Blue when they don't know for sure how someone will decide to setup a mission.

It's an interesting topic for sure.

 

 

Given the commercial importance of GPS, I doubt that the US would turn off the system, even locally, in any situation other than all-out total war. As opposed to the limited conflicts we have seen the past 75 years.

 

 

I suppose that, in these limited conflicts, Redfor can still use GPS...

Or they turn it off selectively over some area. Plus these days you have glossnass and gallileo.

I doubt that the US would turn off the system, even locally, in any situation other than all-out total war.

They do it today over the CONUS with some regularity. I don't know if that's a GPS based denial of coverage, or if it's a ground based interference signal, but it does happen and can cover entire states.

 

https://theaviationist.com/2019/02/08/basically-carrier-strike-group-4-is-jamming-gps-across-u-s-southeast-coast/

As an FAA NOTAM (Notice To Airmen), issued for airspace in eight of the FAA’s Air Route Traffic Control Centers, warns, GPS could be degraded from Caribbean and Florida north to Pennsylvania west to the eastern Louisiana, while the tests are conducted Feb. 6 – 10, at different hours.

 

...As happened in all the previous operations, we really don’t know which kind of system is being used to jam GPS. However, it must be an embarked system, considered that the source of the jamming is a location off the coast of Georgia, centered at 313339N0793740W or the CHS (Charleston AFB) VOR 173 degree radial at 83NM (Nautical Miles).

 

...AOPA estimates that more than 2,000 airports—home bases to more than 28,600 aircraft—are located within the area’s lowest airspace contour.

Still doesn't take away from the fact that the Russians have their own system, & that if they were flying F-18 / F-16 (s), that's what they'd be using.

 

Even the legacy Su-25s have a GLONASS system bolted on.

 

It's less realistic to give the REDFOR F-18 but deny them a GPS system than to just assume that if they had the aircraft, they'd make the GPS work off GLONASS.

If they are GPS capable they will already use GPS.

 

This feature was added for mission designers who want to use the US Aggressors in a redflg scenario as an enemy while still enabling their onboard GPS system. In the past any hornet placed on REDFOR would have lost that ability.

 

Also this allows MP server admins who place NATO hornets on either side to also use their GPS when previously they would not have been able to and only been able to manually align via TCN when on the REDFOR side.

…on that note, there really should be a way to disable GPS/GLONASS for the blue side.

 

Or, more symmetrically, have it enabled by default and offer a disable functionality for both sides so that there's not special treatment unless you really want it off for some odd reason.

That bracket looks like something you'd find on Thingyverse.com :megalol:

Does both the side and mission year play a role for the 430?
