RSBN/PRMG ground units usage guide

RSBN/PRMG ground units usage guide

We have prepared additional units for RSBN/PRMG navigation and landing systems. These will help you to set up RSBN/PRMG environment in any airfield. We have made it so these units can be placed freely anywhere on the map which will give some additional freedom for mission makers.

The set of this system consists of three individual components/units:

·         RSBN trailer/car (You can compare it with TACAN beacon)

·         PRMG Glidepath trailer/car (Glidepath signal for landing)

·         PRMG Localizer trailer/car (Localizer signal for landing)

You can find them in relevant countries in Mission Editor under Ground Unit > Unarmed category.

Let’s list nuances for each one of those components so you will get good understanding of how you can use them.

RSBN car

This unit is origin of RSBN signal. To activate RSBN on it you need to add Advanced waypoint action > Perform Command > Activate RSBN/PRMG beacon.

Channel field in this command corresponds to the channel aircraft equipped with compatible system will tune into. 40 channels available in total.

Callsign field corresponds to transmitted callsign over radio via Morse code.

This unit can be installed anywhere within airfield, bearing in mind it is an origin of RSBN signal for the vectoring aircraft.

 

PRMG Localizer car

This unit is origin of the PRMG localizer vector signal. Follow the rule of installing it 200 meters after the end of the runway to which landing is performed to.

Bear in mind that landing aircraft need to have clean line of sight to that unit to get the signal from it. If unit is placed on the slope and covered by the terrain hill for instance, landing aircraft won’t be able to get a good signal from it. PRMG units should be placed on the same elevation plane as the runway. Also, it is important to set unit heading to be aligned with runway landing heading. Additional symbology in mission editor is available when unit is highlighted, and we also added ability to fine tune heading with decimal numbers.

To activate PRMG signal on it you need to add Advanced waypoint action > Perform Command > Activate RSBN/PRMG beacon.

The general rule for the operators of these systems was to set channels as:

                RSBN channel + 2 = PRMG channel

 

PRMG glidepath car

This unit is origin of the PRMG glidepath vector signal. The rule of installing it is 300 meters after the runway start and on the side. This distance is important to adhere to in order to have correct landing vectors for glidepath. Distance on the side can be various and main practical point is to have this localizer car on the same altitude and plane as runway, otherwise landing glideslope will be inaccurate.

To activate PRMG signal on it you need to add Advanced waypoint action > Perform Command > Activate RSBN/PRMG beacon.

The general rule for the operators of these systems was to set channels as:

                RSBN channel + 2 = PRMG channel

Overall setup example

PRMG Glidepath and PRMG Localizer units operating for same location should be set to the same PRMG channel. Here is full setup example on the Beslan airfield

changed glideslope car to glidepath car to match ME

Very cool!

and now for ICLS and ILS

[joker62]

I've been waiting for something like this for a long time. Thank you so much.

[TGP14]

Thanks a ton ED for 3 absolutely phenomenal additions in this update (Mig-29/PRMG & RSBN Units/R-27 Updates), these are all obviously major steps forward for DCS!

If you guys still have the steam to cook-up a few more desperately needed units an ILS, TACAN, ICLS set of vehicles would be fantastic additions as well (especially for the Hornet/Tomcat which obviously can't use an ILS anyway)! Adding an FCLP Box with a land based IFOLS system would be the absolute cherry on top!

RSBN and PRMG is awesome, but will you guys add ARK? Its more important for Soviet helicopters.

Those new RSBN-PRMG vehicles are also compatible with the L-39 Albatros or the Mig-21?

If not, any plans to make it work?

L-39 should work as it uses our system, the MiG-21 as mentioned in the change log will need to be adjusted
(note: MiG-21bis from Magnitude3 is not compatible with this RSBN/PRMG system yet).

[Esac_mirmidon]

Thanks for the info, good to know the L-39 can use it.

[Beta Sokol]

[Beta Sokol]

Confirmed,

It works for the L-39 but you have to place 3 different units, you can't place them in a group.

So many thanks to ED, requested long time ago !

Question, what about the other FC planes like the Su-25, would be a nice addition ?

Thanks for this !

[Northstar98]

Thank you so much for this - it was sorely needed 

[gulredrel]

Thanks ED, great addition to DCS having now the equivalent to the portable TACAN unit. Also many thanks at @BIGNEWY for making this guide for correct placement of the new units.

Just downloaded the update and didn't have time to try out but I guess it's important to set the frequencies to different ones than the ones already being in the map? I remember having trouble with portable / shipborne TACAN frequencies which where interfering with corresponding DME channels on Syria map.

what planes are compatible with RSBN system? are all FC3 compatible with New RSBN/PRMG Airfield's in Cold War Germany Map and Caucasus Map? 

DCS: Caucasus Map by Eagle Dynamics

• Changes in RSBN and PRMG beacons of Krasnodar-Center, Krymsk, Maykop-Khanskaya and Mozdok airfields:
  • Removed frequencies of RSBN and PRMG beacons.
  • Tweaked channels of RSBN and PRMG beacons for better pilot experience 

 

DCS: Cold War Germany by Ugra Media

• Changes in RSBN and PRMG beacons of Gardelegen, Allstedt, AltesLager, Damgarten, Garz, Holzdorf, Kothen, Laage, Lerz, Mahlwinkel, Merseburg, Parchim, Peenemunde, Sperenberg, Templin, Werneuchen, Wittstock and Zerbst airfields

 

i tried these maps with the su-25 and the RSBN/PRMG do not work for these Airfields does the RSBN/PRMG work at all for FC3 aircraft

i tried on Caucasus Map but also couldn't get it to work?

Hi, no matter which map, era I cannot get these units to display on the list? Removed mods, no change. They dont appear under unarmed at all. Any ideas?

 

EDIT: When I open MIG29 "Final approach" quick mission in ME, I can see the cars and edit them. though they still not appear on the list. When one car is selected, only that type (of the three) is visible. trying to add new one to another airfield is not possible, they don't show up in the list.

Have you checked the clock symbol for historical mode being off?

Also check the country. It works for me with Russia, USSR or the combined forces red/blue. But will not work with GDR (even this should be possible, as they operated these equipment).

[tpisko]

That was it! Thank you.

Though why are these not available in historical missions? I tried years from 70s to 00s and it doesn't work in any.

[buur]

Hi guys, here a small script to determine the exact heading of the runways. Simply execute in a DO SCRPT trigger and change the airport name in the first line. Think could be helpful for the exact alignment.

myAirbase = Airbase.getByName("Pferdsfeld")
rny = myAirbase:getRunways()
name = myAirbase:getName()
if rny then
	for j = 1, #rny do
		local bearing = rny[j].course * -1
		
		degree = bearing*180/math.pi

		if degree < 0 then
			degree = 180+ degree 
		end
		
	antidegree = degree + 180
	
	if antidegree > 360 then
		antidegree = antidegree -360
	end
		
	
	rnyname = rny[j].Name	
	local text = string.format( '%s runway %s heading: %.2f ; anti heading: %.2f',name,rnyname,degree, antidegree)
	trigger.action.outText( text , 20 , false)

	end
end

I guess the corresponding data for this new units has not been populated yet. Many new units or modules do not fit with the historical mode on first release.
