ADF/VOR radio for moving ships?

[Hammer1-1]

I am trying to get a moving ship the ability to allow the UH-1H to navigate to a moving ship. Problem is that the ship only has TACAN navigation, but the Huey only uses VOR/ADF navcom, and on the LHS class you cant place any static objects on deck without it drifting off the ship. Is there a way to add navigation assistance in the FM/AM radio range?

[shagrat]

Not at the moment. I need to check with statics. You should be able to place static planes, helos and personnel on the deck and lock it to the Tarawa. What I didn't try to place a radio message on a static via Trigger editor/script...

[Bailey]

UHF ADF does not seem to work in the Huey. Nor does TACAN VOR freq pairs. Just ruling some stuff out.

[Bailey]

Oh, if you contact the ship on VHF/UHF and and ask for Navigation Assistance, they will give you a bearing.

[randomTOTEN]

Yeah calling the ship and asking for a bearing is probably the best way to go. I have the same problem finding the Kuznetsov in the Mi-8 after an off shore SAR.

[Bailey]

Holly Molly. I found a solution. Please wait while I document it.

[Bailey]

Here is the jist of my solution. Have a unit broadcast on a khz freq. Due to the "units sink though the deck" problem, I chose an aircraft that could operate off of the LHD.

 

1.2Mhz is 1200khz. You can change the freq to what you want. Also, if you just want navigation instead of Congratulations by Post Malone, you can loop a silent sound file.

 

The AI will start up, do a circuit, land, shut off the chopper, but will keep transmitting the freq. There are ways to have the AI actually do stuff that may or may not be more believable, but that's a lesson for another time. I have been fast forwarding for a game-time of 1.5 hrs, so I'd believe that it works over a multi hour mission.

 

 

Ignore the trigger zone in the pic. That was for a failed earlier test.

 

[Hammer1-1]

Awesome! Ill give it a shot and see where this goes. Thanks for the assist, I will report back and give details.

Good Work Around!

ADF for ships is still not possible?

I think this could be a quick add on for an update.

I implemented this function without the need to include any additional units with MOOSE Framework.
1. Generate a Morse code like TKR at https://morsecode.world/international/translator.html
  Pitch: 400
  Character speed: 10
  Farnsworth speed: 10
2. Edit the audio file to include pause by extending its duration to 10 seconds
3. In ME create a trigger SOUND TO COUNTRY (Ukraine, morse.wav)
4. Name the LHA "USS Tarawa" in the ME
5. Follow the standard procedure for MOOSE to execute the following code:

carrier_unit = UNIT:FindByName( 'USS Tarawa' )

-- Carrier NDB
local CarrierBeacon = carrier_unit:GetBeacon()
local frequency = 0.42  -- in MHz
local modulation = radio.modulation.AM
local power = 100 -- Standard for VOR
local file = 'morse.wav'  -- Dots and Dashes: - -.- .-.
CarrierBeacon:RadioBeacon( file, frequency, modulation, power )

Nice! Thx given!

Many thanks for your detailled instructions, but homing to the beacon leads exactly to the initial point of my moving Tarawa instead to its current position. For testing purposes I've added a static Arleigh Burke right next to the movin' Tarawa and the origin of the beacon signal stays unchanged near the Arleigh Burke.

Mission: CA UH-1H MovingFMHomingMOOSE.miz

Track: CA UH-1H MovingFMHomingMOOSE3.trk

Did I miss something in the script or in the mission setup, is there another issue or is this type of beacon for non-moving units only?

I've downloaded the latest version of MOOSE from github.com and updated the mission, but the problem persists.

Is there any possibility to link the beacon to the moving Tarawa?

[Chump]

MOOSE uses trigger.action.radioTransmission() under the hood, which accepts a vec3 point of origin. This point does not move once created. The transmission will always emanate from that singular point in the map.

[AstonMartinDBS]

Thanks for clarification @Chump.

I'm just asking, why ED doesn't add the commands 'Transmit Message' and 'Set Frequency' to the advanced waypoint actions of ships? This it is already possible for ground units and makes it very easy to setup a well working beacon for such units, even if they are moving.

[cfrag]

I did not realize that this was still an issue (ME's progress sometimes appears glacial). If so, DML can resolve this easily with an "NDB" zone attribute and the zone itself linked to a unit. See the "ADF and NDB fun" demo that is included with DML. And yes, the transmitter moves with the ship. 

 

[cfrag]

And here's the demo itself. Click on the trigger zones and loot at the attributes. A trigger zone with an "NDB" attribute is an NDB that is managed by DML. There are two moving NDB in the demo, one following a Hummer on the airfield, the second attached to a battle cruiser, steaming north off the Batumi coast. Take the Huey, set its ADF to 540 kHz, and try to find it (the cruiser) in the rain.

Thanks a lot, @cfrag!

Your solution works great, and the mission file stays tiny compared to MOOSE!
