LARNACA ILS GP range seems too small.

[Hornet81]

Larnaca airport GP is not detected when established on the LOC at any distance.
The GP is detected when overflying the runway. Seems that the GP range is way small.

It's possible that the ILS was in the opposite direction. Localizer will be usable from both directions (with back signal reverse sensing).

Modern ILS systems do not have a usable back course signal, and back course approaches are not approved for operational use in many parts of the world, including the EU. The log-periodic antennas used by all major ILS manufacturers on the international market are highly directional, and have a front-to-back ratio of around 14dB. No usable signal radiates from the back of the antenna array.

DCS simulates years from 1900 to 2100. I believe that all localizers in DCS currently have back signals.

Feel free to believe whatever you like, but in this case you're wrong.

I flew over Kobuleti airbase and got front course and back course guidance. If that Syria airbase is different I don't know.

I stand partially corrected. There seems to be intermittent coverage behind the localizer array at LCA. This shouldn't be the case. Back course approaches aren't a thing in this area of operations.

 

The error reported by the OP is unrelated to this. The entry for the GP in the beacons.lua is rotated 88,955947° clockwise with regard to the LOC, and the 3d model of the M-array GP mast is also rotated approximately 90° CW:

{
		display_name = _('');
		beaconId = 'airfield47_0';
		type = BEACON_TYPE_ILS_LOCALIZER;
		callsign = 'ILC';
		frequency = 110300000.000000;
		position = { -8990.810547, 7.217739, -210314.343750 };
		direction = 48.171958;
		positionGeo = { latitude = 34.860647, longitude = 33.608001 };
		sceneObjects = {'t:336825842'};
		chartOffsetX = 3620.000000;
	};

	{
		display_name = _('');
		beaconId = 'airfield47_2';
		type = BEACON_TYPE_ILS_GLIDESLOPE;
		callsign = 'ILC';
		frequency = 110300000.000000;
		position = { -6839.587402, 5.000005, -208096.250000 };
		direction = 137.127905;
		positionGeo = { latitude = 34.881032, longitude = 33.630902 };
		sceneObjects = {'t:750780863'};
	};
