Hi.

You can create a custom map type with Projection.

The tutorial how to create

zhuk.cc/wiki/index.php/Zh_GoogleMap_CustomMapType

OK.
I post

function(coord, zoom) {
return "http://vec0"+((coord.x+coord.y)%5)+".maps.yandex.net/tiles?l=map&v=2.16.0&x=" +
coord.x + "&y=" + coord.y + "&z=" + zoom + "";
},

to Get Tile URL function.

Global scope:
var MERCATOR_RANGE = 256;
function degreesToRadians(deg) {
return deg * (Math.PI / 180);
}

function radiansToDegrees(rad) {
return rad / (Math.PI / 180);
}

Projection scope:

this.pixelOrigin_ = new google.maps.Point(128,128);
this.pixelsPerLonDegree_ = MERCATOR_RANGE / 360;
this.pixelsPerLonRadian_ = MERCATOR_RANGE / (2 * Math.PI);

The Projection.fromLatLngToPoint() method:
YandexProjection.prototype.fromLatLngToPoint = function(latLng) {
var me = this;
var point = new google.maps.Point(0, 0);
var origin = me.pixelOrigin_;
var siny = bound(Math.sin(degreesToRadians(latLng.lat())), -0.9999, 0.9999);
point.x = origin.x + latLng.lng() *me.pixelsPerLonDegree_;
var exct = 0.0818197;
var z = Math.sin(latLng.lat()/180*Math.PI);
point.y = Math.abs(origin.y - me.pixelsPerLonRadian_*(atanh(z)-exct*atanh(exct*z)));
return point;
};

And The Projection.fromPointToLatLng() method:

YandexProjection.prototype.fromPointToLatLng = function(point) {
var me = this;
var origin = me.pixelOrigin_;
var lng = (point.x - origin.x) / me.pixelsPerLonDegree_;
var latRadians = (point.y - origin.y) / -me.pixelsPerLonRadian_;
var lat = Math.abs((2*Math.atan(Math.exp(latRadians))-Math.PI/2)*180/Math.PI);
var Zu = lat/(180/Math.PI);
var Zum1 = Zu+1;
var exct = 0.0818197;
var yy = -Math.abs(((point.y)-128));
while (Math.abs(Zum1-Zu)>0.0000001){
Zum1 = Zu;
Zu = Math.asin(1-((1+Math.sin(Zum1))*Math.pow(1-exct*Math.sin(Zum1),exct))
/(Math.exp((2*yy)/-(256/(2*Math.PI)))*Math.pow(1+exct*Math.sin(Zum1),exct)));
}
if (point.y>256/2) {lat=-Zu*180/Math.PI}
else {lat=Zu*180/Math.PI}
return new google.maps.LatLng(lat, lng);
};

so, you can tell me, what am I doing wrong?

Add http://
function(coord, zoom) {
		return "http://vec0"+((coord.x+coord.y)%5)+".maps.yandex.net/tiles?l=map&v=2.16.0&x=" + 
coord.x + "&y=" + coord.y + "&z=" + zoom + "";
	}

In the end do not write ,

In Global scope you have to add two functions
function atanh(x) {
	return 0.5*Math.log((1+x)/(1-x));
}

function bound(value, opt_min, opt_max) {
	if (opt_min != null) value = Math.max(value, opt_min);
	if (opt_max != null) value = Math.min(value, opt_max);
	return value;
}


The Projection.fromLatLngToPoint() method
and
The Projection.fromPointToLatLng() method
starts with function , you do not enter
YandexProjection.prototype.fromPointToLatLng =
or
YandexProjection.prototype.fromLatLngToPoint =

And note: Yandex.Maps API resticts using it's tiles without API.
May be you should use Zh YandexMap extension

Thanks a lot.

now yandex map can be loaded

so Yandex satellite or hybrid tiles can`t be loaded on Zh GoogleMap?

and if so, is it possible to load Google satellite or hybrid tiles with Zh YandexMap?

Read Yandex Maps API description about using.
And read Google Maps API description.

You can visit yandex maps club and search answers for you question.
You are not allowed use tiles without API. It is as for Yandex, as for Google. May be I mistake :P

As for using Google's tiles in Yandex. This task was solved in yandex maps club. As in google maps - you have to use projection.

Zh YandexMap now doesn't support user map types, as a projection too. It will be done in future releases.

I think you just decide what API you want to use.
Google's API have more features. Yandex - has PMAP
