Problem with object use geo location

I use to Wikitude SDK Javascript

I have used GeoLocation show object represents a location in the earth's three-dimensional space. The Object has been displayed but when I move the camera, the object also is moved follow. I don't know why?


code here:

var locationSun = new AR.GeoLocation(20.9757, 105.8397,10);

        var sunImg = new AR.ImageResource("assets/Sun-icon.png");
        var indicatorImg = new AR.ImageResource("assets/indi.png");

        var sunSize = 3;

        var sun = {
            name: "Truesure",
            distance: 0,
            location: locationSun,
            imgDrawable: new AR.ImageDrawable(sunImg, sunSize),
            size: sunSize,
            description: "The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields.",
            mass: "2&nbsp;10<sup>30</sup>&nbsp;kg",
            diameter: "1,392,684&nbsp;km"

        /* put sun, planets (and pluto) in an array */
        this.planetsInfo = [sun];

        /* create helper array to create goeObjects out of given information */
        var planetsGeoObjects = [];
        for (var i = 0; i < this.planetsInfo.length; i++) {

            /* show name of object below*/
            var label = new AR.Label(this.planetsInfo[i].name, 0.3, {
                offsetY: -this.planetsInfo[i].size / 2,
                verticalAnchor: AR.CONST.VERTICAL_ANCHOR.TOP,
                opacity: 0.9,
                zOrder: 1,
                style: {
                    textColor: '#FFFFFF',
                    backgroundColor: '#00000005'

            /* drawable in cam of object -> image and label */
            var drawables = [];
            drawables[0] = this.planetsInfo[i].imgDrawable;
            drawables[1] = label;

            /* Create objects in AR*/
            planetsGeoObjects[i] = new AR.GeoObject(this.planetsInfo[i].location, {
                drawables: {
                    cam: drawables
                onClick: this.planetClicked(this.planetsInfo[i])


        // Add indicator to sun
        var imageDrawable = new AR.ImageDrawable(indicatorImg, 0.1, {
            verticalAnchor: AR.CONST.VERTICAL_ANCHOR.TOP

Hello Vu,

Please refer to this tutorial 'How to work with GeoLocation Class' to see if the information provided there help with your issue.

thank you very much. 

sorry, but I have added one question

example var location = new AR.GeoLocation(47.805634, 13.045209);
when I allocate variable location with  GeoLocation. I see that the Object Earth is no fix position, the position of its has moved change. please see link youtube

 why has position of its changed?

Hello Vu,

Please refer again to the tutorial I have placed in the forum post above. There, it explicitly says that

When you are testing GeoLocation features, you need to keep in mind that the results could be greatly influenced by these two factors:
  • Testing inside. This could deteriorate the performance and therefore, it is always advisable to test outside. GPS provider.
  • You need to make sure that the GPS provider you are using is accurate enough and it does not influence the performance. So, if you are testing with an old device then this could influence the results.




I'm in the same situation. I have placed a 3d model with geolocation, but it moves as i move towards it....

Did you find a solution for this?

I have tested it outside with an iphone 6+...

Thank you in advance.

Hi Luis,

There are no changes in regard to the accuracy and sensibility to the signals - in case you get a locationUpdate once you move twoards the model it might move - depending on the accuracy and frequency of the update.

Would our Instant (Markerless) Tracking feature work for your use case - you can find samples in the sample app and work together with the technical documentation to try it out.

Thx and greetings


If you get a locationUpdate when you walk toward the model, it may shift depending on the update's precision and refresh rate, but otherwise, the accuracy and sensitivity to the signals remain unchanged.

If you're curious as to whether or not our Instant (Markerless) Tracking function is suitable for your needs, you can try it out by examining the samples provided in the sample app and utilizing the information provided in the technical documentation.
