show satellite's cartographic coordinates in real-time

Hi,
I’ve visualize several satellites with .czml format. But I wanna know how to show the satellite’s position values with mousemove?

The Cesium code exmple shows how to show the real-time position values when the mouse moves on the ellipsoid earth. But the satellite is always flying overhead the earth.

So what should I do if I want to show the real-time position values of satellites?

Thanks for any help.

Hello Erin,

See our picking demo for how to pick an entity: http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Picking.html&label=All

Then once you have the entity, you can get the position at the current time with var cartesian3 = entity.position.getValue(viewer.clock.currentTime);

Then you can convert it to a cartographic with viewer.scene.globe.ellipsoid.cartesianToCartographic(cartesian3);

Let me know if you’re having trouble and I can put together a code example.

Best,

Hannah
