Point shapefile XY coordinates problem with ArcGIS online

[KarolinaKorzeniowska]

I have three dataset: two rasters and one point shapefile which I would like to add to my map in ArcGIS online. All of data have the same projected coordinate system, however after importing them to ArcGIS online map the points are shifted few meters to south-west with respect to my raster data. What should I do to correct it? Which reference system should I use to be sure that my data are displayed correctly?

When you view the data in ArcMap does it align correctly?

What coordinate system is this anyway?

[KarolinaKorzeniowska]

In ArcMap everything works fine. The details of the spatial references I am using are attached below.

Data Type: Shapefile Feature Class
Geometry Type: Point
Coordinates have Z values: No
Coordinates have measures: No

azimuth: 90.00000000
longitude_of_center: 7.43958333

What is the extent?

I believe that you should re-project Project—Help | ArcGIS Desktop  this data to GCS_WGS84 before uploading to AGOL.

"Projected Coordinate System: CH1903_LV03", is based on GCS_CH1903 and will require a datum transformation as well. There are several available in the system.

Could you also attach a screenshot of the spatial extent of the point layer from ArcMap (Layer Properties > Source)?
