UPDATE: This app has been superseded by the new DishPointer AR Pro and DishPointer Augmented Reality apps which are far more superior than this app. Please look for these apps in the iTunes store. Alan

DishPointer LOS is an application for your iPhone that will help you see if you have a clear line of sight to the satellites in the sky!



Check out any line of sight issues with this iPhone App. Just point your iPhone at the sky, tilt it until you get the right angle and then switch on the the camera preview. If there is a clear sky right at the center of the screen, you’re good to go. Simple but very effective.

The DishPointer Line of Sight Application can be downloaded from the Apple iTunes Store by CLICKING HERE.

If you have any questions about the DishPointer Line of Sight application please post them in this thread.

How to use DishPointer Line of Sight:


  • Once you know if in which direction to point the dish (see the DishPointer Maps or DishPointer Compass iPhone apps), hold your iphone up with the camera facing the sky. The angle at which you’re holding it is displayed on the screen. In addition, the two satellite positions which have this elevation at your location is given.
  • After you’ve found the right angle, hold the iPhone still and tap the camera button and focus at the center of the screen. In the camera preview, if there are no obstacles at the center of the screen, there are no line of sight issues. If there is a tree or a building, you will need to find another location for your dish.
  • If you wish, you can then take a picture and a target cross is overlayed at the center to verify clear line of sight to the satellite.

This is for any iPhone. You should first see a white screen with the degrees in a box, underneath satellite positions matching the elevation and a camera symbol. Once you got the iPhone tilted, tap the camera symbol and look at the center of the screen. If there is a clear sky, you are ok. No need to go much further than that, though if you like you can take a picture and the target cross gets superimposed on the picture (not the live camera).

Initially, the target cross was part of the live camera preview but that got rejected by Apple. It would have been better but think it's still helpful as it is.

Is there a way to store the photo in the phone so I can attach it to my sight survey form? Also is there a way to make sure the cross is on the satellite do to the fact that I have a very shaky hand.

It would be possible to store the picture but not with the cross on top. If that's still useful, I'll add that feature.

If you also want the cross, you could take a screenshot of the display: Just press the power and home button at the same time. That picture gets saved in your album but the resolution won't be that great, just 320 x 480.

You need to hold the phone still when pressing the camera button and then again to take the picture. It would be a lot better if the cross and the elevations were on top of the live camera preview but as said before, not allowed at the moment.

The amount of difference even that high up is almost nothing, maybe 0.0000000001% considering your aiming at a satellite which is the size of a small car that is 22,500 miles in the sky.

A couple feet off the ground even 28 stories is not going to make a difference. :)

After reading some of the questions I understand a little bit. I agree it would nice to have the red crossbar so you can take a live snapshot. The zoom on the camera would be great toget a better idea to see the spot. Maybe you can work it in a upgrade? Can you have your own site for the live crossbar? What do you think of the zooming of the camera idea ? Is new app that is coming out work with 3G?

Thank you

The iPhone camera does not have zoom. Anything else is just enlarging the area.

I was very excited when I learned of this innovative app. I downloaded DishPointer LOS with the understanding that it would provide features similar to an enhanced electronic sighting inclinometer and sighting compass. The app is novel in the current stage of development, but not a replacement for either sighting function when determining LOS for a specific satellite. It is difficult to determine the azimuth for a specific satellite when only the east and west satellite positions are displayed.

Would it be possible to add the orbital slot position and named satellite for the center of the screen or an overlay of the arc with the visible and named satellites? A photo feature should be available to document the "LOOK ANGLE " complete with the satellite information overlay.

I see much potential for the app in replacing a sighting inclinometer/compass, providing documentation of LOS for installers and becoming a required install sign- off document.

Thank you for your development of these next generation installation tools. We look forward to future updates!

App is good ty, need elevation to move to get the elevation in the right place...
Elevation is fixed, it's not supposed to move. That's where the satellite is, in absolute terms.

You can take a picture by pressing the power and home button at the same time. The pic will then be in your camera roll.

It's a completely new concept. The previous app required you to hold the iPhone exactly at the same angle as the satellite and would display that information to you ("you are now holding the phone at the same angle as the satellite and the satellite is right at the center of the screen").

Now, it doesn't matter at which angle you hold the iPhone as long as the satellite is visible on the display. You will see as you move and up the iPhone that the satellite dot always stays at the same spot on the live image ("There is the satellite, period"). That's the whole beauty of this app, it kinda gives you magic eyes, let's you see things which you couldn't see before.
