Did anyone else see this? would be great if it was available for more phones!!

Enjoy

It's also near useless.

This is why it will work with very few phones and only with latest iPhone 3GS

uses the gps, accelerometer, and the compass of the new iPhone 3GS

A compass is only a very rough guide, because of magnetic variation and also local objects like the the steel pole for the dish, an Oil tank or Gas Tank.

It's no substitute for a Satellite meter. Most experienced installers I know have spectrum analyser and can recognise most satellites at once from the spectrum.

I've installed Microwave links and sat dishes over 15 years and I can't see any real value to this.

How? surely if say take the video for example you arrive at a site and they want x,y,z you could see usingit if trees are in theway and what they will get?

Or am i missing something?

A piece of folded paper will tell you that.

stop being dry and just embrase it, its a great piece of kit.

The dishpointer site will work on windows mobile using opera or skyfire browsers, not quite the same but decent as a rough guide

Or indeed on Archos 605wifi, Archos5 3G, Most nokia Smart phones (basically Nokia version of Safari) or nearly anything else.

I use an off line Windows App from www.smw.se

Nice little app that!

Also there is Tracker on lyngsat

http://www.lyngsat.com/tracker/astra2a.html
Click on your Location for Azimuth & Elevation.

72E to 0 degrees Satellites here http://www.lyngsat.com/tracker/europe.html
0 to 61W here http://www.lyngsat.com/tracker/atlantic.html

Most people limited to 42E across to 58W due to Elevation. Also not all visible satellite have beams pointed such that any reception exist in Ireland.

Check penultimate Right Column (Beam) Here http://www.lyngsat.com/intel9.html to see what I mean.

These links let you access the Frequecies and Beams...

Note that dish sizes are for "good" elevations (more than 20 degrees), clear Sky and full power on the Transponder with FEC 3/4 typically.
ANY of the following means a bigger Dish (they add, so 3 of them is a Much bigger Dish)

• Low Elevation (< 20 degrees. Note that less than 10 Degrees is very difficult and needs a much larger dish/ clearer open space)
• Rain
• Worse FEC (i.e. 7/8 as used on Feeds)
• Lower power on Transponder (Uplink dish can be maybe 4.8m and not 5.6m and the rent is cheaper. OB feeds tend to be lower power, 90cm to 2m dish).
• DVB-S2 or higher modulation than QPSK
• Wider bandwidth Transponder.

A spectrum Analyser with BER metering for DVB-s and DVB-S2 is the ultimate dish alignment tool and tells you where unlisted Transponders are without an unreliable and slow "blind search". Ordinary Spectrum Analysers won't tell you the symbol rate directly though, just the frequency & polarity, though if it's a meter for DVB-s/DVB-s2 it will then let you search for SR. Still a lot faster than a basic sat receiver "Blind Search".
