Doesn't track on a airplane

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Take a flight
2. Start tracking
3. See what happens when you are in the air

What is the expected output? What do you see instead?
I expect to save a track of my flight. Instead i see hole extrapolated by line.

Which Android device are you using?
Sony Ericsson xperia mini pro

What version of Android are you running?
1.1.A.0.8

What version of the Open GPS Tracker are you running?
How can i find this information?

Please provide any additional information below.

I am sorry for multiple issues. There was a problem with the bugtracker.

In the settings there is the sanity option, this will filter out speed and 
altitude spikes. These spikes are abnormal values which in a plane are actually 
realistic. It would improve tracking if you disable this option.

The GPS signal will most likely not penetrate a normal airplane hull or be 
available at all when the phone is in "flight mode". How was the available 
signal during flight?

Hi,
The signal was available in both trips to and back unil some moment when we 
have reached particular altitude and speed i think.

Signal was available inside the hull and the phone was in flight mode. I have 
attached .kmz file for you to look at. Could you please confirm the option you 
siggested will work for future flights or we need additional release?

> this will filter out speed and altitude spikes
Usually, plane monitonically increases/decreases speed and altitude. I don't 
think it's a spike.

It could be a feature rather than a bug.
I think most normal consumer GPS-devices can't handle high speeds (500km/h and 
above).
For example the 'Sony gps-cs1', in the manual it says that tracking over 500 
km/h isn't possible (http://pdf.crse.com/manuals/2688548321.pdf page 11 - 
sorry, I couldn't find an english manual)

As others have mentioned, unchecking the sanity check will allow OpenGPSTracker 
to record high speeds, which are in most circumstances "bad data" that you want 
to be filtered out, but in the case of airplanes are not.

Getting a GPS signal within an airplane is also difficult - the phone needs to 
be able to reach several GPS satellites, and can't do so through the metal body 
of the plane very well - I've found that you have to keep the phone very close 
to the window for it to pick up sufficient satellites.

I think this issue can be closed, it can be resolved by using the existing 
sanity check option.  I can confirm that with that unchecked and my phone near 
the window, I was able to record a GPS track from a plane just fine.
