h3. Keflavík Airport Weather Service

h3. Gas selection

Gas used for test flight will be Helium as decided by Joe and Ragnar at a meeting on 7.2.2012

h3. Electronics

The test flight will have the following electronics

* Camera - A GoPro HDHero2 has been purchased.

* GPS tracker - Currently the "Spot":http://www.findmespot.eu/en/ is the 

* Altimeter - Being a recent addition not much research has been made into this. If launched from Keflavík Airport, the Weather Service can provide us with a radiosonde wich has this function. As well as high altitude GPS tracking up to the "cut down" point. 

** Appears that there are some low cost options

*** Zlog makes one that goes to 32000m http://www.hexpertsystems.com/products.html

*** For higher, we would need to build something like this http://www.thefintels.com/aer/atom_altime

*** Which uses this chip Honeywell ASDX http://datasheet.octopart.com/ASDX015A24R-Honeywell-datasheet-29814.pdf

*** Sparkfun has a barameter similar to the Zlog, but needs a recorder. http://www.sparkfun.com/products/9694

h3. Balloon

A 3000 gr. balloon will be used for the test flight as decided by Joe and Ragnar at a meeting on 7.2.2012

h3. Retrieval

I contact the LHG(Coast Guard) and asked them for help to retrive the sword after launch. They were willing to do that, but ongly if the other helicopter companys in Iceland were not intrested to do it, or do not have the equipment to do it, since the sword will maybe land on sea. 

The helicopter companys that i know are:

-Vesturflug ehf(Blue West Helicopters)

-Norðurflug

-Þyrluþjónustan

-Vesturflug ehf

If you know some other, please add it here above.

LHG contact:
