> $3k/year for each 1kg added to the plane
sorry, offtopic, but this is an interesting number. Do you have a source for more on this? Most of the search hits I can find are discussing economics of spaceflight.

Usually you find these kinds of figures in articles about 3D printing aircraft parts. For example, "By reducing an airplane’s weight by just one kilogram, an airline can save $1,300 in fuel costs per year, according to the [2011] IBISWorld report." [1] The 2014 report can be purchased here [2]. Of course, these numbers will depend on the kind of plane and its utilization, as well as fuel costs.

I don't understand why such a difference between what you are saying and a portable SPOT device [1] which is pretty much standard for extreme sports nowadays. A SPOT device is only 114g, tracks every 2.5 minutes, and runs on batteries for days. $170 for the device and $200 for the service per year.
Actually if passengers start carrying these devices (while sitting next to the window) that's already a solution.
In contrast, since MH370, Inmarsat has changed the time period for handshakes with their terminals from one hour to 15 minutes. Cost: $0.
