The GPS part is plausable, but the antenna and battery required is
I have a board from a weather balloon that takes the GPS signal,
partially decodes it to get the doppler shifts and then FM telemeters
that to a receiver, the board is two stacked thin layers of double
sided RF pcb and is the size of a deck of cards, weights maybe 30
grams, draws just a few mA and can be done for less then 50$ a unit,
however the raw decoded data isnt gonna fit into a cellular bandwidth,
nor is the amplified GPs antenna it needs gonna work under her skin.
Keep in mind that this receiver just basically relays the IF signal of
the GPS to a decoder and does no math or sync of the spread spectrum
on its own.
The weather ballon uses a 19 volt 250 mA salt water activated battery
about 10 cm by 10 cm by 10 cm.
My bet is the joker thinks he can use the cell sites for
triangulation and is thinking that silly girl is gonna let him stuff
a pretty good sized box containing a analog cell phone and a lithium
battery into her chest or stomach cavity, where she can feel it every
time she moves. I'll bet it gets removed after two days if it is ever
Even though it could be made pacemaker sized, the 4-6" whip required
isnt gonna be something I want implanted in me, nor do I want a
playing card sized patch antenna in the top of my skull.
