Why doesn't my gps work on my camel in bagdad?

its probably not properly grounded

cause a GPS is for a car not a animal

What animal has two humps and is found at the North Pole?
Your camel.
GPS didn't work !

And

Camel Tracking in Qatar
Camels are very mobile animals and
sometimes can move more than 100
km or more from base.
It is difficult to quickly locate the
missing camels without the help of
technical equipment.
Human beings use GPS-mobiles.
Camels are not able to use it.
The other question is: Who would
charge the mobile battery?
The next important difference is,
that camels walk longer distances
from the transmitters. The radius of
a transmitter (GSM 900 MHz) is
around 10 km. In the desert there
are no relay stations.
Camel Tracking in Qatar
Our system uses VHF-frequencies
with a radius of more than 100 km.
The tracking system contains a GPS
receiver, a VHF-transceiver and a
solar powered battery, all controlled
with a microcontroller unit. It works
self-sufficiently for several months.
How does this system work?.....
Camel Tracking in Qatar
First, one needs a VHF transceiver
with an antenna on a high rise
building or on a tower.
Ideally we recommend that, the
equipment is placed in the outskirts
of the city.
This is to avoid frequency
interference from electrical
appliances..........

Simple: There's no such place as "bagdad".
Now, if you were in BagHdad, that would be a different story! ;)
(and, yes, I'm aware that there is a "Bagdad" in Kentucky,
but, to the best of my knowledge, there are no camels there;
at least, not according to my GPS) ;)
