GPS Motorcycle Tracking

Smart and succinct. Thanks.

 

With respect to GPS systems working in a given place, you must take into
account the antenna built into the receiver (and the quality of the
receiver itself). These components can cost quite a bit, and are likely
the ones that companies cut the quality on in order to reduce costs of
their consumer systems. Basically, a more expensive receiver is more
sensitive (better able to register highly attenuated signals coming
through an object) and a more expensive antenna will likely have more
gain.

I'm not saying that a GPS is absolutely going to work in the back of a
windowless van with a metal bulkhead, but it's not impossible. The GPS
unit would have to be a pretty nice one to even stand a chance, though.
The only way of knowing whether a given system would work under these
circumstances would be to test it (in it's installed configuration, just
putting the receiver and antenna in a metal box isn't helpful). It's
likely that the manufacturers of these systems have done this testing,
but I don't know anything about such systems capabilities.

Good summary.

 

Just as a data point, we've got Ford E250 cargo vans at work, the only
windows are the front window and a window on each of the two doors.
My eMap loses reception once you take it about a foot from the
dashboard(using its own internal antenna). Granted that the eMap is
not the highest quality gps available on the market, but its a data
point.

 

More instructive, take a GPS into a narrow canyon, and a city street lines
with four or five story buildings will do, and try to get a reading. Or as
someone else noted, under a forest canopy. The first generation of consumer
GPSrs were almost useless; they have gotten much better but there still are
no miracles. If a RF opaque material obscures enough of the constellation,
you will have difficulty getting a lock.

 

Mine works rather well inside my house...
