How much daily human input is needed to keep GPS satellites and service operational?
Cheesecakegrease asked:
I’m wondering if in the event of a massive natural disaster or disease pandemic how long would your basic handheld GPS unit still be functional. And also how would this affect cell phones or are they totally separate.

How much would the initial cost of GIS software and GPS instrumentation to start a small Mapping business?
Kiah D asked:
Trying to start a small GIS business on my own… already have the LLC and domain name and what not..have also been networking and possibly have some small contracts potentially lined up. I am trying to focus on things like utility mapping or something, but I could definitely broaden out. What programs, extensions, and GPS instrumentation would it take for me to get started and what do you think the intitial cost would be?

Thanks a ton!
How does a metal housing affect the signals on a GPS device?
k1mj asked:
I am designing a portable small GPS device and I would like to use a tough scratch resistant material – such as aluminum , titanium alloy or steel – for the main housing. Is it possible to use any of these or I’m better off using ABS.
I would like to if there is any difference in terms of signal reception if I use aluminum titanium alloy or steel ?

How many meters do the GPS satellites wander around?
Barney asked:
The satellites wander around and are stabilized with short “burns” of rocket fuel. How many meters do they wander before the ground station orders them to move? I would also strongly suspect (correct me if I am wrong) that the absolute position can be corrected in software to some extent. but with accuracies on the ground of 5 meters or so, I would think the satellites would have to be pretty stable. Yet on the other hand it’s hard to imagine those things being nailed to the sky.

Does a GPS receiver report the position of the receiver chip, or the position of the antenna?
Mark asked:
If a GPS receiver is connected to a remote antenna, is the position reported to be the location of the receiver or the location of the remote antenna?
