Low power system with built in GPS, WiFi?

[Andy Ruhl <acruhl%gmail.com@localhost>]

I'm currently using a Raspberry Pi Zero with a camera for something
(using raspbian), and I want to do something similar but I'm hoping to
get onboard GPS. I want to run it on a battery.

Also if the WiFi adapter could do hostap, this would be a bonus.

Does such a thing exist?

A USB camera could be used but I've never done anything with cameras
and NetBSD, is it possible?

The goal is to be able to stream video to another WiFi device, and
possibly log GPS location.

Thanks.
