Dear ROS Users,

I'm pleased to announce the release of ROS documentation and source code 
for the swiftnav_piksi package.

This package is a ROS release of a driver for Swift Navigation's Piksi 
<http://swiftnav.com/piksi.html>__ RTK GPS receiver module. A pair of 
Piksi modules connected by a wireless link provides the location of each 
receiver relative to the other with accuracy as good as a couple of 
centimetres when there's a clear view of the sky. In addition, each 
Piksi module provides its location with typical GPS accuracy (about 3 
meters). Often, one module is a stationary base station, which may 
optionally be located at a surveyed point, while the other is mounted on 
a rover and provides ROS navigation software with a highly accurate 
position relative to the base station.

RTK GPS has been around for a long time, however the Piksi devices hit a 
new low price point at under $1000/pair.

The documentation is at http://wiki.ros.org/swiftnav_piksi, and source 
and the standard github bug lists etc are at 
https://github.com/PaulBouchier/swiftnav_piksi.

Enjoy.

Paul Bouchier
