PSAS - Meeting Notes
http://blog.psas.pdx.edu/2014/08/meeting-notes
Portland State Aerospace Society. This week Nathan showed off a couple of new results from vibration analysis from Launch 11. The carbon fiber team has decided that if they buy COTS parts for the missing pieces of the rocket they can make a late September/early October launch. WiFi does leak into 1.5 GHz spectrum, but it’s not clear if it’s the rocket or a laptop that was near the test receiver. The rocket net hub did not boot at first! Theo found the problem was an update to the ChibiOS compile flags.

PSAS - gps
http://blog.psas.pdx.edu/gps
Portland State Aerospace Society. Posts about our GPS study group. Fall term, 2014. Some GPS Success And Some Visualization. We’ve had a couple more weeks of GPS study group meetings and slowly we’re starting to catch up on how GPS works. Notably we’ve taken our test data source and updated Jamey’s old GPS FFT cross cross-correlation code. And successfully found several satellites in the noise! In addition Nathan has started doing some visualizations of basic GPS encoding:. GPS Study Group Meeting Notes.

GPS Visualization
https://natronics.github.io/blag/2014/gps-viz-1
GPS Visualization – September 2014. While following along with PSAS’s. GPS study group nights I really want to get a better visualization of what’s going on with GPS signals as they’re being created, sent, transformed, and variously mangled. Let’s start at the beginning. The L1 GPS carrier is a plain sine wave at 1575.42 MHz. Not much to look at, but here it is. GPS L1 Carrier Wave'. The transmited GPS signal uses binary phase shift keying. This is completely indecipherable! The problem is that the carri...
