We unfortunately had a slight delay due to lack of hardware, and were on a software only development cycle for several weeks.  I am happy to report that the hardware has almost all arrived, and we will be beginning the construction of the flight hardware within the next few weeks.  The state of the software is coming along well, with the software for the flight computer being 95% complete, with only minor interface tweaks to be made.  We are also proceeding with a graphical interface for ground computer control, and have completed roughly 60% development on that.   Hardware is currently 80% designed and ready to be built, with some small changes to be made, as well as another possible instrument to integrate.  
We also completed some basic range data with the wireless system (XBee 900 mhz) to determine ranging.  We were able to achieve approximately 750 foot NLOS test with good results (with a low gain wire antenna) and will be conducting a LOS test shortly.
