2nov2012range issues: (3) dave3 antenna connector was broken
(2) 9V insufficient at full power transmit
(1.5) propagation delay, other settings
(1) can't have full data rate and high power
upshot: put power diagnostics into receiver
reconfigure antenna cabling
one more range test. park street. can do this as
soon as figure out how to record. do soon. do runs, one with ascii/wizard and one with flight code. dave3 launch goals:
date??? winds good, weather bad. aiming for nov10/11 launch: peter/patrick/todd/ralph: jacob/kath recovery: jake/jon/rob bob: mech fit, waiting on uaf
batteries, need several combined packs
innards, need several new ones
spin test range issue
rate sensor
new board: prototype shows both rate sensor and compass board, presently through usb. could be xbee. memory
replacement for SD card. can write quickly, retains info after poweroff. PRAM with serial interface Solidworks thermal model
"thermal desktop" as an autocad addon; leslie expert thayer mostly solidworks; STK
ongoing; sean hill equation (zan; phil; simon) data assimilation
jon thesis: given a set of points in space with observed values, reconstruct underlying truth from limited sampling. how best to do this? simple interpolation to more fancy reconstructions: compressed sampling; neural nets; supported vector rob: p100 math methods thayer math prof; interested in L1 techniques |
