23feb2012amanda/patrick: new gps works albeit slow acquisition. quesitons is versions differences. also reacquistion speed. amanda: tm rate ok for 20 if 1/sec cadence wisp: try wooden bar, then decide. wisp: report on salmon reading; also report on scale lengths of ct, mascoma, and upper white. pooh sticks. solar panels: have "dave" panel layout. perhaps change series combo. also connector. then reiterate with jason. jon: river: "real" river. with dimensions etc. cushman-roisin. flow of a river depends on undersurface. flow goes to zero on sides, so faster in middle. but actual flow depends on understructure. for constant flow, need only one payload. number of payloads equals width/(structure size). so ct river will be boring (for first logistics). more interesting would be mascoma or upper white. re flow modelling. instead of a river, generate a random flow field. still want a flowing tube of water. gradient scale length (B/(dB/dx)): number payloads per gsl per dimension? how many for some random terrain. small rockets: look into 3-d printing. |
