We are using a pair of RFM22s - the transmitter sends magnetometer (azimuth) and accelerometer (elevation) data from a LSM303 along with its output power level. The receiving RFM22 appends the received signal strength value. From there what we want to do is real time plotting on a net book. 2D seems readily achievable through either LabView's polar plots or a number of different Python plotting libraries. However what we'd really like to do is real-time 3D plotting, but we don't know the right toolchain or libraries. We know we can do it in Matlab, but that won't be in real time. Are we on the right track? Has this been done before? Should we settle for a pair of 2D plots, or can real time 3D be done? Is there interest in the community for something like this? If it is, that would place different requirements on us (economical, easy to duplicate, good documentation, open software, etc). 73, NX1U _______________________________________________ Sent via AMSAT-BB@amsat.org.
