This SD image is a debian jessie console image with:

• a 4.1.22-ltsi-rt kernel with RT-PREEMPT patches applied
• tested on Terasic DE0-Nano-SoC Kit, other SoCKit platforms should work with appropriate dtb
• machinekit RIP-build under /home/machinekit/machinekit, all build artefacts are in place (no need to run make)
• machinekit packages are NOT installed and you do not have to!
• all machinekit build- and runtime required packages ARE installed.
• /home/machinekit/.bashrc already set up to run machinekit from the RIP build directory.
• one known-to-work configuration with hostmot2/onboard FPGA support is: machinekit/configs/hm2-soc-stepper/5i25-socfpga.ini

# Intended to convert a typical radar lla and az el to a cesium quaternion orientation for CZML
# Uses numpy, transformations.py (http://www.lfd.uci.edu/~gohlke/code/transformations.py.html),
#   and ecef.py (https://code.google.com/p/pysatel/source/browse/trunk/coord.py?r=22)

    rotZ = rotation_matrix(math.radians(180+az), [0,0,1])
    rotY = rotation_matrix(math.radians(-(90+el)), [0,1,0])
    rotM = np.dot(rotZ, rotY)
    origin = geodetic2ecef(lat, lon, alt)
    origin = np.multiply(origin, 1000)
