Brief description of current and future projects are presented below.

Satellite Track and Read (STaR)

STaR graphical interface

STaR is a general satellite scheduling and antenna tracking program with modular motion control and signal processing for polar orbiting direct broadcasts.

Written in Python on Gnu/Linux, the package is capable of incorporating different motion control regimes by sharing a common rotor interface. STaR can also use independent Software Defined Radio (SDR) programs to process different satellite signals. Current modules used in STaR are described in sections below.

STaR is currently driving a "maker" rig with the PI314MCG and PI314LBM boxes, a flat multi-patch L-band RHCP antenna and can read NOAA-18,19, and METOP-A,B,C satellites for available sounder and AVHRR data. STaR also drives a maritime rig retrofitted for terrestrial use and reads the same set of satellites.

Recent satellite images can viewed here and the delivery is fully automated through scripts and GnuRadio,Terrenus HRPT/CoastWatch, SSEC/Polar2Grid , and ESA/AAPP platforms.
