Operating Systems for Snow White

SOWER is currently using the so-called TMAX system.

In this system, Vaisala RS80-15 or RS80-15H radiosonde is modified and used as the PTU sensors and the transmitter. The TMAX-C interface board processes the data from Snow White, En-Sci ozonesonde (1Z ECC), and RS80 PTU, and sends them to the RS80 transmitter.

The ground receiving system consists of a 400-MHz antenna with an amplifier, receiver (e.g., icom IC-R8500), modem (Kantronics KAM98), and PC. An MS-DOS based software STRATO.EXE developed by Dr. Holger Voemel is used as the PC software.
