A74 Series S-Band Telemetry Transmitter (STX)
Original ADDNICS S-band nanosatellite transmitter with QPSK/OQPSK modulation, first flown on SPRITE-SAT (2009).
Description
The A74 STX is ADDNICS's original S-band telemetry transmitter, developed for nanosatellite platforms. It supports QPSK/OQPSK modulation with Intelsat IESS-308 encoding and was the first ADDNICS transmitter to achieve on-orbit heritage, flying on Tohoku University's SPRITE-SAT (RISING) nanosatellite launched in 2009.
