PULSAR-DATA compact transmitter solutions are designed for advanced missions where a high data rate downlink is required.


The low power consumption PULSAR-STX solution operates at amateur and commercial bands respectively and is user programmable within bands. The transmitter implements QPSK modulation with transmission data rates of up to 2 Mbps. It utilises an open network encoding scheme based on the IntelSAT IESS-308 specification which allows this product to be used with low-cost commercial satellite receivers.
