This system generates all timing and control signals required for payload operation and acquires telemetry data of health monitoring parameters of Payload.
It is connected to the spacecraft computer serially. The mechanical structure, housing the electronics was realized by a stack of firmly held trays, each of which was fabricated by milling a single piece of solid aluminum alloy 6061TS.
The PLC too, like others, was successfully subjected to Flight Model Environmental 168 hour burn-in testing.
Ambimat’s layout design was a mix of digital and RF components on single six layers PCB. The digital section comprised of an FPGA along with associated buffers, drivers etc. The RF section consisted of two-way 90-degree power combiner/splitter, SPDT Switch and Power Amplifier for RF signal for transmission.
The modulator was successfully subjected to 168 hour burn-in environmental testing.
