CTU controls the newest powering up, time sequence, watching techniques, and you can arrangement of the SAR cargo
SAR Electronics Subsystem
In the form of the new communications coach, the newest Manage and you will Timing Tool (CTU) obtains requests from the satellite system and you can sends condition monitoring study to help you it. In the meantime, the AIU monitors the newest performing county of one’s electronics subsystem and you may new operating county of the antenna subsystem through a professional studies bus.
The benefit Distributor Tool (PDU) directs the working platform energy coach to all the units of SAR electronics subsystem, and additionally AIU and TGCUs of antenna subsystem, and you will efforts upwards the unit underneath the power over the new CTU and you may satellite platform. As a result of the some means of your own secondary power supply, the DC-DC converters is thrown from the other tools in lieu of being build regarding PDU.
Predicated on a top balance oscillator, a frequency Creating Device (FGU) produces new synchronous resource volume indicators expected by the other systems. According to the heartbeat width, bandwidth, modulation mountain, and you will time manage received throughout the CTU, the fresh Linear regularity modulated rule Creating Unit (LGU) employs in the-orbit genuine-day calculations generate the fresh new chirp signal waveforms and delivers they towards the TGCU and you can Internal Calibration Product (ICU) once modulation, up-sales, selection, and you can amplifying.
