“…The two ways both depend on foreign manufacturers, the 1553B chips are expensive and hard to buy in China, meanwhile, the size and power consumption of 1553B interface circuit are large. Therefore 1553B bus low power technologies have caused the interests of the engineers both at home and abroad [4,[9][10][11], which is important for development of the Chinese defense and space industry.…”

“…This method is based on the physical medium and transceiver replacement, having no influence on the 1553B bus higher level protocol. There are two mature ways for this method now, which are based on the RS485 transceivers [4] and infrared technology [9][10][11]. Some key parameters of RS485 bus and 1553B bus are compared in table I, we can see RS485 bus can perfectly match with 1553B bus in many parameters.…”

“…Infrared communication comparing with radio frequency has the advantages of lower power consumption, prices and anti-electromagnetic interference, and high secrecy. The Spanish national space agency INTA has been working on the intra-spacecraft infrared communications for 10 years, and has gained fruitful achievements in the space application [10][11]. The INTA and NASA have rich experiences on the design of 1553B bus based on infrared technology [9][10][11].…”

“…The integrated IR chips are simple to interface digital chips and easy to use, which makes it widely used in the ground tests and demonstrators. But in the later onboard applications, it is necessary to use Rad-Hard components [11] to design IR transceivers. Table II illustrates the performances of the three 1553B low power technologies.…”

MIL-STD-1553B bus is widely used in military and space missions nowadays for its high reliability and efficiency. Minimizing mass, size and power is one of the prime objectives for space missions. The problems of mass, size and power in implementing 1553B bus systems limit its applications in small satellites. To solve the preceding problem and realize the satellites miniaturization, three low power technologies of 1553B Bus are proposed in this paper. The low power concepts are based on mature technologies and components, such as large scale programmable specific integrated circuits, low power bus transceivers. The design of ASIC (Application Specific Integrated Circuit) or SOC (System On a Chip)chips including 1553B IP Core and related peripheral functions, the design of 1553B bus based on RS485 transceivers, and the design of 1553B bus based on infrared communications are introduced in this paper. The three designs are tested and verified rational by system simulation and experiments. Finally, a promising low power design of 1553B Bus for Chinese satellites is presented. The 1553B protocol is realized by ASIC or SOC chips including 1553B IP Core and relevant peripheral functions, and the physical layer is realized by RS485 transceivers. Design of 1553B bus based on infrared communications will also be used widely in some special applications, for example in the small and nano satellites.Index Terms-Low power, MIL-STD-1553B, IP core, RS485 bus, Infrared communication.

“…Moreover, some of them increase its detecting area thanks to an epoxy lens implemented on detector, that in two of the photodiodes has also a band pass IR filter incorporated. The degradation measurement of performances of optoelectronics devices requires a very accurate way of positioning and fixing components [14]. The analysis of these performances is completely dependent on the pattern of the light that they receive (photodiodes) and the measurement of the light they emit (LEDs).…”

LEDs and photodiodes (PDs) suitable for OWLS were irradiated with 52 MeV protons and up to 2.8 1012 p/cm2 (in 5 steps). Electrical and optoelectronics parameters have been characterized during the test (characteristic I-V curve, dark current, PD responsivity and LED optical power) results about degradation and are reported. Also, the differences in degradation rate for several biasing conditions during irradiation have been studied.
