MIL-STD-1553 is a military standard that defines the electrical and protocol characteristics for a data bus. This bus is being widely used in aerospace industry. This standard was implemented at SRDC-L basically to be used in Prototype Paksat-1R. The components used in this bus are restricted items and very difficult to procure. Therefore most of the hardware was implemented using components which are easily available from the market. The software was also developed and successfully tested with the hardware. The paper presents the introduction to the electrical and protocol characteristics of the data bus along with the steps to be taken to design and develop the hardware and software for the bus. System level diagrams and top level software design are also provided. |
