Abstract
ABSTRACT
The payload of the low earth orbit (LEO) satellite consists of all the components that provide communications services, that is, which receive process, amplify and retransmit information. The payload can be divided into two distinct parts: Panchromatic and multi-spectral camera (PMC), Payload data handling subsystem (PDH). The PMC camera is intended for reception of digital image of assigned areas of the Earth surface of the Earth by registration of reflected and own earth radiation. The other components in the payload make up the PDH. This includes all the components that process and amplify the uplink signal obtained from the receiving PMC before delivering the downlink signal to the transmitting PMC. This study presents an iterative simple technique to calculate the payload operational effectivenessfunction over time (using Monte Carlo simulation), and improve reliability with low redundancy.The most critical system component and their contribution values play a strong role in the identification of the weak path which leads to system failure.And propose the candidate component(s) to be duplicated as backup technique.
The work result shows how the proposed technique is high effective. Whereas the reliability and operational effectiveness 96.47% and 94.2%, instead of 90.48% and 86.2% consequently.
