Constellations of small satellites have a promising use in satellite remote sensing or satellite communication. Launching several small satellites at the same time with one vehicle is a good way to keep the budget of the whole project under control. Multi-payload adapter is an important equipment on the launch vehicle to carry those small satellites during the rising phase and shoot them into their own trajectories during the orbiting phase. The paper studies the relations between the demands of small satellites launching and the multi-payload adapter designing. Also the paper illustrates the necessity of putting the multi-payload adapter into a project and the necessity of researching on the multi-payload concurrent experiment.

The technology of data transmission from spacecraft of remote sensing of the Earth to reception points on the ground has certain disadvantages such as the inability to quickly receive remote sens-ing data and the need to store large amounts of information on board. The technology of data re-transmission from remote sensing satellites through geostationary satellites retransmitters Luch to the reception points on the ground has the following disadvantages: the inability to quickly receive data when the remote sensing spacecraft is in the central part of the Western Hemisphere and the need for early planning of retransmission sessions. The article presents advanced concepts of com-munication organization and algorithms for establishing connections between the spacecraft and the point of data reception and transmission via a geostationary satellite repeater. The concepts are based on the following modern technologies: the availability of inter-satellite communication lines between geostationary satellites retransmitters that transforms this segment of communication net-work into a transport digital network for data transmission; the application of network technology for data flow routing that enables data transmission in an automatic mode; the application of auto-matic technology for establishing connections between remote sensing satellites and geostationary satellites retransmitters that transforms the ground reception point into a subscriber of the transport digital network by analogy with mobile network.

Forward Error

Micro satellite application for remote sensing in this time has been expanded and particularly supported by growth of electronics component that low power and small size. Large amount of image data, less of contact time and limited satellite’s power obliges of efficiency mechanism design to assured data satellite communication is accepted properly by earth station. Various of scenario of data transmissions on micro satellite have been developed in order to ensure all data that taken by payload can be delivered and accepted by station earth truly. Forward Error Control Coding or Forward Error Correction method is mechanism that added redundancy bit to delivery data with a purpose to improve error correction of received data. FEC performance can be known by compare of different value of Eb/N0 needed for Bit Error Rate (BER) in common without FEC. In this research conducted simulation performance FEC Reed Solomon by undertaking change of beet amount per symbol, code length and code ability in repairing symbol error. Simulation Result shows getting smaller code rate that used then ever greater code reinforcement. The simulation using forward error control coding Reed Solomon for data transmission remote sensing results code RS(255,223) have best performance with coderate 0,874 and coding gain 3,4dB on value of BER 10-4.

This paper introduces the implementation of space remote sensing and detecting systems of oceangoing ships as an alternative to the Radio – Automatic Identification System (R-AIS), Satellite – Automatic Identification System (S-AIS), Long Range Identification and Tracking (LRIT), and other current vessel tracking systems. In this paper will be not included  a new project known as a Global Ship Tracking (GST) as an autonomous and discrete satellite network designed by the Space Science Centre (SSC) for research and postgraduate studies in Satellite Communication, Navigation and Surveillance (CNS) at Durban University of Technology (DUT). The ship detection from satellite remote sensing imagery system is a crucial application for maritime safety and security, which includes among others ship tracking, detecting and traffic surveillance, oil spill detection service, and discharge control, sea pollution monitoring, sea ice monitoring service, and protection against illegal fisheries activities. The establishment of a modern sea surface and ships monitoring system needs enhancement of the Satellite Synthetic Aperture Radar (SSAR) that is here discussed as a modern observation infrastructure integrated with Ships Surveillance and Detecting via SSAR TerraSAR-X Spacecraft, Ships Surveillance and Detecting via SSAR Radarsat Spacecraft and Vessels Detecting System (VDS) via SSAR.

Background: Space technologies have been used in each aspect of mankind’s life, including health. The United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS) has instigated several programs to address how space technologies can contribute to global health.Aims: This article deepened the understanding of how space technology contributes to global health and identified how it may be used in the context of COVID-19.Results: This research identified four different domains of space technology that can or may contribute to global health, which are remote sensing, global navigation satellite system, satellite communication, and human space flight. Generally, these four domains can track disease outbreaks and help mitigate its spread such as by minimizing patient contact with medical personnel. They also keep daily activities such as communication and work afloat. Future developments in space technologies may prove to have an even bigger role to minimize spread.Conclusion: Space technologies are invaluable in helping healthcare personnel and governments track the disease’s sources and spread. Also, they can identify locations with the most damage, and thus immediate actions can be taken. Keywords: geographic information system, infectious disease, outbreak, remote sensing, space technology.
