Micro-Apps 2013: Understanding Probability of Intercept for Intermittent Signals
Adaptive sampling is a signal processing technique that has been widely employed in the fields of audio coding and sensor networking. A manifestation of the technique for instrumentation and telemetry applications wherein the signal is down-sampled based on frequency domain analysis is described here. The implementation of the technique at system level is explained and the hardware configuration and software flow needed to support it are illustrated. Two applications of the technique viz. data compression and health monitoring are then described in the context of aerospace instrumentation and telemetry systems. The enhancement in efficiency that it enables for data synthesis and analysis is brought out.
This paper deals with the analysis, design, manu-facturing, testing and evaluation a turbine flow meter to measure liquid propellant flow in launching rockets. Axial turbine flow-meters exhibit superior performance when used with low kinematic viscosity fluids. Under subsonic turbulent flow conditions these instruments show a highly linear behavior with very good repeatability without any additional compensation (neither hardware nor software) and they also exhibit a low pressure drop at maximum liquid flow. A 10 liter/s @ 1 bar pressure drop flow-meter designed to be used with MMH and NTO liquid propellants is exposed. Starting from the turbine's motion equations, the relative incidence of active and parasitic torques is analyzed, both in stationary and transient flow conditions. The dependence of the instrument's proportionality factor (K-factor: pulses per liter) related to the properties of the flowing fluid and turbine dynamics is evaluated in both aforesaid situations. The instrument has been assembled and successfully tested. The paper includes some abridged benchmark results.
Modern and perspective highly capable on-board networks for scientific space missions require responsiveness, determinism, robustness and durability. The SpaceWire-RT research programme aims to create communications network technology, suitable for these fundamental requirements of demanding applications. The paper gives an overview of activities in the FP7 SpaceWire- RT project consisting in the development of the new onboard communication standard - SpaceWire-RT that satisfies all requirements of space applications. The main focus of the paper is the investigation of SpaceWire-RT standard by means of the SpaceWire-RT protocol simulation. The implemented SDL and SystemC models gave an ability to validate the current version of SpaceWire-RT standard and consequently produce the new version of the specification.
Satellite onboard control systems have changed significantly towards of complexity of control algorithms. Network operation must be flexible and adapt easily to configuration and composition changes of the onboard network. Plug- and-Play should solve this problem. Plug-and-Play technology is aimed for network monitoring, should promptly detect changes in it and correctly handle any network situation. Due to size increase of onboard networks, one center (Plug-and-Play Manager), which would quickly react to changes in the entire network, is not enough, one must have several such centers. Thereby there is the problem of Plug-and-Play manager's placement in the network, to provide rapid response and efficient management of other devices in the network. Depending on the SpaceWire network functions and requirements, it must be taken into account in its design, in determining position for the Plug-and- Play managers. In the paper, we consider some reference variants of SpaceWire/GigaSpaceWire networks: ; Network designer chooses the number of Plug-and-Play managers according to the network size and others parameters. The network is not clustered, not divided into subnetworks. : Network designer chooses the number of Plug-and-Play managers according to the network size and others parameters. However, the network that is initially undivided into subnets, in the search for of the network managers location is divided into subnets. : Network designer clusters the network, divides it into subnets. For each subnet, the manager's placement problem is solved separately in accordance with the requirements to particular subnet. In this paper, we will consider in details two approaches to determining location of Plug-and-Play centers in SpaceWire/GigaSpaceWire networks. The first approach is based on a method of graph partitioning into subgraphs. The second approach is based on a P-median graph search algorithm. Both approaches are described in details. Advantages and disadvantages of these methods will be presented; their computational complexity will be evaluated. In network managers placement it is important, what will be characteristics of data transfer from Plug-and-Play managers to nodes. These characteristics include data transmission time, data transmission delay, etc. It is important how the network nodes are distributed among the Plug-and-Play managers for control. The network managers loading should be as uniform as possible. All these parameters directly affect the quality of the Plug-and-Play technology. We assess transmission characteristics between the Plug-and-Play manager and network nodes for each of these approaches, give recommendations of using these approaches for Plug- and-Play managers placement, taking into account various features of the construction and administration of SpaceWire/GigaSpaceWire networks.
The paper presents a study of efficiency of information embedding in BMP images by using codes perfect in a weighted Hamming metric (WHM) and standard Hamming codes. The weighted container model and modification of algorithm F5 is used, which allows to record information in multiple bit planes images (MLSB), taking into account the significance of each bit plane. In this paper the effectiveness of such weighted embedding approach is compared with the common matrix information embedding method that uses classic Hamming code (7,4,3). The effectiveness of information embedding is estimated by PSNR metric and by special Penalty function value. Also composition of RGB color channels in different order is attempted to define the best weighted container structure taking into account Human Vision System features.
High-speed onboard networks for the space industry with a lot of tasks that could be solved only by transmitting large data streams in a short time, with minimum overheads and accepted latencies. Particular tasks for data transmission require various types of traffic and onboard network topologies. Video data in many applications generate high throughput real-time data streams, from most demanding onboard traffic. The SpaceFibre protocol, which gives an ability to transmit data with high speeds and different quality of services (QoS), could be prospective technology for the spacecraft tasks and missions. Implementation of SpaceFibre and considering its application for Russian space missions is going on. The paper presents use cases for SpaceFibre based onboard networks for real-time video data streams in prospective missions. We consider features and characteristics of raw, non- compressed video data streams for processing and real-time control (e.g. to support docking), data streams of compressed motion imagery to record video, science experiment high quality video, robotics, high definition television frames to monitors, etc. The paper considers requirements and restrictions for building SpaceFibre onboard networks for real-time video data streams. Streaming Data Transport Protocol is mapped on a SpaceFibre network for transmission of streaming data from onboard cameras (video stream), to onboard monitors and to a high rate downlink.

Today, mixed-criticality systems are increasingly being implemented on multicore platforms. So, one of the most actual and important problem in the field of mixed-criticality system is a scheduling tasks with different criticality levels on multiprocessors. In this paper, we will describe the main features of mixed-criticality systems. These include basic methods of its organization and main issues of mixed- criticality scheduling for multicore platforms. Moreover, we will report kinds of multiprocessors, types of multiprocessor scheduling, standards, concepts and research projects, related to mixed-criticality systems. At last, we will detail and compare several mixed-criticality scheduling approaches for multiprocessors.
In solving various kinds of problems detect and determine elevation of coordinates of air targets requires modelling of the underlying surface for breeding secondarily emitted from the target of the probing signal.

The paper describes two mechanisms which solve the problem of time multiplexing for SpaceWire networks. They are a transport-level scheduling mechanism, which is used in the STP-ISS protocol, and SpaceWire-DSUAI, that is a protocol prototype. The current paper presents an overview of these mechanisms and compares them. In addition, we provide a short analysis of time-division multiplexing in the communication protocols.
