One of the problems with the base station equipment is that there is a large difference between the replacement time of the hardware equipment such as the base station equipment and the radio access equipment, and the evolution period of the communication standard. Therefore, the base station communication platform must be flexible enough to handle the evolving communication standards after purchase. Recent research on reconfigurable communications platforms has focused on the efficient architecture of the communications platform to meet these requirements through software downloads while still using existing hardware. This paper presents a prototype of a base station communications platform based on the ETSI standard reconfigurable architecture. The communication platform presented in this paper is implemented as an ETSI standard reconfigurable architecture using a general-purpose DSP (Digital Signal Processor). In the implemented prototype, we verify the real-time feasibility of communication protocol updates through software reconfiguration.

It develops in the development efforts about the terminal software platform while the telematics service is activated. Domestically, a standard is developed around the Korea Telematics Standardization Forum. And it is taken in reviews for the WIPI which is supporting the telematics. Internationally, it develops standards for the vehicle based platform in the standardization organizations like OSGi and GST. Under this background, this paper tries to propose the terminal software platform standard in which the vehicle information based telematics service can be taken. For this, firstly domestic and international telematics standard conditions are looked into around the terminal software platform. The terminal software platform standard proposed in this paper is illustrated in the architecture, the required function and the interface side.

This study proposes development of 3U CubeSat standard platform whose function and performance are verified via KAUSAT-5 development. 3U CubeSat platform specification was selected for the design of 3U Cubesat standard platform by examining existing CubeSat and state-of-art technology, and consequently a universally usable 3U CubeSat platform was designed. Standard platform was manufactured in 1.5U size and developed with a modular concept to be able to add and expand payloads and ADCS actuators for meeting the user's needs. In addition, in case of the power system, the solar panel, the battery, and the deployment mechanism are designed to be configured by the user. In the mechanical system design of a standard platform, subsystem and micro equipment functions/performance could be integrated and miniaturized on micro-sized PCBs and maximized electrical capability to accommodate multiple payloads. In the development of the 3U CubeSat, the satellite platform adopts the developed standard platform, which can reduce the cost and schedule for the whole satellite development by reducing the additional function verification.

As communication technology, an enabling technology for ITS, becomes diversified with DSRC, CDMA, Wireless LAN, it is expected that type and function of ITS services will become gradually expanded. As a result, research and development of a standard platform that can provide support so that numerous communication technologies that are being used in various ITS services to receive various ITS services can be operated in one integrated terminal are being carried out. On Board Unit (OBU) for a recent standard platform was also built and tested recently. However, verification for standard suitability of the standard platform OBU that was developed must be carried out. Standard technology must be realized and sufficient functional and operational testing must be carried out in order to guarantee efficient operation in an actual ITS system and increase utilization of standard technology. Therefore, In this paper we had constructed test road and we had tested a standard platform OBU for a standard application.

Unmanned Aerial Vehicles (i.e., drone) are gaining a lot of interest from a wide range of application domains such as infrastructure monitoring and parcel delivery service. In those service scenarios, multiple UAVs are involved and should be reliably operated by so-called UAV management system. For that, we propose oneM2M standard based UAV management and control system which is specifically targeted at traffic management of low-altitude UAVs. In this paper, we include oneM2M platform architecture and its implementation for UAV management system in conjunction with UAV interworking procedure.

For avoiding the waste of costs for building each mobile platform according to each mobile communication vender, KWISF proposed WIPI platform standard. Already the venders are providing mobile map services which are adapted on their own platforms. Because the integration of various mobile platform was performed to WIPI standard, the changes of platform and component API may cause the environment changes of mobile nap services. This study shows the design and implementation results of mobile map services adapted to WPI environments.

Purpose: The purpose of this study is to evaluate durability of platform safety step system in railway. Method: We performed finite element analysis & durability analysis of platform safety step system with VPD (Virtual Product Development) techniques and examined the durability standard & qualification life through the rig test during no failure test time in reliability qualification test. We continued to test 1 million cycles in KRS (Korea Railway Standard) for system's robust design performance. Result: FEM analysis results are 14.9MPa & 14.7MPa of pin-joint, pivot and durability analysis result is above 1 million cycles. we calculated theoretically no failure test time 855,000 cycles and through the 1 million cycles durability rig test in KRS standard we confirmed product quality. Conclusion: This platform safety step system was designed very safe in terms of a mechanical strength & durability.

In this paper, we propose a development method of portable Automatic Test Equipment based on PXIe platform. Legacy VME form factor structured test equipment has limited reuse and expansion of modules due to unapplied bus specification. In particular, these limitations can cause development periods and costs to increase, and the reliability of environmental conditions is lacking due to non-standard modules. The test equipment of the proposed PXIe platform can use diverse COTS modules to shorten the development period and minimize the instability between developments. The PXIe development module works with standard Xilinx FPGAs, PXIe Windows device drivers, and applications on standard PXIe buses. The use of standard bus and COTS modules increases scalability and reusability, enabling rapid development and excellent maintenance. Through the test, we show the proposed test equipments can be implemented efficiently between the development processes and proved their reliability through function tests and environmental tests.
