PLANET-B is an ISAS spacecraft which will investigate the upper atmosphere and the surroundings of Mars between 1999 and 2001 To clarify the presence and characteristics of the Martian dust ring/torus, an impact ionization dust detector will be on board PLANET-B The detector (PLANET B Mars Dust Counter), which is an improved version of the Munich D...

Mars Dust Counter (MDC) is a light-weight (730g) impact-ionization dust detector onboard NOZOMI, a Japanese Mars mission, which was launched on July 4th 1998. The main aim of MDC is to detect the predicted Martian dust rings/tori. It can also cover velocitymass ranges of interplanetary and interstellar dust particles. By August 2000, MDC had detect...

The Mars Dust Counter (MDC) is an impact-ionization dust detector on board the Japanese Mars mission NOZOMI, which was launched on 1998-07-04. It is an improved type of MDC-HITEN and MDC-BREMSAT and has three detection channels (electron, iron, and neutral) to discriminate noise signals from impact signals. The main aim of the MDC is to measure dus...

Mars Dust Counter (MDC) on board NOZOMI has detected more than 90 dust impacts in three years. In interplanetary observation from 1999, MDC has detected about 60 interplanetary particles moving around the sun and several interstellar dust particles.

Mars Dust Counter (MDC) is a light-weight impact-ionization dust detector on board Japanese Mars mission NOZOMI, which was launched on July 4th 1998. The main aim of MDC is to detect dust particles around Mars and reveal the distribution of the martian ring or torus of dust from Phobos and Deimos. In three years between July 1998 and June 2001, MDC...

The aim of rapid prototyping real-time applications is to substantially reduce development times by confirming the functional and timely requirements of the application at a very early stage of development with the help of an executable prototype. Hence, the real-time rapid prototyping system presented in this paper integrates two complementary tas...

In order to unveil the presence and characteristics of Martian dust ring/torus, Mars Dust Counter (MDC) is aboard ISAS's spacecraft PLANET-B, which will be launched in 1998 summer and investigate the upper atmosphere and surrounding environment of Mars between 1999 and 2001. MDC PLANET-B is an improved version of impact-ionization dust detectors ab...

Rapid Prototyping has been proposed as a means to re- duce development time and costs of real-time systems. Our approach uses a heterogeneous, tightly coupled multipro- cessor system based on off-the-shelf components as target architecture for an executable prototype, which is gener- atedfrom the specification in an automated design process. Here,...

Locally and functionally distributed applications realized on different system architectures demand a universal, portable and intuitive software utility for interprocess communication. Remote Procedure Calling (RPC) fulfills these requirements but suffers unnecessarily strict synchronization and the danger of deadlocks with complex client/server re...

Rapid Prototyping is used in embedded systems design as a means to reduce development time and costs. At an early stage in the development cycle, the specification is implemented in a working protoype, which can be used to test the specification and, in real-time systems, also the timing constraints. The REAR Rapid Prototyping Environment was built...

Modern microprocessors with caches and pipelines show increasing performance, but at the price of a decreasing predictability of execution times. The design of hard real-- time systems however has to be based on worst case considerations. Consequently, real--time systems are generally oversized and fail to profit of developments in the standard pro...

Embedded hard real--time control systems show growing functional complexity as well as increasing demand for short response times and high computing performance. This paper presents a target system architecture suitable for rapid prototyping embedded real--time applications. The tightly coupled heterogeneous multiprocessor system includes state--of...
