The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage of observing the solar activities and its effect on space weather in real time. The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors. Using the special vantage point L1, four payloads directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium

It consists of Lander and Rover configuration. It will be launched by LVM3 from SDSC SHAR, Sriharikota. The propulsion module will carry the Lander and rover configuration till 100 km lunar orbit. The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit.

The cellular market is moving from 3G to LTE, LTE Advanced and LTE Advanced Pro to improve data rates and reduce power, all the while looking to the next generation 5G technologies. This will bring many more frequency bands at higher frequencies for even higher data rates. This will also bring in other technologies currently used in unlicensed frequency bands such as Wi-Fi. At the same time, operators and developers are looking at advances to cellular wireless to provide low cost, reliable and scalable wireless links for the Internet of Things (IoT). For these applications it is power consumption and battery life that is the driving factor, and narrow band solutions are now emerging. Alongside these are the latest evolutions to specifications such as Bluetooth and ZigBee that are also targeting IoT applications. Bluetooth 5 promises greater range and data rates with lower power, while ZigBee 3.0 brings lower power to the mesh networks. All of this can give the design engineer a major headache. The choice of wireless protocol for low cost, low power, global applications can be complex and not particularly stable.

Their operation will directly determine the reliability and efficiency of the product. To enhance the performance of the switching circuit of power converters, snubbers are placed across the power switches to suppress voltage spikes and damp the ringing caused by circuit inductance when a switch opens. Proper design of the snubber can result in higher reliability, higher efficiency and lower EMI. Among many different kinds of snubbers, the resistor-capacitor (RC) snubber is the most popular snubber circuit. This article explains why a snubber is needed for power switches. Some practical tips for an optimum snubber design are provided as well. Figure 1: Four basic power switching circuits.

To support this automation, a wide variety of sensors is required. The focus of this article will be on home and office applications that are required to know when a person enters, leaves, or is just present in a room or area. Occupancy sensing around the home or office offers many conveniences ranging from turning lighting on or off as people enter and leave an area, controlling the HVAC system based upon where people are present, and property security systems which can sense activity when there isn't supposed to be any. Many systems that support these kinds of applications use passive infrared (PIR) sensors. PIR sensors have been commonly used in building automation and security systems for occupancy and object detection. They even work well when it comes to sensing motion of objects or people. However, more advanced detection applications have requirements that PIR sensors are unable to satisfy given their limitations.
