LEO Satellites is Low Earth Orbit typically organized as a satellite constellation. The number of Satellite LEO would be ten to even thousand to fully cover the globe. As LEO satellites move very quickly and are most visible for 20 to 30 min during each pass, it requires an antenna that can track signals, and satellite paths, and upload and download as much data as possible in a short amount of time. The continual motion of tracing one LEO satellite after other equates to significant mechanical performance. So in this paper, we carry out a review of which antenna suites are best for tracking the LEO, getting data from them, and also the mechanical parameter of Antennas.

Controlling different IR devices with their individual remote can prove to be cumbersome. Life would be much easier if there had been a single remote with a user friendly interface to operate all the IR devices. Due to the technological advancement and the need for smart home, we can tremendously reduce our dependence on remotes by making a multi-functional or universal remote that can operate all the IR devices. The paper put forwards an approach to completely remove the use of remote and utilize our android mobile with Bluetooth facility to control the home appliances. This paper stresses on the new technology evolved in the form of PSoC (Programmable System-on-Chip) with BLE (Bluetooth Low Energy) which is used to transmit the infra-red codes based on the protocols on which the devices work..

Progress in this held is based upon understanding and solving number of issues. Radiation experienced by aircraft in the outer space is one of them, where the sun is the main source of radiation. Electronic components on board the aircrafts/spacecraft are exposed to these radiations which can cause reduction in the lifetime of a craft and even mission failure. Phase-locked loops (PLLs) are an integral part of many electronic systems. They are used for a number of applications such as local oscillator (LO) in wireless communication systems, clock recovery circuitry at the serial or parallel high speed data links, synchronizing data transmission and as a frequency synthesizer in digital systems. This report summarizes effects of radiation which is introduced in a phase locked loop circuit in the form of a current pulse.
