Low Cost Radiation Hardened Software and Hardware Implementation for CubeSats

Expecting the Unexpected - Radiation Hardened Software

Radiation induced Single Event Effects (SEEs) are a serious problem for spacecraft flight software, potentially leading to a complete loss of mission. Conventional risk mitigation has been focused on hardware, leading to slow, expensive and outdated on-board computing devices, increased power consumption and launch mass. Our approach is to look at SEEs from a software perspective, and to explic...

Low cost and highly reliable radiation hardened latch design in 65 nm

Low cost and highly reliable radiation hardened latch design in 65 nm CMOS technology

As a consequence of technology scaling down, gate capacitances and stored charge in sensitive nodes are decreasing rapidly, which makes CMOS circuits more vulnerable to radiation induced soft errors. In this paper, a low cost and highly reliable radiation hardened latch is proposed using 65 nm CMOS commercial technology. The proposed latch can fully tolerate the single event upset (SEU) when pa...

KMote - Design and Implementation of a Low Cost, Low Power Hardware Platform for Wireless Sensor Networks

Wireless Sensor Networks (WSNs), as the name suggests consist of a network of wireless nodes that have the capability to sense a parameter of interest like temperature, humidity, vibration etc. The sensed parameter is often relayed to a base station through the network formed amongst these nodes. The devices used are typically characterized by low cost, low power and are rugged in operation. Th...

Fabrication of low cost in-house slab homogeneous and heterogeneous phantoms for lung radiation treatment

Background: The heterogeneous composition of the human body presents numerous tissue types and cavities with widely differing radiologic properties. The aim of the present work was to develop a low cost homogeneous and heterogeneous phantom and the absorbed dose were measured by ionization chamber for different radiotherapy treatment techniques and compared with treatment planning syst...
