NIUSAT is a 15-Kilogram Nanosatellite developed at Noorul Islam University with the objective of creating a new modular small satellite platform for a variety of applications. Carrying a Miniature Wide Field Sensor (MWiFS) and Ocean Color Monitor (MOCM) to capture medium-resolution imagery, NIUSAT will collect a variety of information for agriculture, fishery and disaster relief.

NIUSAT is 35 by 35 by 37 centimeters in size and employs a highly modular design in order to create a new small satellite platform that can be easily integrated with a variety of payloads for application in remote sensing, astronomy and communications.

The primary objective of NIUSAT is the collection of photos for agriculture and disaster management support applications. One particular area of interest to be imaged on every pass is the Kanya Kumari District to study potential agricultural diseases of crops. NIUSAT also provides data for the Disaster Management Support (DMS) project to address disasters due to flood, cyclone, drought, forest fire, landslide and earthquakes. Imagery from the satellite can also be used to locate potential fishing zones around the coasts.

The main objective of PISAT is to develop the capability of designing space systems in a university environment with our students and young faculty. The space systems are to be highly reliable as there is no scope for repair after launch. So, this mission serves as an educational platform for dealing with advanced space technology and its experiments. This is a profound experience for students to build, test, launch, and maintain/ operate our student satellite PISAT.

A custom-made cuboidal structure was evolved to support sufficient power generation and weight optimization. With this structure, a simple spin-stabilized imaging satellite was proposed to ISRO. Later, ISRO suggested a 3-axis stabilized imaging satellite which is the current PISAT configuration.

PISAT is configured with various subsystems namely: Payload, an imaging camera, structure, thermal, communication system, control, actuators and sensors, on-board computers, electrical systems, and mission aspects.
