Design and Development of NavIC and GPS based Geolocation System for CO2 Monitoring

With the development and implementation of NavIC, India has joined the league of very few countries having its own satellite navigation system. NavIC when used together with GPS, provides improved positioning accuracy. Therefore, the design and development of indigenous $\text{NavIC} +\text{GPS}$ based geolocation systems for mobiles, automotive, IoT services, tracking and monitoring systems, etc. have been gaining significance. In this paper, a $\text{NavIC}+\text{GPS}$ based geolocation system for CO2level monitoring is designed using a low-cost $\text{NavIC}+\text{GAGAN}/$ GPS receiver module, Microcontrollers, and a CO2Sensor. This system measures the CO2level with respect to $\text{NavIC} + \text{GPS}$-based location and time. The proposed system is economical and is a step towards the adoption of NavIC in monitoring systems. Also, such systems carry significance in view of the increasing air pollution in major Indian cities. Further, this system can be extended to monitor major air pollutants such as PM10, PM2.5, dust etc.
