Recently, real time information on the local ionospheric condition is becoming an important need for space and ground based technological systems which are prone to be affected by the local ionospheric state. Knowledge on the impact from the sun activity to the equatorial and low latitude ionosphere is crucial for research and development purpose in all developing nations which are relying on space-based technology systems such as the Global Navigation Satellite System (GNSS). As the first action step to achieve deeper understanding and hands on experience on real time ionospheric monitoring, the National Space Agency of Malaysia (ANGKASA) in collaboration with Universiti Teknologi Malaysia (UTM) has developed the first near real time ionospheric and space weather monitoring system for Malaysia (My-Iono) in year 2015. This web-based platform operates based on the National R&D GPS Continuously operating reference station network (NRC-net). The system runs based on a locally derived algorithm called Equatorial Ionosphere Index (EIX). The EIX was formulated based on 10 years (2004 to 2013) GPS derived empirical Total Electron Content (TEC) data obtained frpm 78 My-RTKnet stations around Malaysia. The fundamental of My-Iono Service consists of vertical TEC maps with a latency of ∼ 2 mins over Malaysia and information on the current ionospheric status; Normal, Medium and Severe, time series of Mean VTEC for station specific, time series of RAte of Change of tEc (RACE) for station specific and time series of Ionospheric Zenith (Iz) Delay for station specific estimated in near real time using GPS observations. This paper presents on the development of My-Iono Service in terms of system design and architecture.
