Observation of equatorial ionospheric plasma bubbles at peninsular Malaysia

The research on observation of equatorial plasma bubbles (EPBs) ionospheric at peninsular Malaysia by using Malaysian Real Time Kinematic Global Positioning System Network (MyRTKnet). Plasma bubbles which usually occur during midnight. This determination is made for satellites in Peninsular Malaysia in the September period of 2007 at Universiti Utara Malaysia (UUMK) and Sungai Petani (SGPT). The important parameter in this project is Total Electron Content (TEC) which is the value of TEC change rate; ΔTEC is taken within the period of every 15 seconds in order to detect Plasma Bubble. TEC is extracted using GPS receiver which in RINEX format that supplied by JUPEM (Department Of Survey and Mapping Malaysia). The value of ΔTEC is compared base on the dropness of TEC value within the scale. It is shown that most equatorial plasma-bubble events commence at 18:00 UT on 6^th September 2007 for PRN 26, and may last for less than 60 min.
