Personal statement

Ir Fitri has more than 15 years of working experience in the electronic and satellite engineering industry. She had participated in the technology transfer program with RazakSAT engineers. She was granted RM3.2m in research funding for development of X-band Satellite Transmitter System and received the completion certificate from MOSTI. She led in the development of CubeSat and InnoSAT communication subsystems. Her primary research interest is in the development of the transmitter system, where she has developed an adaptive transmitter for LEO satellites that optimize the SNR, data throughput and power consumption. She has obtained her PhD from UTM under the same research area.

Research Interests


Research Projects

Title: An Adaptive Front-End UHF Transmitter System for CubeSat Satellite

A transmitter with an adaptive capability to select transmit power and data rate is proposed to improve the CubeSat satellite link effeciency. The adaptive transmitter is providing solution to overcome the variablity of the propagation path. The configuration of the transmitter setting was according to the ground station receiving antenna elevation angle, as per developed in the adaptive transmitter control unit (ATCU). The result of this research proven that the adaptive transmitter can perform its operation in orbit, based on exposure to gamma source and 4 cycle of full thermal-vacuum chamber test conducted.

Title: X band Transmitter System for LEO satellite

Development of the reconfigurable X band transmitter system, which includes reconfigureable modulator, transmitter and antenna. Successfully complete the Engineering Model (EM) for 2D micro-satellite subsystem configuration. Successfully complete the End-to-End test with ground station receiving satellite downlink for remote sensing satellite, with data rate up to 80Mbps (exceed the requirement, only 40Mbps) using multi-phase modulation technique and RF transmit power up to 10W.
