Control analysis of acquirement and locking in inter-satellite laser communications
SPIE Proceedings, 2011Process of acquirement and locking-up of compound axis system in inter-satellite laser communication has been studied. The effect of different condition parameters on the process of acquirement and locking-up have also been researched and simulated. Simulation results show that when the system with appropriate bandwidth has been adopted, both fine ...

Fiber Bragg grating as optical filter in laser inter-satellites communication
SPIE Proceedings, 2007This paper proposes a method of using fiber Bragg grating as optical filter in laser inter-satellites communication system. Effects of Doppler shift to SNR and band requirement of optical filter are researched in this paper. Given the wavelength is 1550nm, strong fiber and Blackman windows function are used in designing fiber grating to satisfy the ...

Inter-satellite laser communication system based on double Risley prisms beam steering
Applied Optics, 2019We designed an intensity modulation direct detection free-space laser communication terminal. In this system, the output power of the signal-modulated semiconductor laser amplified by two-stage fiber amplifier is 2 W, and the modulation contrast is 15 dB. Tracking of the incident beam and demodulation of the communication signal are realized by using a

Satellite trajectory simulator for inter-satellite laser communication system APT test
SPIE Proceedings, 2006The characteristics of the terminals for the inter-satellite laser communication must be tested and verified on ground before flight test. A pair of terminals for inter-satellite laser communications was developed for principle demonstration. A terminal has two main subsystems.

Wave-front distortion and its effect on inter-satellite laser communication systems
2010 Academic Symposium on Optoelectronics and Microelectronics Technology and 10th Chinese-Russian Symposium on Laser Physics and Laser TechnologyOptoelectronics Technology (ASOT), 2010Wavelet model is built to depict the diversified wave-front distortion. Compared to Gaussian model, the effect on pointing error is analyzed. For it is difficult to detect the wave-front distortion to the receiver, especially for long distance, a near field center power measurement method is proposed.
