“…Concepts using signatures of the Earth as a virtual beacon source has been discussed in the literature for both the visible and long-wave infra-red regimes. [10][11][12][13] Regardless of the observed wavelength, using the Earth for line of sight vector information has an issue with non-uniformity of the signal and limited signal strength. As a result, signal centroiding will not necessarily coincide with the geometric center of the Earth, limiting the accuracy of the approach.…”

Free space optical communication is of interest to NASA as a complement to existing radio frequency communication methods. The potential for an increase in science data return capability over current radio-frequency communications is the primary objective. Deep space optical communication requires laser beam pointing accuracy on the order of a few microradians. The laser beam pointing approach discussed here operates without the aid of a terrestrial uplink beacon. Precision pointing is obtained from an on-board star tracker in combination with inertial rate sensors and an outgoing beam reference vector. The beaconless optical pointing system presented in this work is the current approach for the Integrated Radio and Optical Communication (iROC) project.

How to measure the pointing angle precisely without the beacon light is crucial for beaconless laser communication. The conventional intensity method directly measures the intensity of a part of the communication signal beam, which has low sensitivity. We propose the characteristic signal method by superimposing a low-frequency sinusoidal signal on the communication signal to promote the measuring sensitivity. Simultaneously, a fast cyclic cross-correlation algorithm is used to reduce operational complexity. Compared with the experimental results of the direct intensity method, the proposed method can improve the measuring sensitivity about 9.17 dB and increase the power budget for communication about 1.96 dB.
