Experimental Study of External Interference for Weak Spike Noise Observed with Satellite AIS
Daichi Hirahara (JAXA) SAT2019-50
Abstract (in Japanese) (See Japanese page) 
(in English) The Japan Aerospace Exploration Agency (JAXA) launched a second space-based Automatic Identification System (AIS), SPace based AIS Experiment 2nd (SPAISE2), mounted on DAICHI-2 in 2014. SPAISE2 was moved to an extended operations phase in May 2015, and is now continuously observing the sea around Japan to evaluate external interference and signal collision. This study reports separating for AIS messages and the external interference of weak spike noise. This paper cites the example of a case where the threshold for separation is dynamically adjusted.
