陸上移動体衛星通信における航行衛星信号遮蔽データの活用方法を提案する。本手法を用いると、L1 C/A 1.5GHzの航行衛星信号受信機を用いるだけで、魚眼レンズ撮像に相応する遮蔽データを効率的に採取できる。本方法によって構築されたデータは近い将来の陸上移動体衛星通信社会において、重要な役割を果たすことを指摘する。 |

A novel scheme is proposed and demonstrated where satellite visibility viewed from running vehicle is economically and effectively evaluated with such low cost GPS receivers like equipped in automobiles. Our preliminary experiment articulated even economical L1 C/A 1.5GHz GPS receivers can create enough precise database of ground feature blockage, compared to fisheye photograph method, if only two statistical parameters we propose are adequately set. Integrating the series of our efforts on this research field, we concluded it is feasible to make an automatic database creation system by the cooperation of government and civil with low cost GPS receivers. Besides, we discussed that the database was very useful in near future's Land Vehicle Satellite Communication society. |
