Summary:
A new scheme is proposed and demonstrated where satellite visibility viewed from running vehicle is economically and effectively evaluated with such low cost GPS receivers like automobiles are equipped with. Our preliminary experiment articulated even economical L1 C/A GPS receivers can create enough precise database of ground feature blockage if only two statistical parameters we propose are adequately set. The geographical characteristics of satellite visibility are demonstrated in this scheme. A blockage database will be created in the cooperation with the government and the civil in the style of a low-cost and large-scale automatic survey. The blockage database will be cost-effective and useful in future’s vehicular satellite communications, as it allows predicting the linkage block and achieving an adequate handover, only based on the economical database which is simply created by gathering the signal data not having contributed to the positioning the prevailing L1-band C/A GPS receivers.
