Design of serial communication system between FPGA and GPS-OEM Board [Date:] Source: Electronic Components application Author: Chen shilei, Liu Guixi, to Guohua [Font:Large Medium Small] 　 0 Introduction Global Positioning System (GPS) is the second generation of satellite navigation system in the United States. It is developed on the basis of the satellite navigation system of the Mer

LBS has been widely used in mobile devices and browsers. Based on APIs, it can easily implement address location-related applications, however, I still don't know how to obtain the user's location information behind these Apis. Today I spent some time studying it: There are two ways to obtain location information: GPS and Wi-Fi. 1.GPS The basic principle of GPS is to measure the distance between the satellite at a known position and the receiver of th

I used to look forward to the Chinese version of Google Maps in "Application Development and Analysis of Google Maps ".The birth of APIS is expected to create Google map applications for thousands of third-party websites. Today, I accidentally discovered that the Chinese map API has already appeared. In fact, unfortunately, today I found that a Google Maps satellite map application developed by myself cannot display

Someone asked me the day before yesterday. I don't know yet. I saw it on the Forum and added it to my favorites. Haha Scale and resolution of Remote Sensing Images The image resolution rate is an important indicator for determining the image accuracy. The image accuracy must meet the image recognition capability and accuracy requirements of the corresponding scale map update, and the map update cost must also be taken into account. Redundant resolutions increase the cost of purchasing weixing im

In the previous article, "Introduction to various wireless WLAN Access Technologies", we introduced the overview of wireless WLAN Access Technologies and six Wireless Access Technologies, below we will complete up other types of wireless WLAN access technology. We are familiar with these technologies. 6. Wireless WLAN Access Technology-DBS satellite access technology DBS is also called the digital live broadcasting
