The safety of GPS is not a new topic.
The most famous example would be the 2011-Year-old Iranian hijacking of American drones [1]. December 4, 2011, the United States, a RQ-170 unmanned aircraft, flying in Iranian airspace. Instead of shooting it down, the Iranian military used some sort of GPs deception to make the plane land in Kashmar, north-eastern Iran. The intact drone provides the Iranian military with an excellent specimen of research and technology and military secrets.
to provide a business into a number of services areas, with base stations in each section, and base station equipment that communicates with the client side of the site via point to multicast wireless links. Each service area covers a few kilometres to more than 10 kilometres and can overlap each other.Because LMDS has the characteristics of higher bandwidth and bidirectional data transmission, it can provide many kinds of broadband interactive data and multimedia service, overcome the bottlene

relatively large. After being changed to the system interface, it is much more stable, and the user also reports that the recorded track is much more accurate. There is also the positioning sdk currently used by Baidu map, and the returned data does not have altitude data. This is also one reason that Baidu gps is not used for positioning.
When the base station locates, it feels that Baidu returns faster and faster than AMAP data. The address resolution or search is the same. I don't know if Ba
When I wrote this article, I thought of a poem: no intention of inserting Liu into the shade. Although I used to know the usefulness of the MKT parameter, it was used to display different language versions, but I never thought of adding this parameter to the Bing map API development and expected results.
Many of my friends asked me how to display a satellite map on the Bing map. Because the Chinese Bing map does not support

RSVP protocols are adopted. The video conferencing system used in ADSL, Fttb+lan and other broadband IP networks has achieved good results.
In the IP network ubiquitous today, this way networking convenience, cheap. However, because the packet-switched IP network follows the principle of making the best effort to deliver, the video conferencing effect of this access mode is inferior to that of ISDN, DDN and so on. But its good price-performance has been more and more users of the favor, especi

Red path
A red path is a key task that a user wants to accomplish with a product. Most systems have only a small number of red paths, some of the key activities that people want to do with the system: This is why people buy this product. However, while you can get most people to start using your product, people won't keep using it unless the red path is well done. If the obstacles on the red path cannot be cleared away, persuading users to continue using the system will becom
Example 2. Collecting satellite readingsAs shown in Example 1, the sequence allows unique values to be generated across multiple tables. Sequences also allow for the automatic generation of their values for multiple columns in a table.For this example, consider a orbiting satellite orbiting a planet or moon. This particular satellite SAT1 is designed to capture
, it becomes a real-time monitoring system.③ Real-time system tasks implemented through real-time design. When the system has real-time requirements and the system can meet real-time requirements, the system design is successful. However, when the system cannot meet real-time requirements, we often give up on it. For example, when a satellite is launched, the satellite operation monitoring system that displ

The ground terminal, in fact, is our popular GPS, it can receive your head of those flying satellite signals, and then based on the signal to calculate your current position. Common terminal has car navigation GPS, mobile phone built-in GPS and hiking outdoor GPs and so on. The accuracy of the general civil class is about 10 meters. When using GPS, it is necessary to be able to receive GPS
