If it were an essential part of the GPS concept that all users needed to carry a synchronized clock, a smaller number of satellites could be deployed, but the cost and complexity of the user equipment would increase. 参考译文:有时会错误地说用户位置位于三个球体的交点处。虽然这种说法更容易...
Global Positioning SystemGPS locationlivestock distributionGlobal Positioning System (GPS) tracking devices are a fundamental technology for quantifying the distribution and movement of livestock across landscapes. Although costs of GPS devices have decreased, it is still cost prohibitive to implement a ...
Developed by the United States Department of Defense, it is officially named NAVSTAR GPS (Navigation Signal Timing and Ranging Global Positioning System). The satellite constellation is managed by the United States Air Force 50th Space Wing. Although the cost of maintaining the system is ...
The NAVSTAR global positioning system (GPS) is the successor to the Navy navigation satellite system (NAVSAT) (see Doppler Positioning: Satellite ). It was developed to provide instantaneous, global, three-dimensional position and velocity for navigation to an accuracy higher than that possible with...
Global Positioning System (GPS) collars have proven to be an efficient tool for studying wildlife. However, this technique generally requires great investment in material, which notwithstanding its possible cost-effectiveness, is still beyond the means of most of the scientific community in developing ...
Synchronization to GPS time (or UTC) can be achieved to < 0.1 μs using a relatively low-cost receiver. This method is suitable for many time-tagging applications, such as in seismology, SLR, and even for GPS receivers themselves. That is, by using on-board point positioning software, ...
