2. Not using 10 MHz of bandwidth closest to the GPS bands, and accelerating plans to use an additional 10 MHz further away, originally intended for service expansion in the future. LightSquared claims that 99.5% of GPS receivers would be free of interference from their transmissions. ...
Because the global positioning system (GPS) consumes a lot of power and does not work indoors, many GPS-free information brokerage schemes have been proposed for wireless sensor networks. In most existing schemes, the unit disk graph (UDG) model is used as the communication model. However, in...
In particular, there’s a free PDF download of “GPS: The First Global Navigation System”, a book from Trimble that may be the best basic introduction to how GPS works that I’ve seen, and how it’s used; a bit technical in spots, but not overwhelmingly so....
由于受到地形和特殊应用的限制,GPS在很多情况下不适用于自组网的定位.本文提出了一个自组网中GPS-Free的三维定位系统ANGEPS,并阐述其系统结构和其中的条件泛洪全局定位方法———露珠泛洪法.在给定的物理模型下,提出了露珠泛洪法的工作过程和代价估算,并在数学上加以了描述和证明,给出了系统性能最优的条件.关键词...
A GPS-free localization scheme for wireless sensor networks is presented in this paper. First, we develop a standardized clustering-based approach for the local coordinate system formation wherein a multiplication factor is introduced to regulate the number of master and slave nodes and the degree ...

EasyGPS is the fast and easy way to upload and download waypoints, routes, and tracks between your Windows computer and your Garmin, Magellan, or Lowrance GPS. Use EasyGPS to back up and organize your GPS data, print maps, or load new waypoints onto your GPS for your next hike or geoca...
A few consumer-grade GPS receivers will show you the current DOP; more advanced commercial models can show you a predicted plot of DOP over the course of the day, useful in figuring out the best time to get an accurate position measurement. I’veposted previously about the free Trimble Plan...
Secure and Energy-Efficient Geocasting Protocol for GPS-Free Hierarchical Wireless Sensor Networks with Obstacles Wireless sensor networks (WSN) are nowadays a very promising field and are used in various types of applications requiring advanced and low-cost geocasting... BN Paho,VK Tchendji - 《...
