Satellite-based positioning systems, like GPS, have become omnipresent, guiding us on our car journeys and our treks. They also play a critical role in various applications as diverse as autonomous vehicles, agriculture, and surveying. However, it is important to move from the term “GPS” to ...
Surveying is one of the world's oldest professions. The Egyptians used a system of ropes and knots to relocate boundaries along the Nile after periodic flooding; they also used the plumb bob. The Babylonians are credited with dividing the circle into 360 degrees, and as early as 1600 BCE ...
aThe results show that surveying points position mean error along horizontal direction is ±0.131 mm and vertical direction is ±0.192 mm. Therefore, multi-taking station cross direction digital close-range photogrammetric can completely satisfy the precision need of physical simulation experiment. 结果...

Keep in mind that this discussion and Figures D-13 and D-14 address only the TSI Pointing and Reading error. The total expected angle error would also include the TSI Centering and Target Centering errors which are independent of angle repetition. ...
We outline the motivation of our study below by briefly surveying the background research. Studies aimed at analyzing the market-timing of the portfolio beta—especially in the hedge fund industry—may be divided into two categories: (i) studies that tend to rely on “static” transformations or...
“beacons,” or Wifi™ access points, for geopositioning in areas with limited satellite coverage, the locations of the signal sources must be established prior to geopositioning receivers. Determining locations of signal sources can require land surveying, precise measurements, precise installation, ...
A method and apparatus for operation in a multi-frequency band system in the presence of an interference, the method comprising the steps of: receiving signaling in a plurality of w
Systems and methods of the invention may be used during seismic data collection, including 3-D and 4-D seismic surveying. The inventive systems and methods may also use inline, as well as crossline control to reform a multi-string source shape in real time or near-real time, and/or for ...
During the mineral resource and reserve checking,the surveying data of mining engineering shall be checked. 在矿山资源储量核查中,应对其采矿工程测量资料进行检测。 2. Based on Mizhi-Suide rock salt field analysis,studied hosting characters of rock salt in Jijiamao mining area O2m65 submember in...
