A "GNSS compass" uses a pair of antennas separated by about 50 cm to detect the phase difference in the carrier signal from a particular GNSS satellite. [8] Given the positions of the satellite, the position of the antenna, and the phase difference, the orientation of the two antennas can be computed.
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
Nav finder and underwater compass – basic underwater navigation tools Suunto SK-7 diving compass in aftermarket wrist mount with bungee straps. Diver navigation, termed "underwater navigation" by scuba divers, [1] is a set of techniques—including observing natural features, the use of a compass, and surface observations—that divers use to navigate underwater.
There are several methods to create a Geotagged photograph (see also Geotagging).The application of this is to allow photo management applications to use this information to manage images.
Compass-M1 is an experimental satellite launched for signal testing and validation and for the frequency filing on 14 April 2007. The role of Compass-M1 for Compass is similar to the role of the GIOVE satellites for the Galileo system. The orbit of Compass-M1 is nearly circular, has an altitude of 21,150 km and an inclination of 55.5°.
The Army helicopter that collided with a passenger jet last week in Washington had its tracking technology turned off at the time of the crash, U.S. Senator Ted Cruz told the New York Times. The ...
Septentrio’s receivers were used to track experimental Galileo signals transmitted by the GIOVE-A satellite and were also the first to track the signals of the first experimental satellite of the future Chinese Compass navigation system. In the line of user products the company keeps its focus on multi-system receivers that make use of all ...
Pelorus aboard HMS Belfast. In marine navigation, a pelorus is a reference tool for maintaining bearing of a vessel at sea. It is a "simplified compass" without a directive element, suitably mounted and provided with vanes to permit observation of relative bearings.
