An Improved Satellite Selection Method in Attitude Determination Using Global Positioning System (GPS)
نویسندگان
چکیده
In attitude determination using GPS, the accuracy of results is influenced directly by the satellite selection of the differenced observations. Based on the information of satellites, such as elevation, azimuth and signal to noise ratio, we apply a weighted selection method to obtain the satellite combination used in attitude determination. This method also considered the quality of satellite signal during building double difference observation equations. Experimental results show that this method reduces the noise influence of the double difference carrier phase measurements and increases the accuracy of the attitude determination. Compared to the traditional method, this is more suitable for the attitude determination.

Celestial positioning has been used for navigation purposes for many years. Stars as the extra-terrestrial benchmarks provide unique opportunity in absolute point positioning. However, astronomical field data acquisition and data processing of the collected data is very time-consuming. The advent of the Global Positioning System (GPS) nearly made the celestial positioning system obsolete. The n...

Global positioning system (GPS) technology is well suited for attitude determination. However, in land vehicle application, low-cost single frequency GPS receivers which have low measurement quality are often used, and external factors such as multipath and low satellite visibility in the densely built-up urban environment further degrade the quality of the GPS measurements. Due to the low-qual...

Measurements of the dual frequency Global Positioning System (GPS) receivers can be used to calculate the electron density and the total electron content (TEC) of the ionosphere layer of the Earth atmosphere. TEC is a key parameter for investigating the ongoing spatial and temporal physical process of the ionosphere. For accurate estimation of TEC from GPS measurements, GPS satellites and GPS r...
متن کاملAttitude Sensing Using a Global-positioning-system Antenna on a Turntable
A new attitude sensor is proposed that consists of a single global positioning system (GPS) antenna mounted on a turntable with its phase center offset from the turntable's spin axis. It is being considered as a means of sensing 3-axis attitude information. It is attractive because its GPS receiver could have a low number of channels and, therefore, be smaller and use less power. The system sen...

The Unmanned Aerial Vehicles (UAV) positioning in the outdoor environment is usually done by the Global Positioning System (GPS). Due to the low power of the GPS signal at the earth surface, its performance disrupted in the contaminated environments with the jamming attacks. The UAV positioning and its accuracy using GPS will be degraded in the jamming attacks. A positioning error about tens of...
