Third Ventricle and Suprasellar Cisternsilitary applications. The GPS system, GLONASS system and Beidou system are all enhancing their anti-jamming capability by increasing more output power. Besides power amplifier and antenna, the power enhancing technology also calls for new demand to passive devices. High power capability, low loss, m

Third Ventricle and Suprasellar Cisternson the same carrier could be multiplexed into a constant-envelope signal with these techniques. Increasing of signals would deteriorate the crossing correlation and its impact on receiving is analyzed. It is shown that cross correlation between signals in-phase has considerable influence; in contras

For considering the cost and complexity of receivers, only the lower sideband signal may be received for mass ma

Clinical History and Physical Examinationof protostars and the initial stages of star formation. The observation of the radio signal is very sensitive to the interference environment present in the band since the investigated signal is received with a very low power. In this paper, according to the International Telecommunications Union re

Chronic Obstructive Pulmonary Disease in the domestic and foreign literatures of deriving the minimum of GDOP. The existing theories of minimum of GDOP are all based on the observations of ground stations, and the deduced GDOP minimum value cannot be reached because the observable range of the receiver do not be considered. Then, the m

J. P. Lynch III,E. A. Kazeroonit. 0th and 1st order ionospheric correlation function was established for China area, and analyzed for various ionospheric conditions. It is shown that the ionospheric delay difference does not vary linearly with the distance, and the residual ionospheric error after the planar fitting of grid model

Wilfried De Backer,Jan Verhaert unmanned aerial vehicles and airships are needed to obtain the best configuration by analyzing GDOP. Then aiming at the pseudolites’ positioning, a new integrated scheme was proposed, where distance between two aircrafts is utilized to improve the positioning accuracy. Simulation results show that

Yves Sibille,William W. Merrill35. Tracking all available satellites simultaneously leads to unacceptable computation burden for standalone receivers. Most satellite selection methods were therefore proposed to release the computation load with the minimum satellites set to maintain endurable positioning accuracy under the least
