Abstract Information about satellite antenna phase center offsets (PCOs) is indispensable for high-precision applications of global navigation systems. Pre-flight manufacturer calibrations the PCOs are available all individual Galileo satellites and each frequency. So far, geodetic usage focused on ionosphere-free linear combination E1 E5a signals. In view growing number E5b- E6-capable receive...

AbstractThis paper represents the design of microstrip patch antenna for X-band applications. This antenna can be designed at a single layer single patch four band, E-shape notch and symmetrically H-shape slots loaded compact antenna. The designed antenna can be used for Search and Rescue Radar Transponders (SART) and in Civil, Military Navigation Radars (MNR). The four band antenna is achieved...

This paper deals with the fabrication and characterisation of microstrip patch antenna on a flexible substrate. The flexible planar antenna finds wide applications in defence, satellite, medical and automobile industries. Now days it is the most researched topics across the world. The flexible antenna gets conformal to the surface and can be used across curved surfaces. An antenna using room te...

NAVSYS High Gain Advanced GPS Receiver (HAGR) uses a digital beam-steering antenna array to provide additional gain in the direction of the GPS satellite signals. This increases the received signal/noise ratio on the satellites tracked and also improves the accuracy of the pseudo-range and carrier-phase observations. The directivity of the digital beams created from the antenna array also reduc...
