These days, when it comes to GPS devices the antenna is typically part of the package. But what better opportunity for [Pepijn] to learn how to make a GPS antenna from scratch for a badge add-on? A ...

Pasternack’ s new GPS/GLNSS antennas provide precise reception of satellite timing signals and reference frequencies for use in advanced mobile and base station network applications. These IP67-rated ...

THE ANTENNA. This crucial component of any radio transmitting or receiving system has a history that actually predates the invention of radio itself. The first antennas were used by Princeton ...

GPS position determination systems operate by measuring the signals propagated from synchronised clocks carried on a constellation of (currently 30) satellites in earth orbit at a height of 20,200 km.

Fig 1. A typical GPS receiver includes several key components, including the RF input, the LNA, a SAW filter, a TCXO, and the GPS RF chip. Fig 2. The key components of the GPS receiver should go under ...

Anyone who has tried to use GPS in downtown Los Angeles knows that the indicated GPS location can vary greatly from the actual location. This is caused by GPS satellite signals bouncing off city ...

Modern GPS receivers are extremely sensitive signal detection devices. With tracking sensitivity’s below -160dbm, they can detect signals at 50dB below the ambient thermal noise in the channel.However ...

Laptop manufacturers constantly seek to shave any inch or ounce off their notebooks to make them more convenient -- and attractive -- to potential buyers. So a recent development in antenna design ...

GPS is really fun to play with in your projects. But when [Trax] decided to build a GPS chip into his design the fun ended abruptly. Above you can see the section of the board devoted to the hardware.
