Why GNSS antennas are essential for accurate positioning

From navigation apps and farming equipment to autonomous vehicles and surveying tools, global navigation satellite system (GNSS) technology empowers many aspects of our daily lives. A GNSS antenna is the core of every system using a satellite-based global navigation system. GNSS antennas are designed to receive signals from satellite constellations, including GPS, GLONASS, Galileo, and BeiDou. These signals provide accurate location and time information, whatever the weather, everywhere on or near the Earth, as long as there is an unobstructed line of sight to four or more GPS satellites. Designing the antenna system to ensure optimal accuracy and reliability of that data is central. A well-designed GNSS antenna that is structured to guarantee robust signal reception, even in severe conditions, such as urban canyoning conditions and forest or mountainous terrain. Deluxe antennas, in addition to excellent elements, can also feature filters to destroy multiple signals and hence interfere...

Enhancing accuracy with next-generation satellite reception

Both navigation and surveying depend hugely on satellite navigation, as does precision agriculture among other technologies, these days. Fancy receivers and correction services tend to steal the show, but your GNSS antenna is just as important for the performance of your system. Since GNSS antennas are the first component to receive the satellite signal, they have an important effect on the positioning data quality. An optimal GNSS based antenna is expected to receive signals of various constellations, such as GPS, GLONASS, Galileo, etc.  while suffering negligible attenuation. Similar (but opposite) could be said for GNSS antennas that are not of the highest quality however are produced to minimize multipath (reflected signals), have as high as possible values of the phase center all along the antenna (extremely important in high precision applications like RTK positioning or geodetic survey at that. And any GNSS receiver, no matter how high-end, can't provide the correct data wit...
