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 without also having a consistent phase center.

At the present time GNSS antennas can be realised with a multi-frequency configuration where L1, L2 and L5 bands are all considered. This multi-band receiving method can improve the accuracy of positioning, and the re-appearance of the function of the convergence rate, delay ionosphere influence, and the impact of a single frequency, and suppression of the effect time of more effectively. On tractor for precision farming or on drone for aerial mapping, multi-frequency GNSS antennas are performing better and with better reliability.

Fidelity is just as important as accuracy. The GNSS antenna is also perhaps one of the most important components of a wireless sensor; the antenna should be durable enough to all environmental conditions that are scorching hot to freezing cold, moist to a dry, etc. and even moisture, dust and vibrations also. They need to be tough and reliable, and that’s the best way to describe the cutting-edge GNSS antennae that sell.

Finally, to make the most of your positioning system is to purchase quality GNSS antennas. You expect your GNSS antennas to do what you demand of them every single day: provide a stable, strong and interference-resistant signal that you can rely on to ensure your data is the most accurate, consistent and reliable it can be – no matter what you are trying to do with it.
