Global Navigation Satellite System (GNSS) technology saw an increase in both the number and quality of use over the last ten years.

Nowadays, technology providers are still working to increase their efficiency. The reliability of geodetic antennas, in addition to dependable receivers, is largely responsible for the caliber of most measured data.

As a result, it's essential that you recognize the numerous possibilities for geodetic antenna applications and, last but not least, the appropriate calibration techniques for the antennas.

1.  Timing

Computation, electrical, and communications system timing and synchronization are now done globally in accordance with GNSS.

Only GPS L1/CA was employed for these applications for quite a while. Yet as modern and innovative GNSS constellations such as Galileo, and BeiDou became accessible, the timing sector began embracing multi-signal, multi-configuration GNSS.

Sophisticated 5G network nodes have also been put into place at this time. Precision timing, approximately in the range of 5 to 10 ns, is required for 5G networks.

Due to their capability for several GNSS bands and powerful multipath avoidance, geodetic patch antennas are frequently utilized for timing applications.

2.  Radar navigation and positioning

Apps for location and navigation on mobile devices offered positions with a 5m accuracy.

Smart agriculture and self-driving automobiles both demand an accuracy of at least 10 cm.

It takes a top-notch geodetic antenna and receiver to attain this accuracy level.

A GNSS corrections service is necessary coupled with high-precision gear. RTK and precise point positioning are particularly popular correction techniques. Both strategies rely on readings of the antenna phase.

The chosen antenna needs to have a powerful multi-path mitigation system, a stable phase center, and low phase interference to retain phase lock in order to attain positioning precision greater than 10 cm.

3.  Unmanned aerial vehicles

Over recent years, UAV usage has skyrocketed. Experts in land surveying and remote sensing now have access to resources that were previously only available to governments and huge enterprises.

For usage with UAVs, GNSS antennas must support several constellations and multiple bands, be lightweight, power-efficient, compact, and have robust radio-frequency (RF) filtering.

Because they satisfy all the criteria outlined above and operate at their best without a ground plane, geodetic antennas are perfect for UAVs.

In order to maintain phase lock as the UAV spins and pitches, they also have a radiation pattern that offers significant middle to low-altitude angle reception.

4.  Land surveying

The most efficient GNSS antennae are necessary for this. Antennas for land survey rovers ought to be relatively lightweight and compact, with a PCV of no more than 5mm.

CORS and IGS stations use geodetic grade antennas, which are used for continuous operational referencing.

Since geodetic antennas have a 1mm PCV and accommodate multi-constellation, multiband, and high RF filtering, they are excellent for surveying.
