Frequently Asked Questions about Multi-Element GNSS

With the modernized Global Navigation Satellite System or GNSS, antennas now play an important role in the receiving system design. Multi-element GNSS simulation is a great tool to help you get familiarized with how the system works and how you can use it to your advantage. Although there are still a few people who overlook the importance of antennas as part of the GNSS equipment, understanding its relevance to the system can play a major role when it comes to accurate GNSS positioning. Here are a few interesting questions that most people have when it comes to GNSS.

What are the technical challenges that multi-GNSS encounters when it comes to operations and antenna designs?

According to Inside GNSS, companies using GNSS need to incorporate the latest version, together with the latest antenna and receiver designs to fully utilize its benefits. New challenges may arise as soon as the full E5 band needs support to provide a high-performance application.

What are the benefits multi-element GNSS has to offer?

Utilizing multiple GNSS elements can provide various support, especially when it comes to navigation application, GIS application, machine control application, agricultural application, and survey application. However, due to variable GLONASS satellite frequencies, a GLONASS observation bias may be visible once you compare the data from various manufacturers. According to UNOOSA, Trimble and LEICA have exhibited GLONASS

What are the major metrics used for assessing the efficiency of its performance?

A typical GNSS antenna is commonly characterized as the system levels, component, and requirements to assess its performance. Various metrics, such as the pseudorange residuals, signal carrier-to-noise ratio, and user domain solution errors, can be used to assess the entire performance of the GNSS receiver carefully.

These are a few of the most common questions that most people have when it comes to multi-element GNSS. Using a simulator can help decrease the chances of encountering an error. It can also help achieve more accurate results.
