As Global Navigation Satellite Systems (GNSS) technology advances, our reliance on location-based services grows. According to research by MarketsandMarkets, the global GNSS chip market is projected to grow to $4.9 billion by , representing a remarkable 48% growth over the next five years. The rise of autonomous vehicles, advanced robotic applications, precision agriculture, and more is spurring this demand.

In recent years, there has been a trend towards combined technologies (sensor fusion, PPP, RTK, etc.) in GNSS systems, resulting in productivity gains and increasingly accurate and versatile devices. However, this adds further complexities and challenges for antenna design.

Your base should be in a nice open location with a good clear view of the sky.

I use a survey style antenna with the M2 for base with great results. An mcx to (sma or tnc) adapter to get the M2 to adapt.

Survey style is the more accurate antenna. In perfectly flat, nicely open territory with little for trees or obstructions.

But if you have particularly crowded, overgrown, overhanging obstacles, hilly terrain, problems with losing gps signal. Helical antennas are a much better choice.

The tallysman hc871 and 882 are really great choices. You will not be disappointed tallysman antenna in rover position. Helical antennas also do not suffer from dust accumulation.

Tallysman is a great, and fairly priced brand building high quality antennas. I have also had success with these two, especially the stubby harxon hx-901. The HX 607 performed well but sticks up fairly high, Its a bit taller than my thumb.
