GNSS RTK receivers: comparison of the accuracy

Today I want to show the positioning accuracy of various RTK receivers. Compare them with the Trimble R8, a well-known and relatively expensive brand. Trimble products have a long service life, have proven accuracy and represent a global brand.

Who we are?
Geometer International has been developing GNSS receivers and software since 2010. We offer high-accuracy solutions at lower prices. We suggest watching this video for those who would like to see that high accuracy is not just about expensive branded products.
Geometer International is a company that produces RTK receivers as accurate and reliable as the expensive branded ones. But our products are very noticeably different in price.
Therefore, in today's tests, we connect to the same base station, which is located 200 meters from our location.
It is a multi-frequency base station (L1, L2, and L5) with support for satellite systems: GPS, GLONASS, GALILEO, and BEIDOU.
We set up a tripod on which we only changed receivers, while the tripod remained in the same place.
We consider the location of the point to be the same for all rover receivers. List of receivers used in this video:
Trimble R8 receiver with TSC2 controller, which has 220 channels with support for GPS, GLONASS on frequencies L1, L2, L5
GM RTK receiver that has 184 channels with full-constellation support on L1, L2 frequencies
The Walker RTK receiver also has 184 channels with full-constellation support on L1, L2 frequencies.
The 2nd generation GM PRO receiver has 965 channels with full-constellation support also and on full L-band frequencies
Instead of controllers, we use an ordinary smartphone with a mobile application with receivers manufactured by Geometer International.
