multipath
Multipath can be eliminated/reduced via (1) antenna, and (2) receiver used. Check specs when buying an antenna and receiver.
"Multipath interference is a critical factor that significantly impacts the performance and accuracy of GNSS/GPS systems. It occurs when signals emitted by satellites reflect off various surfaces such as buildings, mountains, or the ground before reaching the GNSS antenna.

One of the most effective strategies we've embraced involves enhancing the design of antennas. Multi-path limiting antennas are tailored to reduce the effect of reflected signals, ensuring that the antenna primarily receives the direct signal from satellites. This design improvement plays a crucial role in high-precision tasks, including surveying and navigation in challenging environments.

Signal Processing Techniques
We've also leveraged sophisticated signal processing techniques to distinguish between the direct and reflected signals."
