I just wanted to share the actual state of our investigation here as well.
Based on the full system reports of the two Reach RS3s, we couldn’t find any issues on the hardware side. Everything seems to be operational.
As the next step, we evaluate the logs from the units. In the base logs we discovered the solution status switched to Single when the corrections stopped coming to the unit:
Since there were no disconnections when the RS3 units were close to each other, the reason most likely lies in the environment. LoRa is a low-powered radio that requires a clear line of sight and no RF interference for the best performance. To improve its performance in a harsh environment, we’d recommend trying the recommendations from this support tip.
For example, sometimes, you can increase the LoRa baseline by lowering the air data rate. If the receiver transmits less data, the LoRa radio can show a better range. That could also affect the comparison tests of Reach RS and Reach RS3.
At its core, the solution calculation of Reach RS3 works the same way as it does on the Reach RS2 and Reach RS2+. The tilt compensation happens after that, so it shouldn’t affect the calculations’ stability.
