Hi everyone,
Thank you for the feedback! I agree that you should be able to achieve much longer baselines with the LoRa radio than the 60 meters mentioned. However, if you compare the firmware after version 31.0, the difference can hardly be related to the update. Let me share more context on that.
In firmware 31.0, we’ve reduced the Age of Differential (AoD) threshold to 10 seconds to ensure a reliable and accurate solution. Previously, a rover could hold a Fix solution even if it hasn’t received base corrections for a while (up to 60s AoD). So, you indeed could reach a longer baseline in a harsh environment. In proper environmental conditions, when the correction signal is not disrupted, both firmware versions should show similar results.
We haven’t introduced other changes recently that would affect LoRa’s performance. Following our tests and cases that we’ve helped with, there are no confirmed bugs related to LoRa radio either. In most situations, if there are difficulties achieving a long baseline, we can solve it by thoroughly checking and adjusting the setup. Because of that, and since we’re continuously adding new features to both software and firmware, we don’t support downgrades.
Environmental conditions are the most common factor affecting the LoRa connection. For example, there may not be a clear line of sight between the receivers, or electronics and power lines may affect the radio transmission. That’s why it’s worth comparing the baseline in different surveying locations. You can also follow this support tip for recommendations on establishing a good LoRa connection. If it doesn’t help achieve a longer baseline, please get in touch with us, and we’ll be sure to check everything.
