How far can you push RTK corrections using LoRa? In this video, we test a long-range base and rover setup using the SparkPNT Facet with a built-in 915MHz, 1W LoRa radio, achieving reliable RTK accuracy over miles of line-of-sight distance.
We demonstrate a real-world setup transmitting corrections from a base station positioned on a known survey monument to a rover nearly 9 miles away, while maintaining centimeter-level accuracy.
• LoRa enables long-range correction transmission without internet
• RTK fixes can be maintained even with intermittent packet delivery
• Line-of-sight plays a critical role in performance
• Built-in radios simplify base + rover deployments in the field
