Product description
The SparkFun Triband GNSS RTK Breakout features the UM980 GNSS high precision RTK position module from Unicore Communications. The UM980 is a 1408-Channel GNSS Receiver based on the Nebulas IVâ„¢ that is able to simultaneously track GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b/E6, Beidou B1I/B2I/B3I/B1C/B2a/B2b, QZSS L1/L2/L5, and SBAS.
With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail. When an RTK solution is reached, the module can achieve a horizontal accuracy of about 8mm (~0.3 inches) and vertical accuracy of 15mm (~0.59 inches). The UM980 is capable of both rover and base station operations.
