Manufacturer: | Categories: ,

The Eclipse P326 and P327 OEM are GNSS multi-frequency and multi-constellation boards from Hemisphere. Experience robust accuracy and reliability with the multi-frequency, multi-GNSS RTK and on-board Atlas L-Band. These modules receive signals from GPS, GLONASS, BeiDou, and Galileo and QZSS.



The Eclipse P326 and P327 OEM Boards offer robust, accurate, and reliable satellite tracking solutions. Low-power, multi-frequency, and multi-constellation tracking is made possible thanks to on-board multi-GNSS RTK and Atlas L-Band.
