Eclipse P326/P327 OEM Board

Hemisphere Eclipse P326 and P327 GNSS OEM Boards

The Ellipse P326 and P327 from Hemisphere GNSS have reached End of Life (EOL). Hemisphere GNSS recommends the Phantom 34 GNSS OEM Board as a suitable replacement for the P326 and the Phantom 20 GNSS OEM Board as a suitable replacement for the P327.



Track more signals for unparalleled positioning performance with Hemisphere GNSS’ new Eclipse P326 and P327 OEM modules. The latest technology platform enables simultaneous tracking of all satellite signals including GPS, GLONASS, Galileo, and L-band (QZSS ready) making it the most robust and reliable solution. The updated power management system efficiently governs the processor, memory, and ASIC making it ideal for multiple integration applications including handheld and battery powered devices.

The P326 and P327 are the most accurate and reliable OEM modules with two new advanced technology features; aRTK™ and Tracer™. Hemisphere’s all-new aRTK technology, powered by Atlas, allows the P326 and P327 to operate with RTK accuracies when RTK corrections fail. Tracer utilizes specialized algorithms to sustain positioning in the absence of corrections data.

With the Eclipse P326 and P327, positioning is scalable and field upgradable with all Hemisphere GNSS software and service options. Utilize the same centimeter-level accuracy in either single frequency mode, or employ the full performance and fast RTK initialization times over long distances with multi-frequency, multi-constellation GNSS signals. High-accuracy L-band positioning from meter to sub-decimeter levels available via Atlas correction service.

Leverage the compact size and easy integration in your design. The 34-pin P326 module is a drop-in upgrade for many Hemisphere products. P327 is a drop-in upgrade for existing designs using standard 20-pin modules from other manufacturers.
