Eclipse™ P326 and P327 Low Power, High Precision OEM Modules

Experience Accuracy and Reliability with Multi-frequency, Multi-GNSS RTK and Onboard Atlas®

These multi-frequency, multi-GNSS Hemisphere Eclipse P326 (34 pin) and P327 (20 pin) modules are based on an innovative platform that integrates L-band and receives Atlas® GNSS corrections on a single small board. Designed with this new platform, the overall cost, size, weight, and power consumption of the P326 and P327 are significantly reduced.

The P326 and P327 support 394 channels and are the first truly scalable board solutions that offer centimeter-level accuracy in either single-frequency or full performance multi-frequency, multi-GNSS, Atlas-capable mode. 

The small form factor (41mm x 71mm) 34-pin P326 module is a drop-in upgrade for many Hemisphere products, and the P327 module (41mm x 72mm) is a drop-in upgrade for standard 20-pin modules from other manufacturers.

This platform enables simultaneous tracking of all satellite signals including GPS, GLONASS, BeiDou, Galileo, and QZSS making it a 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.

Outstanding Capabilities
Powered by the Athena™ GNSS engine, P326 and P327 provide best-in-class, centimeter-level RTK. Athena excels in virtually every environment where high-accuracy GNSS receivers can be used. Tested and proven, Athena’s performance with long baselines, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation is of cutting edge. 

Together with SureFix™, Hemisphere’s advanced processor, the P326 and P327 deliver high-fidelity RTK information that results in guaranteed precision with virtually 100 percent reliability.

  • Advanced Technology Features
  • Integrated L-band adds support for Atlas GNSS corrections for meter to sub decimeter-level accuracy while new Tracer™ technology helps maintain position during correction signal outages.
  • The P326 and P327 also use Hemisphere’s all-new aRTK™ technology. Powered by Atlas, aRTK allows the P326 and P327 to continue generating RTK positions when RTK corrections become unavailable for a period of time. If they are Atlas-subscribed, they will continue to operate at the subscribed service level until RTK is restored.

The Eclipse P326 and P327 boards are ideal for UAVs,  machine control, land survey, agricultural, and marine applications.


  • GPS, GLONASS, BeiDou, and Galileo; QZSS ready
