Leo Store - Hemisphere GNSS - Phantom™ 20 & 34 GNSS OEM Boards 1

Phantom™ 20 & 34 GNSS OEM Boards

Multi-Frequency, Multi-GNSS RTK & ATLAS


Track more signals for unparalleled positioning performance with Hemisphere GNSS’ new Phantom™ 20 & 34 GNSS OEM Boards. The latest technology platform enables simultaneous tracking of all satellite signals including GPS, GLONASS, BeiDou, Galileo, QZSS, NavIC (IRNSS) and L-band making it the most robust and reliable solution for GIS, agriculture, and machine control. The power management system efficiently governs the processor, memory, and ASIC making it ideal for multiple integration applications.


The Phantom 20 and 34 are the most accurate and reliable OEM modules with two advanced technology features; aRTK™ and Tracer™. Hemisphere’s aRTK technology, powered by Atlas, allows the Phantom 20 and 34 to operate with RTK accuracies when RTK corrections fail. Tracer uses specialized algorithms to sustain positioning in the absence of correction data.
