The new Vector Eclipse H328 is a part of the Hemisphere GNSS line of low-power, high-precision, positioning and heading OEM boards. The multi-frequency, multi-GNSS H328 is an all-signals receiver board that includes Hemisphere’s new hardware platform and integrates Atlas GNSS Global Correction Service.
In addition to a new hardware platform, the overall cost, size, weight and power consumption of the H328 are reduced. It offers scalability with centimeter-level accuracy in either single-frequency mode or full performance multi-frequency, multi-GNSS, Atlas-capable mode that supports fast RTK initialization times over long distances. The H328 offers accuracy heading of better than 0.17 degrees at 0.5 meter antenna separation and aiding gyroscope and tilt sensors for temporary GNSS outages. The 60-millimeter-by-100-millimeter module with 24-pin and 16-pin headers is a drop in upgrade for existing designs using this industry standard form factor.
The latest technology platform enables simultaneous tracking of all satellite signals including GPS, GLONASS P-code, BeiDou, Galileo and QZSS. The updated power management system is designed to efficiently govern the processor, memory and ASIC. The H328 supports Serial, USB (On-The-Go with future firmware upgrade), CAN, Ethernet, and SPI for ease-of-use and integration. Optional output rates of up to 50 Hz are also supported.
Integrated L-band adds support for Atlas GNSS global corrections for meter- to sub-decimeter-level accuracy while Tracer technology helps maintain position during correction signal outages. The H328 also uses Hemisphere’s RTK technology, powered by Atlas. This feature allows the H328 to operate with RTK accuracies when RTK corrections fail. If the H328 is Atlas- subscribed, it will continue to operate at the subscribed service level until RTK is restored.
