Introduction
The Crescent® Vector™ H220 GNSS OEM board is the next generation, single-frequency, high-
performance GNSS heading, positioning, and altitude module available from Hemisphere GNSS.
The H220 provides integrators with an opportunity for developing sophisticated marine, navigation,
and land applications in challenging, dynamic environments. The H220 uses Hemisphere’s
advancements in Vector technology, advanced multipath mitigation techniques, and Hemisphere’s
patented Multifunction Application.
H220 is capable of providing heading of 0.04° with a 5-meter antenna baseline and either RTK or
SBAS positioning depending on your location requirements. With Atlas corrections, the H220 can
obtain instant submeter accuracy worldwide while being more robust than SBAS even in SBAS
regions.
Integrate the robust H220 GNSS OEM board into your applications to experience exceptional heading,
positioning, and attitude performance in a compact size. Diversity and cost savings make it an ideal
part of your solution for system integrators.
Product Overview and Features
Designed with a new hardware platform, it offers true scalability with centimeter-level accuracy in either
single-frequency mode or Atlas-capable mode that supports fast RTK initialization times over long
distances. The H220 offers fast accuracy heading of better than 0.30 degrees at 0.5 m
antenna separation in ideal conditions and aiding gyroscope and tilt sensors for temporary GNSS
outages. The 109-mm x 71 mm module with 34-pin header is a drop-in upgrade for existing designs
using the H200.
The latest technology platform enables simultaneous tracking of all L1 constellations including
GPS, GLONASS, BeiDou, Galileo, and QZSS, making it robust and reliable. The updated power
management system efficiently governs the processor, memory, and ASIC, making it ideal for
multiple integration applications. The H220 offers flexible and reliable connectivity by supporting
Serial, USB, and CAN for ease-of-use and integration. Optional output rates of up to 50 Hz are also
supported.
Advanced Technology Features
The H220 offers integrated L-band support for Atlas corrections providing global sub-meter
position accuracy while Hemisphere’s Tracer™ technology helps maintain position during
correction signal outages.
Fitted with Hemisphere’s patented Crescent receiver technology, the H220 computes heading and
DGPS position using L1 GPS,GLONASS, BeiDou, Galileo and QZSS. Develop robust marine
navigation and land solutions in a world full of complex dynamic environments through Hemisphere
GNSS’ advancements in Vector technology. The H220 brings a series of new features to the
patented Crescent Vector technology including a more robust heading solution and excellent
positioning through RTK. The H220 outputs heading, pitch, and roll.
Note:
Throughout the rest of this manual, the Crescent® Vector™ H220 OEM board is referred to
simply as the H220.
