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.

H220™ L1 GPS, GLONASS, BeiDou, Galileo and
QZSS
Yes
What’s Included
The H220 is available in two configurations:
H220 OEM board only - designed for integrators who are familiar with H220 OEM board
integration
H220 OEM board and Universal Development Kit - designed for integrators who are
new to H220 integration (assembly required: OEM board and Universal Development kit
sold separately)
The Universal Development Kit is designed to work with various Hemisphere OEM boards and
includes an enclosure with carrier board, adapter boards, and various cables.
For more information on the Universal Development Kit go to www.hemispheregnsss.com and
navigate to the Precision OEM Products page.
Integrating the H220
Successful integration of the H220 within a system requires electronics expertise that includes:
Power supply design
Serial port level translation
Reasonable radio frequency competency
An understanding of electromagnetic compatibility
Circuit design and layout
H220 Integrator Guide Chapter 1 - Introduction Page 4 of 28
The H220 GNSS engine is a low-level module intended for custom integration with the following
general integration requirements:
Regulated power supply input (3.3 VDC ± 5%) and 1.7 mA continuous current
Low-level serial port (3.3 V CMOS) and USB port communications
Radio frequency (RF) input to the engine from a GNSS antenna is required to be actively
amplified (10 to 40 dB gain)
GNSS antenna is powered with a separate regulated voltage source up to 15 VDC
maximum
Antenna input impedance is 50 Ω
Antenna voltage input is 15 VDC maximum
Antenna gain input range is 10 to 40 dB
Features of the H220
Some notable features of the H220 are:
Multi-channel GNSS engine (12 L1CA GPS, 12 L1P GPS, 12 L1 GLONASS, 22 B1
BeiDou, 12 E1 Galileo, 4 L1 QZSS and 3 channels dedicated to SBAS tracking)
Sub-meter horizontal accuracy 95%
Raw measurement output (via documented binary messages)
Position and heading update rates of 50 Hz maximum
Quick times to first fix
Four full-duplex serial ports, a dedicated RTCM input port, and two USB ports (one USB
host, one USB device)
1 CAN NMEA2000, ISO-11783
1 PPS timing output
Event marker input
L-band capable
Fast RTK acquisition and reacquisition times
10 cm RTK-enabled heave accuracy
Improved heading accuracy with different baseline lengths (up to 5 m)
Same form factor as Hemisphere GNSS' Crescent® Vector II OEM board
Note: See Appendix B, Technical Specifications for complete H220 specifications.
Configuring the H220
The H220 has four communication ports: A, B, C, and D. Ports A, B, and C are fully independent
and can have different messages output at different rates. You can configure each of these ports
for external correction input or output binary message information or RTCM corrections from an
outside source. You can also configure the output of ports A, B, or C through any of these ports.
Configure the baud rates if necessary; the default is 19200 for Ports A, B, and C.
Port D is reserved for RTCM differential corrections and may be used by the Hemisphere
GNSSSBX-4™ board (not included with H220).
You can configure the H220 to use the following differential operation modes:
SBAS
Beacon (with optional SBX-4 board)
L-band
External corrections
H220 Integrator Guide Chapter 1 - Introduction Page 5 of 28
Message Interface
The H220 uses a NMEA 0183 interface, allowing you to easily make configuration changes by
sending text-type commands to the receiver.
The H220 also supports a selection of binary messages. There is a wider array of information
available through the binary messages, plus binary messages are inherently more efficient with
data. If the application has a requirement for raw measurement data, this information is available
only in a binary format.
For more information on NMEA 0183 commands and messages as well as binary messages refer
to the Hemisphere GNSS Technical Reference Guide.
Using PocketMax4 to Communicate with the H220
Hemisphere’s PocketMax4 is a free utility program that runs on your Windows PC or Windows
mobile device.
Simply connect your Windows device to the H220 via the COM port and open PocketMax4.
The screens within PocketMax4 allow you to easily interface with the H220 to:
Select the internal SBAS, external beacon, or RTCM correction source
and monitor reception (beacon optional)
Configure GNSS message output and port settings
Record various types of data
Monitor the H220 status and function
PocketMax4 is available for download from the Hemisphere GNSS website.
