P306/P307 Integration
Successful integration of the P306/P307 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

P306/P307 Integrator’s Guide Chapter 1 - Introduction Page 7 of 39
The P306/P307 GNSS engine is a low-level module intended for custom integration with the
following general integration requirements:
Regulated power supply input (3.3 VDC ± 3%) and 700 mA continuous
Low-level serial port (3.3 V CMOS) and/or 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 50Ω
Common Features of Eclipse Boards
372-channel GNSS engine
Sub-meter horizontal accuracy 95%
Raw measurement output (via documented binary messages)
Position and heading update rates of 20 Hz max
COAST™ technology that provides consistent performance with correction data
e-Dif®-ready - a base station-free way of differentially positioning
L-Dif™-ready – Local differential is a proprietary Hemisphere GNSS method where a
specialized set of messages are relayed between two Eclipse receivers
Quick times to first fix
Four full-duplex serial ports
USB device port only (P307)
USB host and USB device ports (P306)
1 PPS timing output
Event marker input
Message Interface
The P306/P307 uses a NMEA 0183 interface, allowing you to easily make configuration changes by
sending text-type commands to the receiver.
The P306/P307 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.
Note:
For complete specifications of Eclipse boards, see Appendix C, “Technical Specifications.”

P306/P307 Integrator’s Guide Chapter 1 - Introduction Page 8 of 39
Using PocketMax3™ to Communicate with the P306/P307
Hemisphere’s PocketMax3™ is a free utility program that runs on your Windows PC or Windows
mobile device. Simply connect your Windows device to the P306/P307 via the COM port and open
PocketMax3™.
The screens within PocketMax3™ allow you to easily interface with the P306/P307 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 receiver’s status and configuration
PocketMax3™ is available for download from the HGNSS website.

P306/P307 OEM Board Key Features
With its small form factor, low power consumption, and simple on-board firmware, the
P306/P307 is an ideal solution for integrators, offering scalability and expandability from L1
GNSS with SBAS to L1/L2 GNSS, GLONASS BeiDou and Galileo (with RTK capability).
P306 is a drop-in replacement for Hemisphere GNSS’ Crescent® and mini
Eclipse receivers (34-pin) and provides Atlas support with the optional
Hemisphere GNSS LX-3™ OEM board
P307 has a mechanical design compatible with popular after-market products
(20-pin)
The reliable positioning performance of P306/P307 is further enhanced through Eclipse RTK
and COAST DGPS technology.
With P306/P307, RTK performance is scalable. Utilize the same centimeter-level accuracy
in either L1-only mode, or employ the full performance of fast RTK performance over long
distances with L1/L2 GNSS signals. Hemisphere GNSS’ SureTrack technology provides
peace-of-mind knowing the RTK rover is making use of every satellite it is tracking. Even
satellites not tracked at the base benefit from fewer RTK dropouts in congested
environments, faster reacquisition, and more robust solutions due to better cycle slip
detection.
Patented COAST software enables select Hemisphere GNSS receivers to utilize aging
DGPS correction data during times of interference, signal blockage, and weak signal. The
receiver will coast and continue to maintain sub-meter positioning for 40 minutes or more
without a DGPS signal.
