PoInt One Standard Dev Kit User Manual 3

1. Introduction
This document provides technical guidance for the Point One Navigation Standard Dev Kit. The
Point One Standard Dev Kit allows the user to collect precise positioning data using Point One
FusionEngine API for various applications. It is available in a small miniPCIe form factor using
the Quectel LG69T navigation module.
This document provides information so that a user will be be able to:
●Connect the board to the host computer and GNSS antenna
●Configure device parameters and communication
●Install the Standard Dev Kit in a vehicle (if applicable)
●Run the device using the desktop or command-line applications and collect data
●Upgrade device firmware
During operation, the device will produce a 10 Hz standalone or RTK navigation solution.
Results can be output using the Point One FusionEngine
(https://github.com/PointOneNav/fusion-engine-client) and/or NMEA-0813 protocols.
For RTK operation, corrections must be supplied to the device using RTCMv3 MSM4-7
messages. Corrections may be passed directly to the device via either serial UART. Corrections
can be provided by a local base station, Point One's Polaris corrections network, or an
alternative NTRIP server using either the Point One Navigation desktop application or the
included Python p1_runner command-line application.
Point One Navigation Desktop application is freely available to interface with the Standard Dev
Kit for configuration, data collection, and evaluation. The Desktop application is available for
Linux, Windows, or Mac OS.
Similar to the Desktop application, the Python p1_runner application may be used on the
command line to connect to the device over serial and performs the following:
●Connect to a Polaris or NTRIP server and provide incoming RTCM corrections data to
the device over serial
○NMEA GPGGA position messages automatically will be forwarded to the NTRIP
server to associate the device with a corrections data stream
●Extract and display position solutions
●Relay positioning data on a TCP port for use with user applications
PoInt One Standard Dev Kit User Manual 4

●Log FusionEngine, RTCM, NMEA data produced by the device for post-processing and
diagnostic purposes
In addition, the provided Python config_tool command-line application may be used for
configuring device settings.
For details on connecting an LG69T-AM/AP navigation engine with a secondary LG69T-AH
heading measurement engine, see the Point One Standard Dev Kit AH Heading Firmware
Application Note.
For details on using a Quectel LG69T evaluation board, see the Quectel LG69T EVB Application
Note.

2. Requirements
●Hardware
○Point One Standard Dev Kit
○L1/L5 GNSS antenna
○USB-to-miniPCIe carrier board or miniPCIe interface to host computer
●Software
○LG69T AM, AP, or AH release package containing the latest firmware and tools
■Latest firmware version available at
https://pointonenav.com/docs/#standard-dev-kit
○Windows, Linux (kernel v5.9 or later), or Mac OS
○Point One Navigation Desktop application, included p1_runner application, or
user developed interface software built on Point One open source tools
●Connectivity
○The Point One Standard Dev Kit should be connected to a host computer with
internet connectivity to receive GNSS corrections for RTK operation
NOTE: DRIVERS ARE REQUIRED FOR WINDOWS AND MACOS
When using Windows, install the CP210x Windows Drivers v6.7.6 or later from
https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers. The default universal
driver included with Windows can cause significant unexpected data loss on some machines.
When using Mac, install the CP210x VCP Mac OSX Driver v6.0.0 or later from
https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers.
When using Linux, use the CP210x driver included with Linux kernel version 5.9 or later
(included in Ubuntu 21.04 and later). Before 5.9, the driver had an issue that can cause
unexpected data loss on some machines.
The Point One Standard Dev Kit offers three different types of firmware available for use: AM,
AP and AH.
The AM firmware uses the on board GNSS receiver and supporting machine to stream RTK
corrections and provide precise location.
PoInt One Standard Dev Kit User Manual 6

The AP firmware integrates the GNSS receiver with the onboard IMU and optional wheel
speed/tick sensor data in order to provide Dead Reckoning abilities in tough GNSS
environments where it is difficult to provide an accurate position with GNSS alone. This
firmware is only compatible with LG69T-AP modules.
The AH firmware is used for dual antenna heading configurations and must be used in
conjunction with another AM or AP module. Details on the AH use and configuration can be
found in the Point One Standard Dev Kit AH Addendum manual.
By default, boards are flashed with the latest AM firmware. See Section 7.1 to update firmware
using the Point One Desktop Application to the latest version.

3.2 Communications Interface
The Point One Standard Dev Kit supports Point One FusionEngine messages and NMEA-0183 messages,
over USB on the miniPCIe connector. There are two UARTs available on the LG69T device.
By default, serial UART1 is configured to output NMEA-0183 messages at 460800 baud. UART2 is
configured to output an interleaved stream of FusionEngine, NMEA-0183, and RTCM messages. Output
configuration can be changed using FusionEngine configuration messages (see 6.2.4 Enabling/Disabling
Output Message Types). Both serial ports are configured for 8 bits, no parity, 1 stop bit (8N1).
During operation, the device will produce a 10 Hz position solution after initialization.
Note: In Windows, UART1 is named "Standard COM Port" and UART2 is named "Enhanced COM Port".
In Linux, UARTs 1 and 2 typically appear as /dev/ttyUSB1 and /dev/ttyUSB0 respectively.
Note: We highly encourage the use of the Point One FusionEngine binary protocol over legacy
NMEA-0813 messages. The FusionEngine protocol includes more detailed information than is
available in standard NMEA messages.
PoInt One Standard Dev Kit User Manual 9

The device can be operated with either the Point One Navigation Desktop application, or the
p1_runner command-line application included with the release. Both applications include a built-in
NTRIP client, support for Point One's Polaris corrections network, and data logging support for
diagnostics.
The device supports the following input and output message types:

When messages from multiple protocols are enabled, they will be interleaved in a single data stream.
Note that some NMEA clients may not support mixing non-ASCII data.
If desired, the output configuration can be changed using FusionEngine SetMessageOutputRate
messages.
Corrections data and control messages may be sent to either UART, however RTK corrections may
only be sent to one port at a time.
Note: If the RTK base station is operating with MSM7 and using station ID 1, the station ID reported in
the user output will be 4095.
