1 Introduction
The P3DT GNSS Reference Receiver User Guide describes how to set up and use the
CHC® P3DT™ GNSS reference receiver.
In this manual, “the receiver” refers to the P3DT GNSS reference receiver unless
otherwise stated.
Even if you have used other Global Navigation Satellite Systems (GNSS) products
before, CHC recommends that you spend some time reading this manual to learn
about the special features of this product. If you are not familiar with GNSS, go to
www.chcnav.com for an interactive look at CHC and GNSS.
1.1 About the Receiver
The P3DT GNSS reference receiver (“the receiver”) is a multiple-constellation and
multiple-frequency GNSS receiver.
You can use the front panel of the receiver or an office computer to configure the
receiver, download data or publish it on your company intranet or the Internet. The
receiver makes it easy for you to set up a powerful, flexible, and reliable reference
station for continuous operation.
The receiver can serve as common geodetic reference receiver. It can be main
component in a Continuously Operating Reference Station (CORS), streaming data to
CHC GNSS Infrastructure software. It can also work well as a campaign receiver prior
to permanent deployment. The receiver makes an excellent portable RTK base
station with its internal battery. It also has specialized capabilities that make it an
excellent reference receiver for scientific applications.
1.2 Technical Support
If you have any problem and cannot find the information you need on CHC website
(www.chcnav.com), please contact local CHC dealer from which you purchased the
receiver(s).

2 Overview
This chapter is a introduction about the P3DT GNSS reference receiver (“the
receiver”). This receiver makes it easier for users to set up a powerful and reliable
Continuously Operating Reference Station (CORS) or temporary data collection in the
field.
The receiver is an ideal choice for the following applications:
As part of a GNSS Infrastructure network integrated with CHC Precision Service
(CPS) software.
As part of a permanent reference station with or without related software.
As a temporary base station in field to broadcast RTK corrections and collect
observation data for post processing.
2.1 Receiver Framework
The receiver integrates multi-frequency GNSS technology into a specialized
processing and communication framework. The receiver can either operate as a
stand alone reference station or be integrated into a scalable network.
Using IP (Internet Protocol) as primary communications method, users can use public
domain tools such as a web browser or FTP client, to configure the receiver and
access logged data files.
NOTE - All references to the Internet refer to either a Wide Area Network (WAN) or a
Local Area Network (LAN) connection.
The receiver adopts a secured system that requires password to log in for further
receiver configuration and data access.
Use the network management features to create a base/rover configuration with a
variety of operating modes. You can then enable those modes as necessary instead
of switching the global state of the receiver from one mode to another. For example,
you can configure a number of streaming services with different configurations (such
as any combination of data stream, sample interval) on different TCP or UDP ports.
To activate one or more modes, open the connection to the specific port. This allows
multiple clients to access any given streaming service.
These kinds of features, shift the model of a GNSS receiver toward the concept of a
"network appliance".

8
2.1.1 The Network Appliance Concept
Traditionally, a GNSS receiver has only one user. Thus that only one user can change
the settings without affecting other users.
However, P3DT has more than one users. That means an operator can make it
available as a network appliance for more than one users (or clients).
This network appliance concept brings multiple services to many other users via
LAN(Local Area Network) or WAN(Wide Area Network) such as the Internet. Only a
few small changes is needed after the receiver was set up.
lets you set up the receiver to provide one or more services that one or more users
can access through a Local Area Network (LAN) or a Wide Area Network (WAN), such
as the Internet. Once the receiver is set up, you need make only minimal changes, if
any, to the receiver configuration.
When the receiver is operating as a network appliance, it provides services to all
users attached to the receiver through the network.
Different streamed services may be configured on different ports, for example, with
differing data rates or data combination. To obtain a service, the client has only to
connect to a specific port. In this way, most users do not need to control the receiver.
Changing global settings, such as masks, will affect all users of all services.
The receiver provides the following standard configuration and data logging services:
Use
To perform
HTTP
All manual and automated configuration operations to
manage the logged data file space.
FTP
Remote manual and/or automated operations to
manage the logged data file upload path.
2.2 Receiver Services
The receiver more than one data streaming and query services either through a
RS-232 serial port or a TCP/IP port:

9
Streaming service
Anyone with authorized access can obtain streamed information, such as GNSS
measurements or RTCM corrections, without having to control or issue commands to
the receiver. Users only need to connect with the port that is streaming the required
information.

2.4 Insert Battery and SIM Card
This receiver can withstand harsh environment that typically occurs during CORS
installation. However, it is a high-precision electronic instrument and should be
treated with reasonable care.
CAUTION – Operating or storing the receiver outside the specified temperature
range can damage it.
2.5 Electronic Interfaces
High-power signals from a nearby radio or radar transmitter can overwhelm the
receiver circuits. This does not harm the instrument, but it can prevent the receiver
electronics from functioning correctly.
Avoid locating the receiver or antenna within 400 meters of powerful radar,
television, or other transmitters or GNSS antennas. Low-power transmitters, such as

10
those in cell phones and two-way radios, normally do not interfere with receiver
operations.
