2 Overview

This chapter introduces the P5 GNSS reference receiver (“the receiver”). This

receiver makes it easy to set up a powerful and reliable Continuously Operating

Reference Station (CORS) or to collect data from temporary field locations.

The receiver is ideal for the following infrastructure applications:

(1) As part of a GNSS Infrastructure network in conjunction with CHC Reference

Station Network (CPS) software.

(2) As part of a permanent reference station with or without supporting software.

(3) A temporary field base station to broadcast RTK corrections and collect

observations for post-processing.

2.1 Receiver Framework

The receiver integrates the multi-frequency GNSS technology into specialized

processing and communications framework. The receiver can operate as a

standalone reference station, or it can be integrated into a scalable network.

With an Internet Protocol (IP) as the primary communications method, the user can

use public domain tools, such as a web browser and FTP client, to configure the

receiver and access logged data files.

Notes: 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 a password protected login for

configuration changes and/or file access.

Use the network management features to create a base/rover configuration with a

variety of operating modes. The user can then enable those modes as necessary

instead of switching the global state of the receiver from one mode to another. For

example, the user can configure various streaming services with different

configurations (such as any combination of the 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 features and many more, shift the model of a GNSS receiver toward the

concept of a "network appliance".
