2.1.1 The Network Appliance Concept
Traditionally, a GNSS receiver has one operator. That person is the only user of the
receiver, so they can change settings without affecting other users.
With the P5 GNSS reference receiver, an operator can configure a receiver once, and
then make it available as a network appliance for general use by one or more users
(or clients).
This network appliance concept lets the user 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, the
user needs to 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 streaming services may be configured on different ports, for example, with
different data rates or data combination. To obtain 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:

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 can provide one or more streaming or query services over an RS-232
serial port or a TCP/IP port: 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. The client simply connects to the port that is streaming the required
information.
