Gnss - NetModule NB3710-LWA User Manual

5.3.8. GNSS

Administration
The GNSS page lets you enable or disable the GNSS modules present in the system and
can be used to configure the daemon that can be used to share access to receivers without
contention or loss of data and to respond to queries with a format that is substantially
easier to parse than the NMEA 0183 emitted directly by the GNSS device.
We are currently running the Berlios GPS daemon (version 3.15), supporting the new
JSON format. Please navigate to
tion about how to connect any clients to the daemon remotely. The position values can
also be queried by the CLI and used in SDK scripts.

GNNS Module Configuration
Enable or disable the GNSS module
The mode of operation, either standalone or assisted (for
A-GPS)
The type of the connected GPS antenna, either passive or
actively 3 volt powered
The desired accuracy in meters
The amount of time to wait between fix attempts
GNNS Server Configuration
The TCP port on which the daemon is listening for incoming
connections
Specifies where clients can connect from, can be either
everywhere or from a specific network
Specifies how data transferal is accomplished when a client
connects. You can specify on request which typically re-
quires an R to be sent. Data will be sent instantly in case of
raw mode which will provide NMEA frames or super-raw
which includes the original data of the GPS receiver. If the
client supports the JSON format (i.e. newer libgps is used)
the json mode can be specified.
