5.3.8. GPS
Administration
The GPS page lets you enable or disable the GPS 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 GPS device.
We are currently running the Berlios GPS daemon (version 2.37), please navigate to
http://gpsd.berlios.de
The GPS values can also be queried by the CLI and used in SDK scripts.
Administrative status: Enable or disable GPS reception
Antenna type: The type of the connected GPS antenna, either active or passive
Server port: The TCP port on which the daemon is listening for incoming connections
Allow clients from: Specifies where clients can connect from, can be either everywhere
or from a specific network
Clients start mode: Specifies how client reception is started upon connect. You can
specify on request, which typically requires an R to be sent, or raw/super-raw
mode which will transmit NMEA frames to the client instantly
Position
This page shows the current position of the box together with a location map.
Information
This pages provides further information about the satellites in view and values derived
from them:
Latitude: The geographic coordinate specifying the north-south position
Longitude: The geographic coordinate specifying the east-west position
Altitude: The height above sea level of the current location
Satellites in view: The number of satellites in view as stated in GPGSV frames
Speed: The horizontal and vertical speed in meter per second as stated in GPRMC
frames
Satellites used: The number of satellites used for calculating the position as stated in
GPGGA frames
Dilution of precision: The dilution of precision as stated in GPGSA frames
Furtheron, each satellite also comes with the following details:
PRN: The PRN code of the satelitte (also referred as satellite ID) as stated in GPGSA
frames
Elevation: The elevation (up-down angle between the dish pointing direction) in degrees
as stated in GPGSV frames
