gpsNumTrackSats OBJECT-TYPE
SYNTAX INTEGER (0..8)
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION "The number of GPS satellites tracked."
::= { gps 2 }
gpsNumCurrentSats OBJECT-TYPE
SYNTAX INTEGER (0..8)
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"Current number of GPS satellites used in position and time fix
calculations. The number of satellites available depends on how long
the time server has been up, the time of day and the total amount of
clear sky as seen from the GPS antenna. Because of the high frequency
of GPS radio signals, GPS antennas must have unobstructed line of sight
from the antenna to the satellite to receive data."
::= { gps 3 }
gpsSatTrackMode OBJECT-TYPE
SYNTAX INTEGER (0..3)
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"Mode of operation for satellite tracking. See section 3.20 of the
users manual for a complete description of these modes. Generally,
modes 0 and 1 are used for time applications. Mode 2 is useful for
more accurate position information when the unit is stationary, or
slowly moving and mode 3 is for accurate position information when the
unit is moving quickly."
::= { gps 4 }
gpsSatMaxSigStrength OBJECT-TYPE
SYNTAX INTEGER (0..30)
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"Strongest signal strength of all tracking satellites in Trimble linear
units. Generally, this number should be 4 or greater for good
reception."
::= { gps 5 }
gpsAltitude OBJECT-TYPE
SYNTAX INTEGER (-2147483647..2147483647)
MAX-ACCESS read-only
STATUS deprecated
DESCRIPTION
"Altitude of the GPS antenna in centimeters above, or below the
WGS-84 reference ellipsoid. The reference ellipsoid is a rotated
ellipse that is centered on the Earth's center of mass. The surface
of the ellipsoid is not necessarily the same as sea level. The
ellipsoid surface may be as much as 100 meters different from actual
sea level."
