Receiver Status - Position
|
|
The Receiver Status - Position page shows general information
about the current position solution, as derived from satellite
measurements. This information includes:
-
Position - The current position solution in the satellite
reference system.
-
Lat - Latitude in degrees, minutes and seconds.
-
Lon - Longitude in degrees, minutes and seconds.
-
Hgt - Height above the ellipsoid in meters.
-
Velocity - The apparent velocity of the receiver derived
from the satellite doppler frequency shifts.
-
North - The apparent velocity in the grid north direction.
-
East - The apparent velocity in the grid east direction.
-
Up - The apparent velocity in the vertical direction.
-
Horiz - The apparent velocity in the horizontal plane, expressed
as meters per second, miles per hour, and kilometers per hour.
-
Heading - The apparent direction the receiver is moving in
the horizontal plane, expressed in degrees clockwise from true
north.
Note that a stationary receiver may show some small velocity due to
small inherent uncertainties and noise in GPS measurements.
-
Satellites Used - The list of satellites used in the
current position solution.
-
Receiver Clock - Information about the receiver's time source.
-
Offset - The difference between the current time as reported by the
clock and the time derived from the GPS position solution.
-
Drift - The rate at which the receiver clock is drifting from the
time derived from the GPS position solution.
Note that if clock steering is
enabled, these two values will be zero.
-
Dilutions of Precision - These express the quality of various
values derived from GPS measurements, as a function of the current
satellite geometry relative to the GPS receiver. The smaller the
value, the better the quality of the solution, and the higher
probability of an accurate result.
-
PDOP
- Position DOP; indicates the quality of the
overall position solution.
-
HDOP
- Horizontal DOP; indicates the quality of the
horizontal position, excluding the vertical component.
-
VDOP
- Vertical DOP; indicates the quality of height
component of the position solution.
-
TDOP
- Time DOP; indicates the quality of the time
solution.
-
UTC Date & Time - The current date, time and GPS week number,
typically derived from GPS measurements. Note that this is not local
time. The local time offset must be applied to get local time.
