Description
This function computes navigation course (bearing), navigated distance, time diference and navigation speed between GPS fixes in position data imported from an HAC file.
Usage
1
navigation.hac(pos)
Arguments
pos
geographic position data from an HAC file, as imported with position.hac.
Details
The bearing and navigated distance are computed with functions bearingRhumb and distVincentyEllipsoid from package geosphere. This function is intended to be called inside read.echogram, rather than being used directly.
Value
A data frame with seven variables:
time.cpu
date and time from the computer CPU during data acquisition.
lon
longitudes.
lat
latitudes.
bearing
navigation course between two consecutive GPS fixes.
navdist
navigated distance between two consecutive GPS fixes.
time.dif
time difference between two consecutive GPS fixes.
navspeed
navigation speed between two consecutive GPS fixes.

View source: R/navigation.hac.R
Description
This function computes navigation course (bearing), navigated distance, time diference and navigation speed between GPS fixes in position data imported from an HAC file.
Usage
1 | navigation.hac(pos)
|
Arguments
pos |
geographic position data from an HAC file, as imported with |
Details
The bearing and navigated distance are computed with functions bearingRhumb and distVincentyEllipsoid from package geosphere. This function is intended to be called inside read.echogram, rather than being used directly.
Value
A data frame with seven variables:
time.cpu |
date and time from the computer CPU during data acquisition. |
lon |
longitudes. |
lat |
latitudes. |
bearing |
navigation course between two consecutive GPS fixes. |
navdist |
navigated distance between two consecutive GPS fixes. |
time.dif |
time difference between two consecutive GPS fixes. |
navspeed |
navigation speed between two consecutive GPS fixes. |
