receivers |
Data frame of all receivers with station names and positions. |
bearings |
Data frame produced by doa(). |
only_one |
Whether a location should be estimated based on signal strength if only one bearing is available in a time slot. |
time_error_inter_station |
Accepted time discrepancy between station clocks in seconds. Used in timematch_inter() |
angles_allowed |
Vector of lower and upper limits for angles between bearings. |
tri_option |
What to do if more than two bearings per time slot are available: "two_strongest" - just consider the two bearings with the strongest signal, "centroid" - calculate a centroid of all intersection points |
tm_method |
Which method of time matching to use: "tm" - time slots, "spline" - spline smoothing See |
spar |
Smoothing factor for the spline to be used with |
progress |
Whether this call is wrapped in a |
Data frame containing triangulated UTM coordinates.
