- Location of a Signal
LOAS features and functions :
98, NT, 2000, XP, 2003 Server
Centroids, MLE, Huber, Andrews
- Create a lookup
list from any field to reduce typing.
- Import file types
include txt, dbf, db, mdb (via visual SQL),
xls, shp², dxf.
- Open, plot, and
analyze more than one bearing set at the same time using the GIS user
- Filter data with
simple commands or build complex visual queries from complex multi-table
databases (i.e. Access).
- Process all data
at once or a selected subset of the data.
- Process 2 or more
- Create error polygons
with biangulations, and error ellipses from bearing sets with more than
- Select error ellipse
confidence, maximum size, area units, and calculation method.
- Output options
include location estimates, interbearing angles, location distances,
error polygon/ellipse size, ellipse parameters, actual signal location
parameters (if actual locations are known during telemetry tests), etc.
- Automatic fallback
methods if MLE fails.
- Create new radio
telemetry data files. LOAS has no predetermined field name requirements
so you can name your fields what ever you wish (there is a 10 character
limit in Dbase files, but not for Paradox, Access, Excel, or text files)
- Enter or edit
data directly in the embedded
- Add user defined
fields to the result sheet and export file.
- Export or copy
and paste location results to an export file or to other software.
- Select what fields
- Export error ellipse
to a GIS compatible file (e.g. shape file).
- Import GIS vector
maps of your study site as background coverages².
- Use the GIS interface
to add or move receiver locations with the mouse.
- Has a set of simulation
functions for testing radio telemetry system parameters.
- And of course,
is a dBASE record limit for Widows 9x and NT, and we have never come
close to finding out if this is true and will be more limited by your
available RAM. Let us know if you reach an upper limit.
