Short Description:
------------------
A program to convert Latitude/Logitude coordinates to LORAN C
delays and vice versa. In addition, the program calculates head-
and distance from point "A" to point "B" with the location of the
points specified either as Lat/Lon or LORAN delays. It also per-
forms Time/Speed/Distance calculations and provides hard copy for
all functions. Registered users are provided with data files
covering all LORAN chains world-wide. An editor allows the add-
ition of new chains.
Long Description:
-----------------
There is an increasing need for software which will convert
Latitude/Longitude data to LORAN-C delay coordinates and
vice-versa for the purpose of adding LORAN-C data to the many
charts and maps, both land and marine which are published with-
out this information. In addition to the LORAN-Geographic
conversion, MARNAV also provides a means of calculating all
delays for a given geographic location thus allowing a shift to
another slave in the event of technical difficulty or as a means
of double checking a position.
All LORAN-C Chains for which data is currently available
are included for registered users. The data used is based on
information from the UNITED STATES COAST GUARD, Department of
Transportation as published in COMDTINST-M16562.3 (Old CG-462).
In addition to LORAN-C Geographic conversions, MARNAV also
provides the ability to navigate from one pair of LORAN-C
delays to another pair within the same chain. In cruise
planning, waypoint data is generally listed during the planning
stage and since these data are already available it is conve-
nient to use them for calculating heading and distance
information. In addition it is also possible to calculate head-
ing and distance information from Latitude/Longitude data over a
rhumb line course. These programs do not parallel programs
available within typical LORAN-C units available today since
those computer navigation features calculate from measured
delays at present position.
Since the Navigation solutions are available it only seemed
logical to include a Time/Speed/Distance function. The simplest
data entry scheme appeared to be the query for each entry with a
calculated result for the one not entered.
Hard copy is optionally available for all calculations to
facilitate cruise and trip planning. The GRI data base may be
edited and delay correction factors may be entered. New GRI data
can also be entered.
Registration Information:
__________________________
Registration fee is Thirty Five Dollars. You will receive the
version of the program as well as discounts on other programs
in development on this and related subjects. In addition, you
will receive data files for all LORAN chains in the world.
