COMMERCL.txt 6.3c COMMERCIAL VERSIONS OF APRS
COPYRIGHT 1992,93,94,95: The APRS formats are provided to all radio amateurs
for use in the amateur radio service. Anyone is encouraged to apply the
APRS formats in the TRANSMISSION of position, weather, and status packets.
However, the author reserves the ownership of these protocols for exclusive
commercial application and for all reception and plotting applications. Other
software engineers desiring to include APRS RECEPTION in their software
for sale within or outside of the amateur community will require a license
from the author. (very reasonably priced)
COMMERCIAL VERSIONS OF APRS ARE AVAILABLE and we can engineer specific
needs and applications. Pricing is under $200 for the first dispatcher
copy of APRS and a modest fee per stand-alone-tracking unit (Less than $25
each for 10). Additional copies of APRS for mobiles with PC's are
significantly less. Two significant enhancements for the dispatcher are
the OPTIONAL data interfaces so that APRS CAN SEND POSITS TO OTHER SOFTWARE
PACKAGES. Some of these other packages can zoom into the individual street
address and access other data bases for dispatching of fleet vehicles.
There are currently two such interfaces:
STREETS-ON-DISK:
This version writes all position reports to a file so that the other
program such as STREETS-ON-DISK, can display all object positions from that
file (you run both APRS and STREETS in a multi-tasking environment) The
STREETS program is sold by KLYNAS Engineering 805 583-1133 for about $225
but costs an additional $95 per county. The APRS interface to STREETS is
available from the author or PACCOMM at an introductory rate of $95. (Less
for amateur use). For more info contact Jim Carter, 2029 W. Hall Ave,
Santa Ana, CA 92704-5508 who has written a detail interface document.
DELOREM MAPING:
For other maping and data base programs that accept a NMEA input on a
serial port, APRS can output NMEA data via its second serial port to
simulate the output of a GPS. In this method, the APRS operator hooks any
object on the screen, and that position report is sent as a NMEA string over
to the other program that plots it on the map. In this scenario, APRS CAN
MAKE AN IDEAL FRONT END PACKET COMMUNICATIONS PROCESSOR FOR ANY OTHER DATA
BASE SYSTEM! PACCOMM suggested this approach so so far it is ONLY AVAILABLE
IN THE COMMERCIAL VERSION of ARPS distributed by PACCOMM.
APRS NMEA-0183 OUTPUT for OTHER COMPUTERS
APRS can output NMEA-0183 position data to other computers via a 4800 baud
data link. This option is useful if you have existing software that takes
NMEA-0183 position data (for a single unit) and you want to have the multi-
station capabilities of APRS. In this arrangement, APRS serves as a front
end processor to handle all APRS reporting and communications with multiple
stations and vehicles, while sending selected position reports over to
another computer running other Geo-location software.
APRS will output a GGA/VTG data format as if it was comming from a navigation
device. To select an object or station for output from APRS to the other
computer, simply use the cursor to HOOK the station. Each time you hook a
station, a NMEA-0183 report will be sent to the other computer via the
selected COMMport (usually 2 if your TNC is on COM1). If you want to track
a particular station continuously, simply hook the station on the P-List and
select TRACK function. Then, every position report from that station will
generate a NMEA report to the other computer. Also the +/- keys can be used
to quickly step through every station in APRS and transfer those posits over
to the other computer.
This pre-processor arrangement allows APRS to keep the big picture of where
everyone is on the big maps, and allows the normal APRS communications
capabilities between stations. All detail maping functions and database
applications are then run on a companion computer indpendent of APRS. The
communications operator simply hands off position reports to the database
operator whenever further detail on a unit is needed.
