True. Actually it can be both. APRS was originally
Automatic Packet Reporting System. The APRS concept
was developed long before GPS became a viable
amateur radio device. APRS was designed to facilitate
immediate and efficient transfer of digital data
between EVERYONE at an event or situation without
the need for the cumberson one-to-one packet-ACK
system currently in use in the 1980's.
APRS was designed to update everyone (N stations)
from ONE packet, instead of 2 * N which was standard
packet at the time. When GPS became a product for the
agverage HAM below $500 in the early 90's, I began to
let "P" also stand for POSITION.
I wish I hadn't. Now too many people see APRS
as just a map based Position tracking system and ignore
its features for everything else it was designed to do.
