Ballistic trajectory corrections
Failing to adjust for meteorological
conditions accounts for about two thirds of inaccuracy. Studies conclude that the largest improvements in
accuracy can be achieved using meteorological corrections. During the past 25
years hundreds of Vaisala sounding systems are used world wide by defence
forces.
Vaisala provides two different technology
sounding systems: 1680 MHz band RDF for tracking and wind finding, and 403 MHz
band systems using GPS for positioning and wind finding. Both type of systems
are mobile and quick to be deployed. They provide meteorological data in
standard NATO and WMO message formats using either serial communication lines
or TCP/IP FTP server. For fire control units’ ballistic corrections,
Vaisala’s upper air weather observation systems are ideal.
