International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / During engine and airfield performance testing it is often necessary to acquire weather data
at the airfield where the test is being conducted. The airborne data acquisition system
(DAS) acquires data associated with flight parameters. A separate system records airport
weather conditions. Many times the separate system is an Automated Terminal
Information Service (ATIS) or the ground crew relaying wind speed, wind direction and
temperature from a weather station. To improve this system, the weather station is
designed to acquire and store the data in memory. Utilizing a second DAS that is remote to
the airborne DAS poses several problems. First, it is undesirable to have many different
data acquisition systems from which to process data. The problem then develops into one
of integrating the ground weather DAS with the existing airborne DAS. Other problems of
system integrity, compatibility and FCC licensing exist. Complete system integration while
maintaining integrity and compatibility is overcome by controlling signal format, flow and
timing and is discussed in detail. Further discussion of the issue of transmission is
overcome by a technique called spread-spectrum and is used in accordance with FCC rules
and regulations.
