TD-3 is a digital
balloon theodolite which traces a pilot balloon in the sky,
and transfers elevation and azimuth data to a printer or a
computer at fixed intervals for obtaining information in the
upper atmosphere.
It digitalizes and displays electric signals from the elevation
and azimuth encoder.
It can also sample data at a preset measurement interval on
the basis of built-in real time clock and output sample data
with the time information from the RS232C terminal. |
