Radiosondes are carried into the atmosphere by weather balloons.
While ascending they measure a combination of temperature, humidity,
barometric pressure, ozone, and wind velocity and radio the data
to a ground system for processing. They are used around the world
to gather data for weather predicting.
Sippican Mark II
The Mark II microsondes represent the state-of-the-art in
radiosonde design. Compatible with the W-9000 Meteorological System,
these radiosondes are designed for low cost, automatic upper air
soundings. The lightweight sonde facilitates one-man launch and
allows the use of a smaller balloon, thus reducing operating costs.
All Mark II microsondes measure pressure, temperature and relative
Sippican Mark II GPS
The Mark II GPS microsondes is designed to conduct a full
synoptic sounding to balloon burst using data generated from meteorological
sensors and the GPS satellite network. A full code correlating,
all in view GPS receiver and antenna are included in each Mark II
GPS microsonde. To ensure maximum reliability, the GPS receiver
can process signals form all visible satellites and is integrated
into the radiosonde electronics.
