Onwards and Upwards - Radiometrix Lends Hand to U.S. Students
22, 2009 -- Wireless communication specialist Radiometrix has supplied two custom radio transceivers to
Idaho State University for its Research Involving Student Engineers (RISE) program. The London-based
company supplied the pair of customised UHX1 multi-channel radio transceivers tuned to a special VHF frequency
(147 MHz) with US distributor, Lemos International.
The program is sponsored by NASA and releases weather balloons with ceilings exceeding 25,000 meters. The
balloons have payloads made up of a camera box, an automatic position reporting system for tracking purposes,
and a flight computer. In addition, the balloons can carry various experiments from extremeophile bacteria
research to simple egg drop mechanisms.
Weight is a key concern to comply with Federal Aviation
Administration's 12 lb weight limit on these flights. "Finding a compact, lightweight radio solution was vital
to the continued success of the project", noted Professor Tim Frazier, the project's faculty sponsor.
Researchers have been looking at how to miniaturize the multi-channel tracking package, and the Radiometrix
module offered a way of achieving this. "Lemos and Radiometrix have worked with us to choose a suitable
transceiver and associated electronics for the project," explained Ben Estes, program member. "The UHX-1 module
from Radiometrix has enabled a transparent serial link between the control station and the flight computer in
the balloon once it is airborne.
This allows full communication between the balloon and the ground crew,"
Estes continued, "allowing them to operate vents, cut-down mechanisms, parachute deployment, and actuate any
other mechanisms needed" he concludes.
The full range of Radiometrix products are available in the USA
via the company's official distributor,
