DEGREANE HORIZON came about by the
transformation of the Electronics Department
of Ets DEGREANE, founded in 1926, into
an individual incorporated company whose
single stockholder is the VINCI Group. DEGREANE HORIZON is in 3 sectors connected
to electronics: • Defense since 1960 • Energy since 1973 • Meteorological Observation since 1984
Thanks to over 25 years of experience,
DH has been a global leader in the fields
of environmental measurement and engineering.
Several jobs to be found in our company:
• Everything linked to aeronautical meteorology
and to acquisition networks used
by meteorological services throughout
the world.
• Acquisition and transmission of sensitive
data: conception and making of aero
naval buoys, very low frequency operational
sonar emitters, underwater listening
polygons, and the development and
Maintenance in Operational Conditions of
surveillance radar.
• Transmission of warning signals which
use several communication networks:
telephone, radio and internet: alarm systems
and the protection of telecommunication
facilities against a surge in voltage.
Whatever your field of activity, DEGREANE
HORIZON puts all its know-how at your
disposal so as to meet YOUR own specific
need.
OUR VALUES : To be professional, to be
reliable and to listen.
To keep our customers satisfied and to
have the quality of our work acknowledged
remain our greatest motivation.
The “Bureau Veritas Corporation” has deemed
our quality management consistent to
the NF EN ISO 9001:2000 standards.
The environment, a necessity : A large range of skills ...
Major National Meteorological Services such as Météo France have
been using our products since 1985 to equip their synoptic and climatological
networks (the MIRIA, AURIA and XARIA series of stations). SIOMA : A leader in the world of airport meteorology
for airport safety
These days air safety is a major preoccupation for everybody
concerned in air transport. Accordingly aeronautical meteorology
is a critical component as much for the safety and well-being of
passengers as for the economic planning of airport operators.

SIOMA (Integrated Runway Meteorological Observation Systems) are
installed on over 300 airports. Products and services offered meet
the requirements of those who are responsible for improving the
environment, assuring transportation safety, and safeguarding life
and property.
SIOMA, conceived in 1990, is characterized by having been developed
in close cooperation between DEGREANE HORIZON, the Civil
Aviation authorities, METEO FRANCE and the Service Users.
SIOMA is designed for all categories of airports from small VFR
aerodromes right up to category III C major international airports;
it is an open system, modular and upgradeable complying with the
latest standards and recommendations of the WMO and ICAO.
It allows in particular for the rapid extension of sensor configurations
(wind profiler, meteorological radar…) or for system architecture
(ATIS, AMSS ...) based on technological needs development or
new operational needs of operators (new runways, change in airport
category...).
SIOMA consists essentially of five sub-functional elements developed
by DEGREANE HORIZON:
• AEROVIEW: Set of PC-type visualization stations for the comprehensive
display of meteorological data and messages.
• Runway equipment:
Meteorological sensors sited at runway midpoint, thresholds and
met garden including:
- TR 30 : The Transmissometer TR30 is a visibility sensor designed for aeronautical purposes.
- TL 320: This Laser-Ceilometer is a cloud height sensor mainly
used at airports to provide the altitude of the cloud bases (up
to three layers) and cloud cover in octat.
- DF 320: Forward scatter sensor designed for visibility measurements and Present Weather in option.
- PCL 1300: Wind profiling radar which measures the vertical profile of the wind and detects wind shear conditions.
• CIBUS: Duplex digital communication network which ensures a
secured sensor data acquisition and transmission through hub
concentration with FSK modems or radio modem or optical fiber
with maximum efficiency and reliability.
• CAOBS: A central Workstation designed for acquisition, processing,
data storage and analysis, messages entry and coding production
of METAR and SYNOP standardized messages, distribution facilities
for the broadcast of meteorological information and based
on a fully redundant operational configuration PC-type computer
(normal/stand-by) running Windows.
• Display indicators: Set of panel mounted indicators INT300, DEOLIA92
or PC type used as back-up.
