Location, Location
Off course… Reported missing… Overdue… These are
chilling words. The lives of those in distress, and of those
who risk their lives to save them, depend on the accurate and
timely determination of the distress location. Detection and

location determination of Cospas-Sarsat alerts are the
primary functions of the EMS LEOLUT 600.

The LEOLUT 600 is based on over 20 years of EMS
experience in the design and evolution of LEOLUT
technology. The LEOLUT 600 uses industry standard
components to provide mission critical reliability, and
scalability to ensure years of continued service.

A fully automated high performance satellite earth station, the
LEOLUT 600 monitors, receives and processes distress
signals relayed from COSPAS-SARSAT satellites. After each satellite
pass, it processes the signals from emergency beacons to update
location information. The LEOLUT 600 monitors time and frequency data
to detect and locate the active beacon, and then sends location co-
ordinates and other pertinent information to the Mission Control Center fo
r
analysis and distribution to SAR resources. A key function of the EMS
LEOLUT 600 is its ability to internally maintain satellite orbit data.

EMS LEOLUTs are the only LUTs in the world today that can perform
combined LEO/GEO processing as defined in the COSPAS-SARSAT
specifications. LEO/GEO processing can improve the determined beacon
location accuracy by using data received from a GEOLUT. In some
instances, this combined processing can provide beacon location
solutions when LEOLUT processing alone cannot.

The EMS LEOLUT 600 and GEOLUT 600 systems work together to
provide a comprehensive SAR system. With their advanced combined
LEO/GEO processing functionality, these EMS systems provide SAR

users with response capabilities unmatched by any other system provider.

The LEOLUT 600 is a fully-
automated high
performance satellite
ground station that receives
and processes distress alerts
from SARSAT and COSPAS
satellites, determines the
beacon location, and
forwards data to search and
rescue forces.

The LEOLUT 600 builds upon the qualit
y
standards of earlier models while
incorporating the most current technology.
A
powerful industry standard computer and
custom software provides the advanced
digital signal processing required for complex
SAR data. Its modular hardware and
software architecture facilitates scalabilit
y
and ease of enhancements. Proven
reliability, a reduced parts count, and use o
f
Commercial Off-The-Shelf components are

examples of EMS’ commitment to keep the
LEOLUT 600 at the forefront of LUT
technology.

The EMS LEOLUT 600 is the most feature-
rich, comprehensive LEOLUT available
today. Based on the proven ATLUT
technology, which demonstrated a 99.9%
reliability factor, the LEOLUT 600 provides
maximum performance and dependability
that is critical for rescue operations.

The LEOLUT 600 can function alone or in a
dual LUT configuration. In a dual LEOLUT
configuration, two LEOLUT 600s are used to
optimize satellite coverage of a region. The
LEOLUTs coordinate their pass schedules
to ensure that the maximum number o
f
satellites are tracked. This configuration has
proven itself in providing fast ambiguity
resolution in distress situations, especiall
y
near the equator where fewer satellite may
be seen.
Many LEOLUT 600 systems can be grouped
into a network to provide coordinated
coverage of a larger national region.
