88 foot diameter Ka-band earth terminal
(classified location): EMS used a total station
theodolite system to measure the gravity
deformations of the reflector assembly and aligned
the reflector surface.
Array (SMA) radio telescope for the Smithsonian
Astrophysical Observatory (Mauna Kea, Hawaii):
EMS designed the reflector
assembly tooling and wrote the surface
software. When installed, the 8 reflectors that
comprise the array will operate up to 860
Compact Antenna Test Range for the Raytheon
Iridium Program (Waltham, Massachusetts):
EMS designed and aligned the reflector, and
also oversaw the installation on-site.

Phased Array Radar for Raytheon GBR-P (Ground
Based Radar - Prototype) Program (Kwajalein,
Marshall Islands): EMS supervised the installation
and alignment of the
array plates which comprise the 14-meter diameter
flat surface shown in the photograph. The radar is
part of the National Missile Defense system.

Large Compact Range Reflector for
NASA-Langley AFB (Hampton, Virginia): EMS
designed the 27 foot square rolled-edge,
low-frequency reflector and supervised the on-site
to Have Stare Picture
Stare Radar for Raytheon (Vandenberg AFB,
California): EMS measured and aligned the
Cassegrain optics components of this 88 foot
diameter radar. The deformations of the primary
reflector, subreflector and feed as functions of
elevation angle were measured. In 1999 the radar
was be moved to
Norway. In July, '00 EMS returned to
Vardö to complete the alignment work.
Compact Range Reflector: EMS designed a
21 foot rolled-edge compact range
reflector for General
Electric's jet aircraft plant in Evandale,
Ohio. The facility tests RCS (radar)
characteristics of jet engine components.
