Projects

Here are a few of the projects on which EMS has recently worked or is currently working:
 

Measuring 88' antenna

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. 

SMA  assembly

Submillimeter Array (SMA) radio telescope for the Smithsonian Astrophysical Observatory (Mauna Kea, Hawaii): EMS designed the reflector assembly tooling and wrote the surface panel alignment software. When installed, the 8 reflectors that comprise the array will operate up to 860 GHz. 

Iridium compact range reflector

Compact Antenna Test Range for the Raytheon Iridium Program (Waltham, Massachusetts): EMS designed and aligned the reflector, and also oversaw the installation on-site.

GBR-P antenna

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.

Learn more about the alignment work in a Leica article.

 

NASA compact range reflector

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 installation.

Link to Have Stare Picture

Have 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 Vardö, 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.  Click here for a photo of the installed reflector.

...and here's a few links to other EMS projects: radio telescopes in Sweden, Korea and Japan; photo #1 and #2 of a compact range at Ft. Huachuca, Arizona; images of current measurement and product development work.
