Facilities and Local Area:

 

AntDevCo operates out of a 2100 square foot office/warehouse facility in Las Cruces, New Mexico.  We are close to the New Mexico State University with its Physical Science Laboratory antenna test facilities, machine shops, and highly qualified professors and scientists.  There are machine shops in the Las Cruces area with long experiences in aerospace products due to the proximity of White Sands Missile Range, NASA White Sands Test Facility, NASA TDRSS ground stations, and the soon-to-be-opened New Mexico Space Port.  The El Paso metropolitan area, with its international airport and a population of over 1 million people, is only 50 minutes away.  See ADC-0512012131 R4 Corporate data sheet for additional information.

 

History:

 

AntDevCo is New Mexico Sub-Chapter S Corporation formed in June of 2005 by Dr. Bruce Blevins and Mr. Thomas Greenling.  We are a spin-off from the Physical Science Laboratory at New Mexico State University.  As such, AntDevCo is able to use and improve the designs for spacecraft antennas developed by PSL. The two principals of AntDevCo have an aggregate experience of more than 40 years of antenna design, test, and manufacture.  Dr. Blevins has designed antennas for experimental astrophysics receivers, radars, and many small spacecraft and missiles.  Thomas Greenling began his antenna career with the repair of submarine antennas while in the Navy and has also designed numerous antennas for spacecraft and missiles.  Dr. Blevins owned and operated his own company, (Tesota Products Antenna Division - TPAD) in the 90’s and started his production of antennas for small spacecraft at that time.  Blevins and Greenling then worked together at the Electromagnetics group at PSL from 1997 through 2005 on many antenna programs for manufacturing and test.  We have personally been the leaders in the development of the low gain antennas for the TERRIERS, HETE, THEMIS, MIGHTYSAT, ALEXIS (Blackbeard), GENESIS, STARDUST, ROADRUNNER, ST-5, and HESSI spacecrafts – to name a few.  We designed the antenna for the General Dynamics Viceroy spacecraft GPS receiver – flown on many spacecraft.   This PSL experience, our full commitment to continuing the quality practices developed at PSL, and the detailed design information available to us from PSL establishes AntDevCo flight heritage for our spacecraft products.

 

We have also been the design engineers for a number of sounding rocket, ballistic missiles, and ballistic missile target vehicle antennas as subcontractors for BMD and other programs.  For example, Dr. Blevins led the PSL effort to develop and manufacture antennas for the MOD-7 wafer used in the sustaining flight tests of the Minuteman III missile.  We have also designed and developed a number of antenna hats (couplers) for spacecraft and missile antenna systems.
