Stephen McAnally has passed away
Posted October 01, 2015

Stephen McAnallyCedar Rapids Happy trails to our native son, Stephen Lee McAnally of Colorado Springs, Colo., who died Tuesday, Sept. 22, 2015. Services are pending. Born in Cedar Rapids, Iowa, on Nov. 3, 1949, to Betty and Robert McAnally, he went on to become truly one of a kind. Steve graduted from Washington High School in 1967 and entered Loras College. After his dad's car accident in 1967, he left school to come home and support his mother and eight brothers and sisters. In 1969, Steve joined the U.S. Air Force and served through 1974. Stationed at ENT Air Force Base in Colorado Springs, he had found a new home there. You might say he was born again. His love for the outdoors drew him into engineering, where he founded and operated Shavano Land Survey. Steve was a true sportsman, enjoying and participating in many sports. He was a Rockies, Broncos and Hawkeye fan. His heart belonged to baseball though, and how fitting that his hero, Yogi Berra, and he would enter the pearly gates the same day. Steve's spirit lives on through his wife, Mary; his children, Jeremy, Patrick, Phillip and Allison; his mother, Betty Meis; brothers, Tom and Jim Meis; sisters, Susan Hippert, Julie McNeal, Kris Smith and Cindy Petersen; aunts, uncles, nieces, nephews and cousins, all who love him and will miss him very much. In honoring your well-lived life Steve, the highest compliment is also the simplest.Enter body here...

CORS Site in Pueblo under threat of decommission
Posted August 25, 2015

The Federal Register has issued a "Notice: Request for Public Comments" from the Coast Guard (USCG), the transportation Department (DOT), and the Corps of Engineers (USACE) dated 08/18/2015. The Nationwide Differential Global Positioning System (NDGPS) service augments GPS by providing increased accuracy and integrity using land-based reference stations to transmit correction messages over radiobeacon frequencies. The service was implemented through agreements between multiple Federal agencies including the USCG, DOT, and Army Corps of Engineers, as well as several states and scientific organizations, all cooperating to provide the combined national DGPS utility. However, a number of factors have contributed to declining use of NDGPS and, based on an assessment by the Department of Homeland Security, DOT, and USACE, DHS, DOT, and USACE are proposing to shutdown and decommission 62 DGPS sites, which will leave 22 operational sites available to users in coastal areas. This notice seeks public comments on the shutdown and decommissioning of a total of 62 DGPS sites. Termination of the NDGPS broadcast at these sites is planned to occur on January 15, 2016.You may view the Notice at See the Notice for details regarding submission of comments. Comments and related material must reach the Docket Management Facility on or before November 16, 2015.
