Lockheed Martin announced that it has delivered the first modernized Global Positioning System (GPS) satellite to Cape Canaveral Air Force Station, FL, where it will be readied for a May launch. The satellite, designated GPS IIR-M1, is the most technically advanced GPS satellite ever developed and will provide significantly improved navigation performance for US military and civilian users worldwide. This satellite is the first in a series of eight GPS IIR satellites that Lockheed Martin is modernizing for its customer at the Navstar GPS Joint Program Office, Space and Missile Systems Center, Los Angeles Air Force Base, CA. “Delivery of the first modernized IIR satellite is a significant milestone in the GPS mission,” said Dave Podlesney, Lockheed Martin GPS program director. The current constellation of 30 GPS spacecraft includes 12 fully operational Block IIR satellites, which were developed to improve global coverage and increase the overall performance of the global positioning system. The modernized series, designated GPS IIR-M, will offer a variety of enhanced features for users of the navigation system, such as:
The flexible design of the modernized spacecraft will enable GPS users to experience these benefits after launch and operational turnover of the satellite. The Global Positioning System enables properly equipped users to determine precise time and velocity and worldwide latitude, longitude and altitude to within a few meters. Air Force Space Command’s 2nd Space Squadron (2SOPS), based at Schriever Air Force Base, CO, manages and operates the GPS constellation for both military and civil users. The modern navigation payload is being built by ITT Industries in Clifton, NJ. The satellite upgrades, along with final assembly, integration and tests are being performed at Lockheed Martin facilities in Valley Forge, PA.
