Global Navigation Satellite Systems Engineering, Policy, and Design
In the beginning, GPS was envisioned as a military program. A sign on the wall in the Joint Program Office where the systemcame into being during the early 1970s read: “The mission of this Program Office is to:
A Department of Homeland (DHS)-chartered May 2021 report concludes that PNT threat and resilience concerns are not as dire as some have made them out to be, and that funds for backup could be spent elsewhere. Why this runs counter to other recent government reports is not clear, nor is the fallout from this divergence of Congressionally mandated views. The Department of Transportation has distanced itself a bit from this report by the RAND Corporation—and even its issuer, the DHS, seems to have done so.
BAE Systems selected Spirent Federal Systems to provide a controlled reception-pattern antenna (CRPA) test system to support M-Code military GPS technology development.

NASA has awarded a contract to the University of Michigan for the Cyclone Global Navigation Satellite System (CYGNSS) for mission operations and closeout. A constellation of eight microsatellites, the system can view storms more frequently and in a way traditional satellites are unable to, increasing scientists’ ability to understand and predict hurricanes. The total value of the contract is approximately $39 million. The CYGNSS Science Operations Center is located at the University of Michigan.
