Certain security and cybersecurity design details had been deferred to a security verification review that was not scheduled to finish until late summer/early fall 2015. Early January 25–28, 2016 design work on the interfaces with the lead platforms chosen by each of the services may not have been rigorous enough “to Hyatt Regency Monterey account for implementing those designs across various operating Monterey, California environments.” “The Undersecretary’s office also pointed out,” wrote GAO, “that the refinement of security countermeasures may result in ONE Registration Fee later design changes.” In addition to these points, the GAO highlighted a disagree- TWO Technical Meetings ment between the Army and the Directorate over whether the and a Commercial Exhibit MGUE design actually meets the Army's operational require- ments, including the Army’s assertion that the GPS Directorate unilaterally edited a key requirements document over the Army’s “significant objection.” The problem, which involves average maximum versus instantaneous power limits, could force the services to do additional development work to integrate the cards into their equipment.

A total of 10 more stations are under construction. The Russians have 28 satellites on orbit though two are in flight THE INSTITUTE OF NAVIGATION test and two are undergoing checks by the prime contractor. The program plans to orbit up 9 more satellites this year and next with the final number to be determined based on the need to replace existing spacecraft. The American GPS constellation has 31 satellites in operation with another nine on-orbit spares. The satellites are aging, how- ever, with one of the spacecraft close to 25 years old. The GPS Directorate is moving quickly to update the system launching six satellites in the last 19 months, the most intense launch schedule since 1993. Another launch is scheduled for the end of October and the last of the IIFs will be lofted in February of next year. At present 10 of the 31 satellites in the constellation are the newest IIF satellites, which transmit the new L5 civil signal. The new birds may be contributing to the continued improvement in accuracy which Col. Steven Whitney, director of the GPS Directorate, said reached a user range error of 39 centimeters on September 2. The Japanese Quasi-Zenith Satellite System (QZSS) is also planning for more satellites. A four-satellite constellation is to be complete in 2018 with two more satellites joining the current Michibiki spacecraft in quasi-zenith orbit and one satellite in GEO orbit. That GEO satellite will also be used to provide a satellite- based augmentation system or SBAS signal that will be available starting in the early 2020s, said Yoshiyuki Murai, executive direc- tor for promotion of QZSS utilization at the NEC Corp., which April 11-14, 2016 has a contract to support Japan’s QZS Services Inc. Mentioned as a possibility last year, the Japanese government Hyatt Regency Savannah has made a definitive decision to expand the planned initial constellation to seven satellites by 2023. To support their overall Savannah, Georgia service the Japanese will need to place monitoring stations outside ABSTRACTS DUE: OCTOBER 30, 2015 of Japan, Murai said in response to a question, although the place- www.ion.org/plans ment of those sites did not appear to be settled.
