GAO Report: More Delays, Cost Increases for OCX, GPS III

New delays and higher costs should be expected for both the GPS III satellite program and GPS-OCX, the new GPS ground system, federal watchdogs warned in a new report.

The Government Accountability Office (GAO) said both programs are in the process of rebaselining, that is, resetting their estimated schedules and costs. In the case of the Next Generation Operational Control System (GPS OCX), which is essential for full operation of the new GPS III satellites, the changes could be significant.

Expanding EGNOS Horizons

The European Geostationary Navigation Overlay Service (EGNOS) has a European regional coverage that could be extended quite easily to areas adjacent to the European Union. Backed by the European Commission, a public/private consortium is operating programs of technical assistance to prepare nations in the Mediterranean region to adopt and exploit European GNSS services in their priority market segments, namely aviation and road freight transport/logistics.

Galileo Upgrade Will Cause Temporary Decline in Service

Galileo’s operation controllers will temporarily stop updating satellite orbital positions in the system’s navigation messages beginning near the end of this month in order to help implement upgrades in the ground mission segment, the European Space Agency (ESA) announced today (January 19, 2015).

Although the Galileo satellites will continue to transmit navigation signals, the generation and uplink of updated navigation messages will be interrupted during the last week of January for about five weeks.

First GPS III Launch Slips to FY17

The launch of the first GPS III satellite could slip to as late as March 2017, further delaying a modernization program that already has been pushed back repeatedly by budget cuts and technical problems.

“The first GPS III launch is tentatively considered for the first half of FY17, based on booster availability and Air Force launch priorities,” a spokesman for the Space and Missile Systems Center told Inside GNSS.
