GAO: OCX Problems Threaten GPS Constellation

A new federal watchdog report released yesterday (September 9, 2015) questions the outlook for the still-developing GPS ground control system saying the Pentagon may not fully understand the true cause of ongoing problems in a program where further delays “may likely pose significant risks to sustaining the GPS constellation and delivering GPS capability.”

GLONASS for Precise Navigation in Space

Figures and Tables

The current stage of GLONASS evolution is aimed at meeting future user requirements of which the most important is the improved accuracy of positioning.

During the implementation of the GLONASS Space Segment Modernization Program (2012–2015), the GLONASS team is facing the situation in which it is not feasible to launch new navigation satellites because the existing constellation is comprised of GLONASS-M satellites operating beyond their guaranteed design lifetime. Nine more GLONASS-M satellites are in ground storage.

New Fiscal Year Begins with Unfinished GPS Business

New Fiscal Year Begins with Unfinished GPS Business

Most folks look to a new year as an opportunity for fresh starts and new projects. For the GPS community, however, the October 1 start of the 2016 federal fiscal year (FY16) will likely be more about the hangover — that is, the issues that are hanging over into the next 12 months, unresolved.

At the top of that list of unfinished business are two system decisions: a go/no-go determination on whether the United States will build eLoran as the U.S. backup to GPS and deciding whether or not to choose a new contractor for the GPS III program.

LightSquared Launches New GPS Receiver Tests

LightSquared’s proposed GPS receiver tests are relying on an outdated standard of GPS accuracy, a choice some experts suggest is a maneuver aimed at dramatically lowering the bar the would-be wireless broadband company has to meet for showing noninterference to GPS signals.

Appropriations Impasse Could Stall U.S. GPS Programs

Appropriations Impasse Could Stall U.S. GPS Programs

The federal government is once again approaching the end of its fiscal year without the appropriations necessary to keep the doors open come October 1 — a reality that could undermine GPS modernization and related programs.

Congress, now in the midst of its August recess, will have just 12 days to sort things out when members return after Labor Day. Under the best of circumstances, lawmakers would almost certainly need to pass a continuing resolution (CR) to extend current spending levels and buy themselves time to hammer out budgetary deals.

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

Officials Delay First GNSS Authorization Request; Light-Squared Tries to Leverage Issue

The U.S. stance on satellite navigation has long supported international cooperation and a degree of interoperability. In 2010 the Obama administration even adopted a space policy that said foreign satnav services could be used “to augment and strengthen the resiliency of GPS.”

That was easier in the abstract, however, when the only fully functional GNSS was GPS. Now, with other GNSS services coming online, American officials want to think things through again.

10th GPS IIF Satellite on Its Way to Orbit

The U.S. Air Force and its mission partners successfully launched the 10th Boeing-built GPS IIF satellite aboard a United Launch Alliance Atlas V from Cape Canaveral Air Force Stations today (July 15, 2015).

The spacecraft is destined for plane C/slot 3 of the GPS constellation

The launch almost coincided with Friday’s 20th anniversary of the declaration of full operational capability (FOC) for the GPS constellation, which occurred on July 17, 1995.

Just two GPS IIF satellites remain to be launched — Atlas V rockets will be used to launch both.
