Big government’s inefficiency comes in a variety of flavors, and this one could hit your dashboards as early as next year. According to a report from the Government Accountability Office (GAO), the U.S.’ Global Positioning System (GPS) could begin to experience black-outs and general failures next year due to the delays, mismanagement and underinvestment by the U.S. Air force. 

The report’s summary offers the following: The Global Positioning System (GPS), which provides position, navigation, and timing data to users worldwide, has become essential to U.S. national security and a key tool in an expanding array of public service and commercial applications at home and abroad. The United States provides GPS data free of charge. The Air Force, which is responsible for GPS acquisition, is in the process of modernizing GPS. In light of the importance of GPS, the modernization effort, and international efforts to develop new systems, GAO was asked to undertake a broad review of GPS. Specifically, GAO assessed progress in (1) acquiring GPS satellites, (2) acquiring the ground control and user equipment necessary to leverage GPS satellite capabilities, and evaluated (3) coordination among federal agencies and other organizations to ensure GPS missions can be accomplished. To carry out this assessment, GAO’s efforts included reviewing and analyzing program documentation, conducting its own analysis of Air Force satellite data, and interviewing key officials.

It is uncertain whether the Air Force will be able to acquire new satellites in time to maintain current GPS service without interruption. If not, some military operations and some civilian users could be adversely affected. (1) In recent years, the Air Force has struggled to successfully build GPS satellites within cost and schedule goals; it encountered significant technical problems that still threaten its delivery schedule; and it struggled with a different contractor. As a result, the current IIF satellite program has overrun its original cost estimate by about $870 million and the launch of its first satellite has been delayed to November 2009–almost 3 years late. (2) Further, while the Air Force is structuring the new GPS IIIA program to prevent mistakes made on the IIF program, the Air Force is aiming to deploy the next generation of GPS satellites 3 years faster than the IIF satellites. GAO’s analysis found that this schedule is optimistic, given the program’s late start, past trends in space acquisitions, and challenges facing the new contractor. Of particular concern is leadership for GPS acquisition, as GAO and other studies have found the lack of a single point of authority for space programs and frequent turnover in program managers have hampered requirements setting, funding stability, and resource allocation. (3) If the Air Force does not meet its schedule goals for development of GPS IIIA satellites, there will be an increased likelihood that in 2010, as old satellites begin to fail, the overall GPS constellation will fall below the number of satellites required to provide the level of GPS service that the U.S. government commits to. Such a gap in capability could have wide-ranging impacts on all GPS users, though there are measures the Air Force and others can take to plan for and minimize these impacts. In addition to risks facing the acquisition of new GPS satellites, the Air Force has not been fully successful in synchronizing the acquisition and development of the next generation of GPS satellites with the ground control and user equipment, thereby delaying the ability of military users to fully utilize new GPS satellite capabilities. Diffuse leadership has been a contributing factor, given that there is no single authority responsible for synchronizing all procurements and fielding related to GPS, and funding has been diverted from ground programs to pay for problems in the space segment. DOD and others involved in ensuring GPS can serve communities beyond the military have taken prudent steps to manage requirements and coordinate among the many organizations involved with GPS. However, GAO identified challenges in the areas of ensuring civilian requirements can be met and ensuring GPS compatibility with other new, potentially competing global space-based positioning, navigation, and timing systems.

OnStar getting upgrade for pinpoint accuracy in emergencies

In the event of a crash, vehicle sensors gather up information and connects an OnStar adviser to a vehicle. OnStar can then contact emergency services and provide information regarding the severity of the crash, with information about airbags deployed and type of impact. 

In the past, OnStar advisers would have to give emergency services a detailed description of the location of the accident.

Subscribers to the telematics system will benefit from new technology that will enable OnStar to electronically transmit precise longitude and longitude coordinates directly to the 911 center. Where available, the Automatic Location Identification (ALI) data display will show the authorities exactly where you’re located, with almost zero opportunity for error.

The presser had the following info: With this newest OnStar enhancement, 911 centers can automatically receive specific vehicle location information (longitude and latitude) in the 911 Automatic Location Identification (ALI) data display which may interface with a sophisticated mapping system used in many jurisdictions to expedite locating emergency victims. 

“In an emergency, accurate location is the most important piece of information to ensure that help arrives promptly at the scene,” said Cathy McCormick, Emergency and Security Service Line manager, OnStar.

In addition to providing location information, OnStar advisors continue to play an important role in providing critical crash and other emergency-related information directly to dispatchers to help them determine the most appropriate response. 

“The Association of Public Safety Communications Officials has worked with telematics providers since their inception to use the latest technology to assist public safety in saving lives,” said Chris Fischer, president, APCO International. “This technology interfaces with the systems many of our centers have in place already to expedite response.”

With OnStar’s Priority Access program, many PSAPs already receive OnStar emergency calls through an existing 911 trunk line. By routing verified emergency calls to 911 trunk lines, dispatchers will not only receive OnStar calls more quickly, they will also receive important call-related data, including OnStar’s PSAP-only callback number. 

Sentience Intelligent Cruise Control Lets You Forget the Pedals Altogether While Driving

Driving would be way more fun if we didn’t have to worry about the whole gas and brake thing, right? Sentience understands this, and their intelligent cruise control means you can finally forget about it.

How it works

 

Based on route information – which could eventually be integrated with a commercial navigation system – the Sentience vehicle will calculate and follow an optimal driving strategy. Its control system adjusts vehicle speed, acceleration and deceleration via its adaptive cruise control and regenerative braking. Using GPS and mapping data it takes into account the speed limits, traffic conditions, the road’s gradient and features including bends and even speed bumps, as well as less predictable road features including roundabouts, to determine the most efficient possible route.

It’s also keyed in to traffic light timing, so it will automatically start decelerating if it knows the green light you’re approaching is about to turn red. The driver simply keys in a destination, and steers the car without a foot on either pedal, letting the car make the decisions on acceleration and braking. Of course, you’d want to keep your foot close to the brakes to over-ride the system in case of an emergency situation.

The Sentience system also concentrates on getting the most out of hybrid drive systems, by optimizing the regenerative braking strategy for the batteries and increasing the availability of electric-only drive mode where possible.

 

. Sentience will analyze the best route to get you to your destination, and then will handle all the acceleration and braking for the trip. Using GPS and mapping data, It recognizes roundabouts, speed bumps, corners and even speed limits. Sentience will know when a light is about to turn red and slow down accordingly.
