U.S. soldiers in Afghanistan are the first Army combat units to have access to GPS-guided 120-millimeter mortar cartridge capability — a rapidly fielded capability that has put precision guidance into a still-smaller military form factor.

The Program Executive Office (PEO) for Ammunition at Picatinny Arsenal, New Jersey, fielded the Accelerated Precision Mortar Initiative (APMI) cartridges to an infantry brigade combat team (IBCT) earlier this month, and is scheduled to field cartridges to the seven other IBCTs in Afghanistan within six months.

Obama: The Trifecta of Bad Timing on Technology Policies

Talk about your bad timing.

The outcome of the LightSquared/GPS controversy threatens to make President Obama a three-time loser in technology policy matters.

In March 2010, his administration proposed to open for drilling for oil and natural gas extensive expanses along the Atlantic coast, in the eastern Gulf of Mexico, and off the north coast of Alaska, many of those areas for the first time. Less than a month later the Deepwater Horizon oil well explosion unleashed the largest accidental marine oil spill in the history of the petroleum industry.

On March 2, ESSP (the European Satellite Services Provider) declared the safety-of-life (SoL) signal from the European Geostationary Navigation Overlay Service (EGNOS) officially available for use by aviation, following European Commission (EC) authorization to provide the service.

Similar to the U.S. Federal Aviation (FAA) Administration’s Wide Area Augmentation System (WAAS), EGNOS transmits real-time corrections to GPS signals over a large expanse of Europe and north Africa.
