U.S. Secretary of Defense Wants to Move Past GPS to MEMS-Based Navigation, PNT Experts Doubtful

Ashton Carter, the new U.S. Secretary of Defense has been making clear he supports moving past GPS to a disbursed network based on microelectromechanical systems or MEMS for position, navigation, and timing (PNT) information.

Carter, who was tapped to lead the Pentagon in February, appears to have first publically floated the idea a year ago, about six months after leaving the Department of Defense (DoD), where he had served most recently as deputy secretary of defense, a role that included cochairing the interdepartmental National Space-Based PNT Executive Committee.

LabSat SatGen GNSS Product Upgraded to Include BeiDou Signals

LabSat has launched a new version of its SatGen V3 software package that enables users to create scenarios for replay through any LabSat simulator and now includes BeiDou.

The software creates either user-generated or imported trajectory files for use with a LabSat GNSS simulator. The addition of the BeiDou B1 signals means that users can now test a device’s design and performance as if it were being used within the operating area of the Chinese GNSS constellation – which at present only provides full coverage in Asia.
