The System: New LightSquared, Same Agenda, Billions at Stake

August 1, 2015By
This one’s in orbit now. Photo shows the nose cone containing GPS IIF-10 being lowered into position atop the launch vehicle, inside the rocket gantry at Cape Canaveral.

New LightSquared, Same Agenda, Billions at Stake In a late June filing with the Federal Communications Commission (FCC), Lightsquared asked the agency to reassign its spectrum licenses — which were at the root of a prolonged dispute in 2010 and 2011, and have never been fully utilized —  to a new licensee that would be wholly owned by a new... read more

Countering Ionospheric Disturbances Affecting GNSS in Brazil By Marcio Aquino After 27 months of intense research, the CALIBRA project ended successfully in February 2015, with the project team devising solutions to tackle the effects of perturbations typical of the Brazilian ionosphere on high-accuracy GNSS positioning. CALIBRA was funded by the European Union and the European GNSS Agency. Kicked off in 2012, CALIBRA first confirmed the vulnerability of... read more

Sentry in red, sensor locations in green.

By Jeffrey Coffed and Joseph Rolli, Harris The first and best step to combat the growing worldwide problem of GPS jamming is to pursue technologies that can detect and locate the jammers. Signal Sentry 1000 uses arrayed sensors to do just that: look out for jamming and track down its source once sensed. An array of sensors can be deployed... read more

A WINS for Warfighters

The current WINS form factor (left) sits beside a prototype for the future incarnation.

A new device is being developed to enable foot soldiers to find their exact location in GPS-denied situations. If satellite signals are blocked by heavy jungle canopy, or because of enemy interference, soldiers — and Headquarters — will still know where they are with the Warfighter Integrated Navigation System (WINS). read more

FIGURE 2. GRD-based image correspondence illustration as a function of 2-D relative navigation state.

We look at the development of a generalized vision-aided integrity monitor for precision relative navigation applications. A vision-aided integrity monitor could be extremely valuable in augmenting existing precision relative navigation systems, such as GPS, for many different safety-critical aerospace applications. read more
