FIGURE 1: System architectureCooperative vehicle safety applications should preferably have two-meter horizontal accuracy and six-meter vertical accuracy, all with a 95-percent availability. The solution must be developed to incorporate lower-cost sensor options, specifically, lower-cost inertial measurement units that can be generally characterized by the gyro drift of 100 degrees per hour and an accelerometer bias force of twice its mass times gravity (two milligals).

A GNSS signal simulator is mainly used to simulate GNSS signals transmitted by navigation satellites, propagated through the Earth’s atmosphere, and received by the receiver antenna. A simulator provides a convenient signal source for the test and validation of receiver function and performance and can also be used in GNSS experiments and studies of signal/data processing algorithms.

This is a 1993 photo of Walter, a German astronaut. He exemplifies the fearless approach to experimentation and the spirit of fun that we are looking for (DLR photo) [Updated June 30] Lucky you – you have three extra days to submit your GNSS application idea to the USA Challenge! The extended deadline is midnight Sunday (Europe) or 3 P.M. (Pacific time) on July 3.
Right now, some team is hard at work in a basement, an office, a dorm room or a lab. They are about to come up with a new, useful and commercially viable idea for a satellite navigation application or location based service.

MD 2011 trajectory (NASA)A schoolbus-sized asteroid grazed the Earth’s atmosphere around 1:00 P.M. (EDT) on June 27. It was 7,600 miles (12,300 km) away at its closest point, at which time it veered away across the South Atlantic Ocean.
It actually passed through the GPS constellation, alerting us to the vulnerability of our vital PNT space vehicles. We can now add asteroids to the the list of GNSS collision risks that already includes other satellites and space debris.

A new report by the American Meteorological Society (AMS) highlights the vulnerability of GPS-dependent critical infrastructures to disruptions caused by solar flares and other space weather events, and sets forth a series of recommendations for building robustness of the GPS service.
Entitled “Satellite Navigation & Space Weather: Understanding the Vulnerability & Building Resilience,” the report is based on a workshop organized by the AMS and held October 13–14, 2010 in Washington, D.C.
