What Is Achievable with the Current Compass Constellation?

November 1, 2012By

Data from a tracking network with 12 stations in China, the Pacific region, Europe, and Africa demonstrates the capacity of Compass with a constellation comprising four geostationary Earth-orbit (GEO) satellites and five inclined geosynchronous orbit (IGSO) satellites in operation. The regional system will be completed around the end of 2012 with a constellation of five GEOs, five IGSOs, and four... read more

Innovation: Getting Along

November 1, 2012By

Collaborative Navigation in Transitional Environments
In this month’s article, a team of researchers at The Ohio State University discusses a system under development for collaborative navigation in transitional environments — environments in which GPS alone is insufficient for continuous and accurate navigation. Their prototype system involves a land-based deployment vehicle and a human operator carrying a personal navigator sensor assembly, which initially navigate together before the personal navigator transitions to an indoor environment. This system will have multiple applications including helping first responders to emergencies. Read on. read more

The System: Galileo, Compass, GPS Launches All Succeed

November 1, 2012By

October 12: A Soyuz launcher carrying two Galileo In-Orbit Validation (IOV) satellites deployed its twins into orbit within 4 hours after take-off, at close to 23 200 km altitude. They join two earlier IOV spacecraft launched in October 2011. Once all four are operational in space, they will provide the minimum number of satellites required for navigational fixes — enabling... read more
