The legal and privacy issues surrounding GPS investigations have come to the forefront around the globe in recent years. Recent court rulings in both Japan and the United States provide insights into the future. Here we summarize and examine a decision by the Japanese Supreme Court and relevant lower court’s decisions, as well compare the Japan decision and the mosaic theory from an earlier U.S. court decision.

Some good news has been reported and some nice progress has been made by the Indian Space Research Organization (ISRO) this year.
The successful launch of the PSLV-C41 rocket carrying India’s eighth navigation satellite IRNSS-1I from Sriharikota put smiles back on the faces of scientists of the ISRO in April amid tough times as the space agency was struggling to restore the snapped link with its recently launched communication satellite Gsat-6A.

An independent technical review ordered by the federal government’s top GPS policy body found that there is sufficient data to assess the risk of using frequencies near the GPS band for a ground-based communications network. Existing test results can also be used to set power limits for other similarly located projects, said a panel of technical specialists. Two tests sponsored by Ligado Networks, however, did not meet minimum criteria for inclusion, the panel said.
