A dramatic increase over the next five years to roughly 100 GNSS satellites in the skies over Asia and Oceania makes that region the fastest growing area in GNSS. The Multi-GNSS Asia (MGA) initiative, a cooperative international demonstration campaign, seeks to take full advantage of this scientific and technical windfall, gaining early experience with the new signals and services of multi-constellation GNSS.
Experimenting with GPS on Board High-Altitude BalloonsIn this month’s column, we look at how a team of Dutch and Japanese researchers is using GPS to determine the attitude of a payload launched from a high-altitude balloon.
The Japan Aerospace Exploration Agency (JAXA) has controlled the orbit of the first quasi-zenith satellite system (QZSS) satellite, Michibiki. JAXA inserted Michibiki into the quasi-zenith orbit from the drift orbit starting on September 21 (Japan Standard Time, JST). The final orbit control operation was performed for about 50 seconds from 6:28 a.m. on September 27 (JST).
