GNSS Data Points and Factoids to Amuse and Inform

Twin launch trends, Galileo's Getaway, The iPhone cool factor, Typhoid's PNT and the Elusive ICD
1. Portland, Oregon and Los Angeles, California USA
Europe's and Russia's twin launch trend is catching on. Col. Bernard Gruber, USAF GPS Directorate, told CGSIC listeners in Portland, Oregon last September that GPS III satellites may head out in tandem as a cost-cutting measure. The modernized SVs start going up in 2014, and dual launches could begin as early as the sixth trip.
2. Kourou, French Guiana and Brussels, Belgium
Good thing the first two Galileo IOV satellites made it safely off the
planet on October 21 . . . they just missed the space funding debate at a
high-level EU space policy conference on November 8–9. The European
Commission budget head said Galileo had been "a very unhappy experience"
and the EU’s budget structure doesn't fit such "never-ending" projects.
3. Moscow, Russia and Palo Alto, California USA
THE COOL FACTOR
Apple included GLONASS in the iPhone 4S. Talk about hipster cred. Financial daily Vedomosti featured the story on October 20 and said GLONASS has "suddenly reached a massive global market." To top it off, Russia successfully launched three more GLONASS-M satellites on November 4 — a success for the recently mishap-prone Roscosmos.
4. Katmandu, Nepal
Asia-Pacific infectious disease experts combined GPS and genotyping to track typhoid fever in Katmandu, Nepal. They mapped sick houses using GPS coordinates and genotyped bacteria from each patient. How did people get sick? Mainly by infected water from bottomlands, not by person-to-person contact. This discovery suggests that typhoid can be eradicated quite simply by cleaning up public water supplies.
5. Beijing, China
STILL WAITING . . .
At September's ION GNSS conference, Xiangcheng Ding of the China Satellite Navigation Office confirmed that the Compass/BeiDou2 signal Interface Control Document will be published in 2011. We know it has existed in Chinese and English versions since at least 2009 . . . dare we get our hopes up once again?

4. Bagmati River in Katmandu, Nepal. 2005 photo by John Kim. The river's source is south of the Himalaya and the upper reaches are dammed. Its flow is dependent on rainfall, becoming very low from April to early June. It is polluted by agricultural and human waste and untreated garbage from the city.
