A number of GNSS experts from the United States, Denmark, Norway and China will lead a weeklong workshop on the future of satellite-based positioning technologies from August 27 through September 2 at the Slettestrand Holiday Center in North Jutland, Denmark.
The topics range from GNSS basics and Intelligent Transportation Systems to new GNSSes, new receivers and indoor navigation as well as environmental monitoring and arctic navigation. The event is organized by Stanford and Aalborg universities.

FIGURE 2: Example of a national geoid (upper diagram) and a correction surface for the transformation from the new orthometric height system to the old height system (lower diagram). Country is Switzerland. Geoid undulations range from 45 to 55 meters in ETRS89 and from -5 to +5 meters in the national System CH1903+. Lower diagram: Correction surface to transform from the new orthometric height system (LHN95) to the old height system LN02 with corrections from -0.10 to 0.55 meters.Q: How do GNSS-derived heights differ from other height systems?
A: Height estimation using GNSS always seems to be trickier than horizontal coordinate estimation.
Why?
On the one hand, the GNSS technique has error sources that are more critical in the vertical direction. Height estimates are weaker because of a combination of satellite geometry, the presence of strong correlations to other parameters, such as atmospheric delays, and the antenna phase center model applied during data analysis.

An afternoon at the 2011 symposiumThe Inertial Sensors and Systems symposium will take place at the Karlsruhe Institute of Technology in Karlsruhe, Germany on September 18 and 19, 2012. The conference will be held in English.
At this conference, formerly the Symposium Gyro Technology, the latest state of inertial sensors and navigation systems as well as gyro technology will be presented.
This includes applications of this technology, the development of new systems, components and test procedures as well as investigations on cost and marketing aspects.
Ceremonial room in the Mysore Palace, now a public museum.The 39th scientific assembly of COSPAR, the Committee On Space Research, willl take place from July 14 to July 22, 2012 at the Global Education Centre-2, Infosys Training Centre, Mysore, Karnataka, India. Mysore is known as the "City of Palaces."
The topics are fundmentals and relevance of space science and technological innovations and applications. Of particular interest to readers of Inside GNSS are sessions on atomic clocks, space weather, space debris, satellite dynamic and the ionosphere.

The event will also be hosted by the Instituto Geográfico Militar of Chile.
In addition to the meeting sessions, a technical visit to the Transportable Integrated Geodetic Observatory (TIGO) of the German Federal Agency for Cartography and Geodesy (BKG) is scheduled.
The Pyramid, a Karlsruhe landmarkIEEE’s giant robotics conference comes to Karlsruhe, Germany in 2013, with the theme "Anthropomatics-Technologies for Humans."
The event will take place at the Karlsruhe convention center (Knogresszentrum Karlsruhe) on May 6-10, 2013.
The conference covers every possible aspect of robotics development from body form and movement, programming and learning, hardware and software to lots of positioning, navigation and timing aspects.

One of the natural wonders of Jeju island.The 2012 Korea GNSS Society (KGS) Conference, previously known as the GNSS Workshop, will be held on November 8 and 9 at Phoenix Island resort on Jeju, Korea.
The general chair is Philho Peter Park, Korea Astronomy and Space Science Institute.
The event has been held since 1994, when Korea’s GPS Technology Council (now GNSS) was established.
While the English language website has some information on deadlines and conference history, information on papers and registration is available in Korean only.
