Hello Workshop Attendee,
Lighthouse Technology and Consulting Co. Ltd. (LHTC) is starting a program to collect precise GNSS data on major highways in Japan. The data is intended to serve as a tool for high-precision positioning systems used in automated driving vehicles.
Automated driving on public streets has issues to overcome, and the competition to develop the technology among companies are gradually accelerating due to recent technologies’ progress in sensors, image recognition and artificial intelligence.
In addition, the Japanese Quasi-Zenith Satellite System (QZSS) has brought attention to centimeters leveled high-precision positioning.
When dealing with satellite positioning technology for automated driving systems, it is inevitable to have a variety of high precision field data at the point of development, testing, and fine tuning prior to the driving test of the vehicles, and to have the reference position data at the point of evaluation.
LHTC is planning to finish the data collecting by December 2017, and after consolidating the data, will start the service to provide the data package Mobile GNSS Field Data Set and high-precision positioning system products for developing mobile vehicle applied technology.
Mobile GNSS Field Data Set is a package of field data and precise reference position data, intended to accelerate the development speed for consumers by decreasing the time and cost to systemize and do all the data collecting by themselves.

A launch schedule for future BeiDou satellites was reported on a space news discussion board. According to the schedule, the government of China is planning to launch 32 satellites through 2020.
The schedule includes nine BeiDou-3 MEO satellites launched this year, and one replacement for a BeiDou-2 satellite, which retires in January 2018.
The schedule is below:
It will be held at Sydney, NSW, Australla from Feb. 8 to Feb. 12 2016.
ITRF2014 is the new realization of the International Terrestrial Reference System. Following the procedure already used for the ITRF2005 and ITRF2008 formation, the ITRF2014 uses as input data time series of station positions and Earth Orientation Parameters (EOPs) provided by the Technique Centers of the four space geodetic techniques (VLBI, SLR, GNSS and DORIS). Based on completely reprocessed solutions of the four techniques, the ITRF2014 is expected to be an improved solution compared to ITF2008.
