China launched the 33rd and 34th BDS satellites into space via one single Long March-3B launch vehicle (as well as the Yuanzheng-1 upper stage) from Xichang Satellite Launch Center, at 9:48 Beijing Time on July 29th, 2018. These two satellites will operate on a medium-Earth circle orbit. They are the ninth and tenth BDS-3 networking satellites.
u-blox, a global provider of leading positioning and wireless communication technologies, has released the ZED-F9P multi-band GNSS module with integrated multi-band real-time kinematics (RTK) technology for machine control, ground robotic vehicles and high-precision unmanned aerial vehicles (UAV) applications.
The ZED‑F9P measures 22 x 17 x 2.4 millimeters and uses technology from the recently announced u‑blox F9 platform to deliver robust high-precision positioning performance in seconds.
The u-blox ZED-F9P is a mass market multi-band receiver that concurrently uses GNSS signals from all four GNSS constellations (GPS, GLONASS, Galileo and BeiDou). Combining GNSS signals from multiple frequency bands (L1/L2/L5) and RTK technology lets the ZED‑F9P achieve centimeter-level accuracy in seconds, the company said.
Receiving more satellite signals at any given time maximizes the availability of centimeter-level accuracy even in challenging environments such as in cities.
With its high update rate, the ZED‑F9P is suitable for highly dynamic applications such as UAVs. Featuring on-chip integration of advanced multi-band RTK algorithms, it requires no additional hardware or third-party RTK libraries. Ready to use on delivery and easy to integrate, it helps product developers quickly bring their ideas to the market.
ZED-F9P is fully geared to clearing the three main hurdles that have kept centimeter-level positioning accuracy from breaking into mass-market applications: cost, size and power consumption. Significantly smaller and more energy efficient than existing solutions, and as a cost efficient alternative, the ZED-F9P will enable new high-precision positioning applications for the mass market.
“The new ZED-F9P GNSS receiver builds on the success of our NEO-M8P high-precision GNSS module, but takes performance to another level by leveraging all the available GNSS signals,” said Mårten Ström, senior principal product management, product center positioning at u‑blox. “By making robust and affordable high-precision positioning technology more accessible, we hope to fuel innovation and enable a new generation of high-precision GNSS navigation applications.”
Engineering samples will be available at the end of July.

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:
