Our laboratory has dealt with GPS since when Prof. Yasuda and Prof.Namie managed. GPS originated from a military technology of USA has evolved to GNSS(GPS,GLONASS,GALILEO)&RNSS(QZSS,IRNSS). Further research&development is expected to be carried out in world scale. Our mother country, Japan commenced operation of QZSS which is composed of 3 Inclined and a geostationary orbit satellite in 2018.Number of QZSs is going to be increased to 7 by 2024.
We welcome who want to make receiver of GNSS by oneself, interested in satellite communication, building software(not only GPS/GNSS) or application using location-based information. Even a small motivation is a proper reason to join us. GNSS is a good subject for learning whole of communication. You can study in ionosphere and troposphere too. We effort toward you to become a specialist in your major as possible. We welcome who interested in Navigation, Map, various sensor like gyroscope You start with copying existing technology/measure at first but you are able to get your own idea gradually. Our aim is our students to become the people who contribute to society in field of Satellite Navigation and other ones including peaceful uses of space and ocean.
Graduate students of our laboratory willingly presented in international conference to spread their horizons as well as to fulfill their intellectual curiosity. This is why aggressive attitude for learning English is requested. Seminar/Meeting is held weekly and lab. Our members reported their progress in it about once a month. In regard to courses after graduation, the member who hope to get a job in shipping business & maritime cluster is got employed with bachelor’s degree, the member who hope to do in IT industry proceed to graduate school and is got employed by electrical manufacturer, manufacturer which specializes in GPS/GNSS and IT company with master’s degree. In recent 2~3 years our member’s carrier after graduation is fine. This good result owe to their fundamental academic ability and communication skill.
The theme related to our concern
In recent years we have been working on these subject. We happily accept student/researcher who don’t entirely interested in these theme but something concerning Satellite Positioning as well.
1. The subject using Software Defined GPS/GNSS receiver
2. Integrated RTK-Positioning Algorithm utilizing multi-GNSS
3. Evaluation of performance of Next-generation SBAS(Satellite based Augmentation System) and delay through ionosphere
4. Evaluation of reliability of Positioning results of GNSS
5.About GIS&GNSS (For Preventing traffic accident, environmental monitoring and so on)
6.Production of GNSS and sensor fusion small Robot
7.Solving a problem of Satellite Positioning in urban area
8.Technology for reducing multi-path oriented error
9.Assessment of GNSS antenna
10.Improving convenience of RTK using Low-cost receiver
11.Simulation using 3D-geographical data and utilization of them
12.Simulation using GPS Studio(Products of KOZO KEIKAKU ENGINEERING Inc.) data and utilization of them
13.The topics concerning QZSS
14.Positioning in railway and Calculation of reliability
15.Reinforcement of Single Positioning(Precise Point Positioning,PPP-AR) and utilization of it
16.Assignment in Medium length baseline RTK (Estimate ionospheric delay)
GNSS Base Station
Our laboratory broadcasts differential Information of Multi-GNSS (Rtcm3/RINEX) from base antenna on the roof of 4th experiment building. We use “Trimble NetR9” as receiver and “Trimble Zephyr2 Gepodetic” as attached antenna. Whenever you want to try out DGNSS and RTK Positioning or you need observation data for post processing contact us freely. We tell you access information to the data as soon as possible. This reference point information can be checked in this website.
