1Introduction

CSIS has been conducting GNSS trainings every year in joint collaboration with ICG/UNOOSA since January
2018. The past trainings in 2018, 2019 and 2020 were conducted at AIT, Thailand jointly by GIC/AIT,ICG/UNOOSA and CSIS/UT. This year the training was conducted online due to COVID-19. Although, online
training has limitations regarding field work to collect data, the participants were provided pre-logged
sample data files for data processing.
In this year’s training, the following trainings were organized:

Course A: GNSS Data processing for High-Accuracy Positioning using Low-Cost Receiver Systems
This is a 3-day training program to provide GNSS data processing skills for high-accuracy using
low-cost GNSS receiver systems. Refer Figure 1 for course objectives, Figure 3 and Figure 4 forcourse details.
Course B: GNSS for Policy and Decision Makers
This is a 1-day training program to provide general introduction, importance and applications ofGNSS for policy and decision makers. It is expected that educating the policy and decision makers
about the importance of GNSS will ease implementation of GNSS-related projects at the field level
wherever applicable. Refer Figure 2 for course objectives and Figure 5 for course details.

There were about 270 participants from 70+ countries for Course A and 160 participants from 60+
countries for Course B. Refer Figure 6 for training participation statistics including the past trainings.
Since the training was conducted online and there were participants from around the globe (70+countries), it was quite difficult for some participants to attend the training due to large difference in timezones. Nevertheless, many participants cope with this difficult situation to attend the training at odd hours.
We thank all the participants for their very interactive participation.
All program schedule, presentation materials and recorded audio/video are available online atICG/UNOOSA’s homepage and CSIS/UT homepage. Please refer [Link to Resource Materials] for accesslinks.

5Course Evaluation by the Participants

The participants were requested to evaluate training courses based on the following questions in thegoogle form:

5.1ID, Country of residence, Gender, Age range, Type of organization
From where did you learn about the workshop?
Were the topics of the workshop relevant to your work/job/position?
Did the workshop meet your professional needs and expectations? If answer is NO, why?
What were your professional needs and expectations related to the objectives of the workshop?
What was the overall level/quality of lectures at the workshop? Please give your reasons
What is your view of the overall organization of the workshop? Please give your reasons
Did your participation in the workshop help you to (please check as many boxes as appropriate)?
Please describe your actions/project(s) in more details
In your opinion, how would the above-described actions/project(s) benefit or impact your country
locally after being implemented in the future?
What challenges do you face in introducing?
What have you learnt at the workshop for your work or the programme/policies of yourcountry/organizations?
Your comments, suggestions or recommendations related to any aspect of the workshop

Selected Comments from the Participants
A total of 84 completed questionnaires were submitted to the organizers, including 60 (22%) fromparticipants of Course A and 24 (15%) from participants of Course B. Some selected comments arepresented below:
 The speakers give very detail explanations on the topics and answer all the questions by theparticipants.
 In general, each of the speakers had a lot of mastery on the subject, a lot of knowledge to impartand knew how to spread it optimally to all participants
 The knowledge of the speakers is world-class. The information presented is up to date and highquality. The practical exercises are useful and well prepared. I already have knowledge on RTKLIB
and u-center so I could understand everything, but this section has a lot of details that may leaveattendees a bit lost. The practical exercises were sometimes too fast and difficult to follow
remotely.
 I really learned new software/techniques on how to get a high position accuracy with low costreceivers. As a beginner in the research carrier, I gratefully enjoyed the way you did your best andshowed as how to proceed with many methods, it is really encouraging even if it is online. I hopenext time it will be help offline for more physical details. I hugely appreciated the flawless
initiatives/targets of the UNOOSA and ICG in collaboration with the University of Tokyo. Pleasekeep it up for the utmost interests of everyone in the world.
 Some presentations were easy to follow while taking notes, also noting some websites or sourcesthat might be interesting to check offline. I found those incredibly helpful and still have a lot ofPage 11 of 14

material to go through thanks to them. But some others were too fast for my taste and not as
thoroughly explained as I would have needed. This was especially critical when doing practice
examples. Some of us got lost at the beginning of the presentation and the rest was impossible tofollow. Also, there is no possibility of catching up, as the difficulty increases over the time, andgiving feedback over the chat is very limited, as the questions are only addressed at the end ofthe presentation. The second presentation where RTKLIB was used was much friendlier for nonexpert users and also easier to understand.
Very good presentations, positive side is, that enough time is for the QA
This workshop is really give me new idea in processing the GNSS data for better accuracy with low
cost. With online platform, it's easy and i think save a lots of money on travelling cost thus moreparticipants able to join. I hope the secretariat will organize more online workshop like this in thefutures.
My suggestion would be the expansion of these programs, if possible, to other many countries bycreating research centers and training local researchers.
Some presentations were being at a low level, which means that wouldn't be able to cover key
points at all. Maybe due to the time issue. The ideology underneath of this workshop is precious.
Providing free charges courses and analysis and data as well can mean a lot to those who can't beable to reach this kind of program.
More time for practice is required
I would encourage you very strongly to continue this type of events.
The presentations were research based with valid results. The presentations gave a general
operation of RTKlib which I have failed to use for the last 2 year. I got to know about the different
PPP available. I got more insight on the operation of Galileo Constellation.
