| Outline of Annual Research Achievements |
The results for the theoretical investigations of this research are published both as conference proceedings and journal papers. These publications include a survey paper that reviews the existing small satellite magnetometer calibration algorithms that are capable of estimating time-varying errors and papers that propose different new approaches for magnetometer calibration.
The main part of the experiments are now concluded. At the moment we are evaluating the proposed magnetometer calibration algorithms using the measurement data obtained with the experiments. Additional experiments are being performed when necessary. Journal paper(s) that are discussing the results and comparing different approaches for magnetometer calibration using the obtained real data are being prepared.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Theoretical studies and the main part for the experiments are concluded. The reason for slight delay in the initial research plan is the necessity to have a deeper analyses for the experiment results. The magnetometers are prone to several errors in the experiment environment and it is impossible to have the exact conditions as it would be in space. Thus we need to isolate the error sources and this process needs careful detailed work on the collected experiment data. Besides, we have obtained promising results and we would like to publish a more comprehensive analyses about both the experiment results and the evaluation of the proposed magnetometer calibration algorithms using the real data.

| Strategy for Future Research Activity |
The next step of the research is finishing the evaluation of the obtained experiment data and publishing the results in journal papers. We plan using the remaining budget for attending additional conferences, if possible, and “open access” publication of the research results.
We also consider testing the proposed magnetometer calibration algorithms with actual in-flight data from a small satellite mission. In this context we are discussing the possibilities. This will be the final step in this research.
|
| Causes of Carryover |
The incurring amount is left for the next year because we would like to use it for 1) attending a more suitable conference that we can get fruitful feedbacks to our research results; 2) paying the fees for publishing the research results in an open access journal. One of the journal papers, which will be submitted to an open access journal is now being prepared.
With the total amount transferred to the next fiscal year we plan publishing two open access journal papers and attending to one international conference.
