History of the Developments of KSP VLBI System
- August 24, 1994
- The first VLBI experiment with Kashima-Koganei baseline.
- October 1, 1994
- Kashima and Koganei started near-daily observations (5 days a week).
- May 22, 1995
- The first VLBI experiment with Miura station.
- December 1, 1995
- Daily VLBI observations started with three stations (Kashima,
Koganei, and Miura). At the same time, The new KSP correlator began
operation with one baseline configuration.
- May 14, 1996
- Number of data channels used for the observations was incleased from
14 to 16. Thus the recording data rate became 64 Mbps.
- May 29, 1996
- The KSP correlator started operation with 3-baseline configuration.
- September 3, 1996
- The first VLBI experiment with Tateyama station.
- September 4, 1996
- The KSP correlator started operation with 6-baseline configuration.
- September 24, 1996
- Terrestrial reference frame was changed from ITRF93 to ITRF94 and
Celestial Reference Frame was changed from ICRF93 to ICRF94. All the
databases in the past were re-analysed.
- March 20, 1997
- Nutation Offsets from IAU80 model are corrected for data analysis.
- June 4, 1997
- 256Mbps real-time VLBI observations started on daily basis.
- July 28-August 1, 1997
- 5 days of continuous observations of 23.5 hours each were performed.
- September 30, 1997
- The frequency of the experiment was reduced from daily basis to
every-other-day basis, and the duration of each experiment was increased
from 6 hours to 23.5 hours.
- July 31, 1998
- Terrestrial reference frame was changed from ITRF94 to ITRF96 and
Celestial Reference Frame was changed from ICRF94 to ICRF RSC(WGRF) 95R01.
All the databases in the past were re-analysed.
