[IGSSTATION-4173] Long Time GMSD Data Outage

[Nakamura Shinichi]

Author: Shinichi NAKAMURA, JAXA

Dear Colleagues,

Site ID:  GMSD
IERS DOMES No.:  21749S002
Location: Nakatane town, Kagoshima, Japan
Agency:  Japan Aerospace Exploration Agency

We removed existing GPS receiver, Novatel DL-V3, on 30 November.
We set up new GPS receiver, Trimble NetRS, under existing GPS
antenna, Novatel GPS-503, at GMSD on December.
However, new GPS receiver did not work completely.
We gave up tuning it.

Now, we started calling for bids for another GPS receiver and
another GPS antenna.
According to our bids rule, it takes a few months to close bids.

So, period of data outage will continue by middle of March.
We apologies for the inconvenience.

Best Regards,

Shinichi Nakamura
