After 10 1/2 years of operation, the Pathfinder
Base Station was retired. |
|
10 May 2005 |
The Pathfinder receiver has been operating
intermittently. We will attempt to keep it running as long as
possible. Please use data from our CORS base
station. |
28 March 2004 -
14 May, 2004 |
The receiver stopped collecting data due to a problem in
the server. A new server was installed along with new serial
fiber transceivers. Some data is available for the period. |
| 15
July 2003 |
The
receiver stopped collecting data due to moisture in the antenna
lead. Water infiltration was possible through a small nick in
the antenna cable jacket. The damage was caused when the cover
for an air handling unit on the roof blew off during a strong
thunder storm in June. It will take some time for all the water
to seep out of the cable, and occasional outages may occur for
several weeks. |

February 2003 |
The
Trimble Reference Station will be shut down from 14:00 UTC to
22:00 UTC 17 February 2003. This down time is caused by a
planned power shutdown of the entire Courthouse as a part of the
remodeling and expansion project. |
| 2
October 2002 |
The
G.P.S. receiver was offline from 10:00 UTC to 23:59 UTC. No
reference station files were collected during this time period. |
| 6
August 2002 |
The
Trimble Reference Station was shut down from 21:30 UTC to 23:47
UTC 6 August 2002. This down time was caused by a planned power
shutdown of the entire Courthouse as a part of the remodeling
and expansion project. |
| 10
July 2002 |
At
14:30 hrs, a new dedicated fiber optic connection was put in
place to ensure connectivity to the G.P.S. receiver. |
| 2
July 2002 |
A
cable was severed during Courthouse remodeling. Connection
to the G.P.S. receiver was not possible until an alternate cable
was available. Base station files were not collected this
day. |
| June
2002 |
The
connection to the G.P.S. base station was not 100% reliable.
This caused breaks in data collection and file length was
affected. A permanent solution was installed in early
July. |
| 11
- 15 May 2002 |
The
G.P.S. receiver was off-line from 12:00 UTC on 11 May 2002 until
14:00 UTC 15 May 2002. Base station files were not
collected during this period. |

February 2002 |
The
server was shut down from 15:20 UTC until 15:59 UTC for the
installation of a gigabit network card. |
| 4
February 2002 |
A
configuration error on the Axis 2490 serial server caused the
loss of data from 12:00 UTC to 21:15 UTC. This has now be
remedied. |
| 29
January 2002 |
The
Reference Station was shut down from 16:00 UTC to 17:35 UTC to
facilitate the relocation of the server. The G.P.S.
receiver is now accessed remotely. |

December 2001 |
The
TRS was shut down from 20:12 UTC - 21:04 UTC for routine server
maintenance. |
| 19
November 2001 |
Due
to adverse environmental conditions (water), data files from
14:15 - 14:57 UTC were not collected. Building maintenance
assures us this was a one time incident. |
| 13

While
conducting maintenance on the server, data files from 12:00 -
16:06 UTC were accidentally lost. |
