ATNF ATUC MEMORANDUM

To: ATUC
From: Bob Sault
Date: 25November 2004
Subject Remote operation of Mopra

Scope
In the winter of 2005 it is planned that Mopra can be. used remotely from
the Narrabri Control Building. This memo gives an overview of the project
and a status report
The project aims to allow remote operation of Mopra in all the Mopra
observing bands and modes, particularly 3mm mapping/spectroscopy and VLBI.
The main components of the project are:
. Improvement of the primary monitor system and general monitoring of
the telescope environment (eg weather, mist);
. Better remote protection of the telescope infrastructure;
. Ability to recover from minor anomalous events (e.g. the need to reset
some telescope systems, and to recover from windstow events);
. Retrieval of the RPFITS data and observer data for archiving
The observing system itself is excluded from the scope. Any changes to the
user observing interface are to be considered a separate development.
For remote observing of 3mm spectroscopy, the new MMIC-based millimetre
will need to be available at Mopra. To be fully functionally for VLBI, the
"e-VLBI" network connections would need to be available. If the eVLBI
project delivery is delayed (which appears probable), we will aim have a
system where local Mopra people could be employed as casual tape changers
during VLBI sessions.
The restriction of the observing to the Narrabri Control Building is to
allow the Narrabri staff an opportunity to refine the Mopra system through
interaction with the Mopra remote observers. Additionally the Mopra primary
monitor system is replicated in the Narrabri Control Building: in the short
term we would require Mopra remote observers to have access to this. It is
possible that some new observers will be required to observe from Narrabri
so that they can be adequately supported.
The remote observing from Narrabri is a part-way step to an automated
observing system, and to observing from other locations. These are not
envisaged during the 2005 millimetre season. More details of the project
are available in the ATNF projects system.
Progress
The Mopra primary monitor system ("MAPS") dominates the critical path of
the project. This work is on track.
Mopra major projects
Remote operation (and eventual automatic operation) is in part motivated by
the thesis that Mopra is best used for a limited number of large projects.
The multi-line digital filterbank (MOPS) and the MMIC receiver will make
Mopra an attractive 3mm surveying instrument. Given uncertainties in the
delivery of these new systems, the advertising for the possibility of major
projects has been intentionally low key. Following the 1 December proposal
deadline, guidance on the sorts of projects proposed in 2005 will be
available by the ATUC meeting.
