Operator Documentation for observations from ops2
Background
- Operator training documentation (PDF). Includes project background, info on scheduling and rosters, overview of the telescopes and related hardware.
Observations on the 12m telescopes from the Control Room
These are notes on IVS observations from ops2, the six-monitor PC in the AuScope VLBI Operations room in Hobart.
If you are unfamiliar with the computers and software used at the sites and in the control room, please read this before continuing:
IVS Observations
Below is a step-by-step procedure for making IVS observations on the 12m telescopes. The current version of e-RemoteCtrl has a built-in checklist which can now be used during the setup procedure. So the first task is to start the Observing and monitoring software at each site, then e-RemoteCtrl.
Before the Observations
Timing PC Software
Check that the software on the timing PCs is running:
Field System Software
System Monitor
e-Remote Ctrl
- Next, set up the log monitor to provide warnings and alarms
The checklist should now be visible. The items in the list are described below and can be ticked off as you go
The Before Observation Checklist
Prepare the schedule file
- On occasions, the Hobart data are written to disk between scans for e-transfer to Tsukuba for ultra-rapid EOP observations. Some additional changes to the schedule files are required in this case:
RF and IF signal path
Check the maser
DBBC Configuration
The Digital Base-Band Converter (DBBC) takes the IF signals from the telescope and digitises them for the Mark5 recorder. The DBBC needs to be properly configured prior to an observation:
Mark5 Recorder setup
Next the Mark5 recorder needs to be prepared for the observations.
Clock and delay check
Test recording
System Temperature (Tsys) check
- Tsys measurement check
Antenna checks
Weather checks
Fringe check
Send a Station Ready email
Skype
- Start Skype and begin a chat session with all participating sites plus the on-call person
Starting and Monitoring
After the Observations
At the end of an observation:
