    This is a table of contents for surveys at ao. It is a work in progress.

table of survey history

• First place to look to see what was done yet. does not have much detail
• have not included primary surveys yet...
  

survey coordinate systems, reflector definitions

• dome centerline coordinates
• feed coordinate system
• reflector definition files (ray trace)
• target locations, .dsn files used by theodolite surveys.

Surveying the primary reflector

• includes the measured datasets
  

Surveying the dome from AO9

Horn surveys:

• measured horn positions with needed corrections for all horn surveys.
• Compare pointing model offsets for the different rcvrs.
• shows anomalies in feed positioning  (last updated may04).
• Use astronomical sources to find the best turret position
• last done 2002

Survey equipment:

Theodolites/total stations

• leica 
  
• tm50 total station:
• nova tm50  station Users Manual (.pdf)
• chapter 7 has the technical specs.
  
• We've ordered a tm50
• We demo'd  a tm50 at ao
• from ao9 in scan mode it took up to 7 secs to measure a single point on the dish about 100m away.
• I could not do the automatic target recognition on a secondary target when shooting from the window in the turret room. We  started very close to the target, and it did not acquire it.
  
• ms60 total station
  
• leica ms60/ts60 User manual (.pdf)
• chapter 7 has the technical specs.
  
• Software:
  
• leica nova series technical reference manual (.pdf)
• This is the software that runs on the tm50 nova series total stations.
• communicating over rs232 to device:
  
• tps1200 geocom reference manual (.pdf)
  
• Software commands you can use to control the tm50 via the rs232 line.
• gsi online for leica tps (.pdf)
• command formats.. not sure if it is also valid for the tps1200?
  
• Misc:
  
• wfd Wave form digitizer technology (.pdf)
• used by ms60. Not used by tm50.
• Sokia
• ix-1000 series robotic total station  operators manual (.pdf)
• chapter 26 has the technical specs.
