... Abridged version of notes from the RTK class.

* Set up Bluetooth communication with the GPS: ''General Survey -> Instruments -> GNSS functions -> Bluetooth''
** identify both the rover and the base GPS here.
* Set the Survey Style: ''Main Menu -> Settings -> Survey Styles''
** ''rtk int radio'' = internal radios on both gps
** ''RTK'' = use an external radio for the base.

 ** For this particular TSC3, those things are already taken care of.  So, when you enter the ''Measure'' menu and choose an activity, in effect you are fast forwarding through all of the options and parameters that you could set to just the configuration that you need to perform the activity you are after... if that doesn't make sense we can talk about this is informally or in a short course.

		+	2013 September Update
		+
		+	For visiting a new site and executing a gps survey:
		+	# Pound a rebar into the ground to use as a ground control point
		+	# Set Tripod up over Rebar.
		+	# Mount the Tribarach to the tripod
		+	# Screw the base GPS into a 6" range pole extension, and mount to the hockey puck on the tribarach
		+	# screw the antenna on to the base gps
		+	# connect the base station battery to the gps
		+	# Measure from the Middle of the blue rubber bumper on the base gps to the ground control point.
		+	# Mount the Rover GPS to the Range Pole
		+	# Connect the rover battery and antenna
		+	# The all thread center of the rangepole is extendable. Raise it until the blue rubber bumper on the rover GPS is at 1.55 meters. There is a brass knurled nut that can be spun into place to prevent movement of the all thread center.
		+	# Mount the TSC3 handheld controller to the rover GPS range pole.
		+	# Turn on the TSC3. From the Trimble Software select ''General Survey''
		+	# Next, Select ''Jobs''; ''New Job''
		+	# This will bring up a new window. The coordinate system will need to be selected.
		+	## Side note: If you want to use like the 2009 GEOID it is easiest to set that up using the Trimble Business Center on the toughbook, import this job as noted lower in this page. I think that might be generally the best practice: Set up the job before visiting the survey site actually. Anyway, if you aren't doing it that way...
		+	# Select the Coordinate System
		+	# Select it from the Library:
		+	## System: UTM
		+	## Zone: 7 = Barrow; 6 = Prudhoe... check your handheld GPS if you're not sure what zone you're in.
		+	## Datum: NAD1983 Alaska
		+	# Project Height: 100
		+	# Now the job is setup. With the Rover and Base GPS both turned on:
		+	## Click on the ''Measure'' Button
		+	## Click ''rtk int radio...''
		+	## Click ''Start Base Receiver''
		+	## For a site you've never visited before, once you start the base receiver it will prompt you for a point name.
		+	### Select ''Key In''
		+	### Select ''Here''
		+	### Name the point
		+	### Enter Antenna Height, a quantity you measured earlier in the setup process
		+	### Measured to: ''Center of bumper''
		+	## Click ''Start''
		+	## Now we'll start the rover. Again, click ''Measure'' then ''Measure Points''
		+	## The handheld will try to establish a link to the rover GPS.
		+	## You will be prompted for the base gps you wish to connect to. Index 27 is ours.
		+	# Now you're nearly ready to survey. First though the Rover GPS parameters will need to be entered.
		+	# Set the Antenna Point

-Following points as I'll be doing in Barrow is called 'Stakeout'
+So, maybe the TDL450 radio can't tie in to the barrow network, which seems to operate at 418 MHz (which makes sense since we need to receive data not transmit it):
