Sokkia Radian IS
Hardware Setup
1. Make sure that the Radian IS has fully charged batteries
installed, as described in the receiver documentation.
2. Connect the Radian IS serial cable to "COM1" on the Radian IS, plugging the other end into the controlling computer's serial port.
3. If the Radian IS is to be used as a base, connect a PDL base radio to the "COM2" port of the receiver. If the IS is to be used as a rover, connect a PDL rover radio to the "COM2" port if the receiver.
4. Power the Radian IS on with its external power switch.
5. Once the receiver finishes its self-initialization (when all the lights on the side panel go out and then the battery light lights in just one position), it is ready for use with Carlson Field. However, positions will not be able to be logged until the receiver has acquired a few satellites. The receiver has enough satellites when the center light is at the second or higher level (when it is orange instead of red).
Software Setup
6. To configure the IS for use, select "Equipment Setup" from the Field pulldown menu. This will open a menu with several options:
a) Radio Baud Rate: This radio button sets the baud rate for
COM2, the radio COM port. Make sure this number and the number the
PDL's are set for is the same.
b) Station Type: This sets whether the Radian IS is to be
configured as a base station or a rover.
c) Elevation Type: This allows selection of Geoid (MSL) or
Ellipsoidal measures for height/altitude.
d) RTK Dynamics: This sets the dynamics mode of the receiver. In
general, this setting should be set to "Dynamic/Kinematic".
e) Message Type: This sets what format of corrections this receiver
will send/receive for RTK.
f) Motion Dynamics: This is used to set the receiver's calculations
appropriate to the motion of the receiver.
g) Elevation Mask: This is the satellite elevation cutoff. No
satellites with elevation less than this number will be used in
corrections. This allows filtering out of satellites close to the
horizon, which provide less accurate calculations for
positions.
h) Send Command to Receiver: This allows a specific user-entered
command to be sent to the receiver. Mostly used for troubleshooting
with Technical support.
i) Configure Base: This configures the parameters of a base station
for the receiver (Ex: Current position, etc.)
j) Power Cycle Receiver: This powers the receiver down and then
turns it back on, clearing the main memory.
k) Save and Exit: This saves all settings changes and exit this
menu.
l) Cancel: This restores original settings and exit this menu.
To set the Radian IS up as a Rover:
7. Select "Rover" for Station Type, and set the Radio Baud to match the PDL's which are being used. Also, set "RTK Dynamics" to "Dynamic/Kinematic", and set Motion Dynamics to the appropriate option.
8. Select "Exit and Save". The receiver is now ready for use as a rover.
To set the Radian IS up as a Base:
9. Select "Base" for station type, and set the Radio Baud to match the PDL's which are being used.
For most jobs, set RTK Dynamics to "Dynamic/Kinematic" (unless you are sure that static is more appropriate-even small fluctuations from wind on the pole can cause problems in Static mode). Set motion dynamics to Foot/Walking, and then select "Configure Base Station"
10. In the menu dialog that opens, there are a few buttons:
a) Read from GPS: Read a position from the GPS and fix to that
position
b) Enter Lat/Lon: Fix to a manually entered Lat/Lon position
c) Enter State Plane Coord: Fix to a manually entered State Plane
Northing/Easting position
d) Read From File: Fix to a position read from a *.ref file.
e) Cancel: Cancel base setup
If Read From GPS is selected, the software will read once from the GPS receiver, and then fix to that position. If Enter Lat/Lon is selected, a dialog box will open and a Latitude and Longitude must be input manually. If Enter State Plane Coord is selected, a dialog box will open allowing the input of a set of Northing/Easting coordinates by hand.
Read from File will open a File>Open dialog and ask for the file name of the file to open.
Regardless of which option is selected, after the position is determined, this position will be displayed, and dialog boxes will open to enter a station id and the measured base antenna height. Once these values are entered, base setup is complete and the "Exit and Save" button can be selected to exit the Equipment Setup menu.
Sokkia 500 Series
1. Turn on Sokkia
2. Turn it Horizontally and Vertically to set it.
3. Connect Sokkia to Carlson Field
4. In Field go to Configure Field, and under equipment type put Sokkia
5. To make sure the baud rate matches, under the Field menu go to Configure Field and click on Communication Settings and check the baud rate. On Sokkia press [ESC], then [CNFG]. Scroll down or enter 4 for "Comms setup." The baud rate can be changed using the arrow keys, when done press [ESC].
6. Exit the Configure Field menu.
7. To check if units (Ft /M) matches for correct results, in Carlson Field under Settings go to Drawing Setup and select the appropriate button. On Sokkia, in [CNFG] scroll to or enter 5 for "unit" and select appropriate unit using the arrow keys.
