NIC, the Navigation Information Center
Port side of NIC looking forward. Center photo is the plotting table where the Navy stood it's NIC watches. SINS Navigation errors were plotted here.
On the left of the table is the IBM Selectric which was the I/O terminal of the NAVDAC CP-677 computer, just visible at an angle on the left. Above the
table are the displays for the two EM Logs. On another steel table on the right are the two Sperry AN/WPN-3 Loran-C Receivers. The IBM Selectric in the
right forground is the SINDAC terminal.

Left bottom, the CalComp plotter buffer (it's an ugly blue color which clashed with the haze gray of every other piece of equipment in NIC!). Next right,
a stack of three A-D coverters which provided digital input to NAVDAC (I forget what signals-roll, pitch and yaw?). Above the A-Ds is the CCTV monitor which
displayed the CalComp plotter one deck below in Hydroplot. Next right, atop the steel rack, are the paper tape reader and punch which loaded and wrote out programs
and program data for NAVDAC. Next right, the Bunker Ramo CP-677 computer, NAVDAC, which ran the OSP (Ocean Survey Program). Far right is the NAVDAC IBM Selectric
and the plotting table displayed in the previous slide.

Starboard side of NIC, looking aft. The SINS binnacle is visible just right of center frame.

On the left, three of the four cabinets of SINDAC, the SINS Data Analysis Computer of the Sperry Mk 3 SINS. The fourth cabinet and IBM selectric I/O device,
off frame left, are visible in slide 1. On the right, mounted on the overhead, is the SINS binnacle. In between, the cylinder mounted on the deck is the Mk-19
Gyroscope Master Compass.
NIC
Communications equipment pictured here include a URC-32 HF SSB transmitter in the rack at right. An R-1051 HF SSB receiver is mounted on a shelf with a pair of
URA-17 FSK TTY converters above it. Just to the left of them there is a TTY patch panel and what looks like a crypto switch box. Mounted on the left side of the model 28
Teletype is probably a KWV-7 remote control box for a KW-7 TTY crypto device, not pictured. Just visible on the left is the receiver of the AN/BRN-3 Satellite Navigation set.
Far right, the CalComp plotter buffer.

The three cabinets on the left are signal distrubution switch panels. Mounted somewhere in one of the racks on the right is an atomic clock (frequency standard).

On the left is the Mk 19 Gyrocompass Control Cabinet. Far right is the plotting table shown in slide 1. [Admin]
Survey Control
The 1974 incarnation of Survey Control, previously located on the 03 Level just aft of the Bridge, now moved to the third deck next to NIC. The NAVOCEANO Oceanographers
stood watches here.
Survey Control
A pair of precision depth recorders.
