Both the ship and helicopter were outfitted with NovAtel's SPAN-SE-D™ dual antenna GNSS/INS receivers. The ship system used two NovAtel 702GL antennas. The ship system used a Northrop Grumman LN200 IMU, while the helicopter system used a Honeywell HG1700 AG58 IMU.
The data links used between the SPAN-SE-D receivers were Microhard 2.4 GHz IP2421 frequency hopping spread spectrum RF modem radios. The data links transmitted differential correction data between the ship and the helicopter as well as transmitting the navigation solution back to “command center”.
