| Power | 6 to 28 V DC, 4.5 W |
Njord gives a survey boat both its position and its heading from two GNSS antennas, which is what an echosounder or multibeam needs to place each sounding correctly. It has a built-in UHF radio and 4G modem for corrections, and a rugged housing tested for vibration, shock and salt fog.
