| Parameter | Description |
|---|---|
| Power | 0.5 Watts needed for full operation. If the batteries run down, the sampling rate can decrease so less power is used. |
|
Resolution |
Around 1 nT (compared to the earth’s field at the poles which is around 60 000 nT). |
|
Weight |
Less than 200 kg. Equipment needed for servicing less than 10 kg. |
|
Sampling Frequency |
Samples taken once a second for 150 milliseconds at maximum power. This decreases to once a minute if power is low over the winter. Time and position is measured using an attached GPS system. |
|
Servicing Frequency |
Normally once a year. |
|
Longest time unattended |
444 days |
|
Coldest Temperature |
-78° |
|
Highest Altitude |
10 550 ft |
